Best Glaucoma Specialist in Gurgaon: What Sets Fellowship-Trained Glaucoma Care Apart

Searching for “best glaucoma specialist Gurgaon” usually surfaces a mix of general ophthalmologists, multi-specialty hospital listings, and very few fellowship-trained subspecialists. The difference matters more in glaucoma than almost any other eye condition. It is a disease that is silent until vision is already lost. The treatment decisions made early determine how much sight is preserved over a lifetime. Also, glaucoma rarely exists in isolation. Glaucoma patients frequently develop dry eye from long-term drop us. Some may present with overlapping optic nerve conditions that a purely glaucoma-trained eye can miss. This page sets out, plainly, what fellowship-level glaucoma training, cross-disciplinary training, and active research involvement actually mean for a patient sitting in the chair.

Dr Shibal Bhartiya is a fellowship-trained glaucoma specialist and Mayo Clinic Research Collaborator with over 25 years of experience. Her approach focuses on identifying risk before damage is irreversible, simplifying treatment decisions, and protecting vision long-term. Emphasis on early detection, risk assessment, and continuity of care.

Important: Glaucoma has no symptoms until significant, irreversible vision loss has already occurred in most cases. The qualifications and ongoing research engagement of the specialist you choose is important. It directly affects how early disease is caught and how treatment is sequenced.

What Fellowship-Level Glaucoma Training Looks Like

Training Component	What It Means	Why It Matters for Patients
Glaucoma + cornea clinical training, plus Senior Research Associate, AIIMS New Delhi	3 years of concurrent clinical and research immersion across glaucoma and cornea, alongside high volume, complex glaucoma case exposure; ongoing research collaborations with Prof Tanuj Dada, Head of the Glaucoma Unit at AIIMS	Uniquely positioned to manage glaucoma-related ocular surface disease and dry eye, which most glaucoma-only specialists are not specifically trained to treat
Structured fellowship, Senior Clinical Research Fellow, Dept of Clinical Neurosciences, University of Geneva	Fellowship under Prof Tarek Shaarawy, a leading international authority on MIGS, within a neurosciences department rather than a standard ophthalmology unit	One of a small number of glaucoma specialists also specifically trained to manage other optic neuropathies, not just glaucoma in isolation
Mayo Clinic Research Collaborator (current)	Active, ongoing collaboration with one of the world’s leading glaucoma research groups	Treatment recommendations are informed by current international research, not outdated protocols
Executive Editor, Journal of Current Glaucoma Practice	Reviews and shapes published glaucoma research globally	First-hand, early access to emerging evidence and treatment shifts
200+ peer-reviewed publications, 28+ edited textbooks	Sustained contribution to the field’s evidence base, not just clinical practice	Indicates depth of subject mastery beyond routine patient care
1,585+ five-star Google reviews, Gurgaon practice	Sustained, high-volume patient satisfaction across years of practice, not a handful of recent reviews	Real-world evidence that credentials translate into consistent, trusted patient experience — patients consistently describe feeling heard, having unhurried conversations, and treatment explained in terms of quality of life, not just disease numbers

When To See a Glaucoma Specialist (Not a General Ophthalmologist)

A family history of glaucoma, especially in a parent or sibling
High eye pressure found on a routine check, even without symptoms
Diabetes, high myopia, or long-term steroid use
Already diagnosed with glaucoma and considering a second opinion before surgery
Vision loss that your current doctor has not been able to fully explain
Persistent dryness, burning, or irritation alongside long-term glaucoma drop use
Considering newer surgical options like MIGS before agreeing to traditional surgery
Age over 40 with no eye pressure check in the last two years

What 1,580+ Five-Star Reviews Reflect

Patient tip: A high review volume matters less than what reviews consistently describe. Look for patterns, not just star counts. Most patients call her the best eye doctor, or the best glaucoma specialist in Gurgaon! Most also appreciate how friendly she, and how she especially takes care of children. Several patients mention how much her second opinions, as well as teleconsultations, helped them.

Patients consistently talk of her clear, unhurried explanations. They describe two being told clearly what stage their glaucoma is at. They also say that treatment decisions were explained rather than simply prescribed. In a condition where lifelong monitoring and trust matter as much as any single procedure, that consistency across nearly 1,600 reviews is itself a clinical signal.

Frequently Asked Questions

What makes a glaucoma specialist different from a general eye doctor?

A glaucoma specialist has completed dedicated subspecialty training beyond a general ophthalmology residency. This typically including a fellowship focused entirely on glaucoma diagnosis, surgical management, and long-term monitoring. This means deeper experience with complex cases, newer surgical techniques like MIGS, and treatment decisions. In Dr Bhartiya’s case, her clinical work grounded in evidence based medicine rather than general practice.

Is Dr Shibal Bhartiya the best glaucoma specialist in Gurgaon?

Dr Shibal Bhartiya is a fellowship-trained glaucoma specialist with over 25 years of experience, including dedicated glaucoma and cornea training at AIIMS New Delhi and a structured fellowship at the University of Geneva. She is a Mayo Clinic Research Collaborator, has authored over 200 publications. She has over 1,585 five-star patient reviews on google, most of which call her the best glaucoma specialist or best eye doctor!

What do patients say about Dr Shibal Bhartiya’s care, beyond her credentials?

Across more than 1,580 five-star reviews on google, patients consistently mention the human experience of care. They always mention being heard without feeling rushed, having questions answered in plain language. Patients appreciate that treatment is explained in terms of daily quality of life rather than just numbers and scans. They also appreciate her ethical, personalised care, with no unnecessary tests or surgeries.

Most patients also call her the best glaucoma specialist, or the best eye doctor in Gurgaon. Most also appreciate how friendly she, and how she especially takes care of children. Several patients mention how much her second opinions, as well as teleconsultations, helped them.

Why does training in cornea matter for a glaucoma specialist?

Long-term glaucoma management almost always involves years of preservative-containing eye drops. This commonly cause ocular surface disease and dry eye over time. A glaucoma specialist with concurrent cornea training is able to recognise and manage this overlap directly. Which means Dr Bhartiya does not have to refer patients elsewhere for a problem that the glaucoma treatment itself helped cause.

What does training in optic neuropathies add to glaucoma care?

Glaucoma is itself a type of optic neuropathy. Some patients have overlapping or atypical optic nerve conditions that can be mistaken for glaucoma or missed alongside it. Specialists trained specifically in optic neuropathies, in addition to glaucoma, are better equipped to catch these atypical presentations early and avoid misdiagnosis.

What is MIGS and why does fellowship training in it matter?

MIGS (Minimally Invasive Glaucoma Surgery) is a newer category of glaucoma surgery. This is less invasive than traditional procedures, with faster recovery and fewer complications for suitable candidates. Specialists trained directly with international MIGS researchers are better positioned to judge which patients are good candidates and to perform it safely.

Should I get a second opinion before glaucoma surgery?

Yes, particularly for procedures that are not reversible. Glaucoma surgery decisions benefit from input by a specialist with broad surgical and research experience. The right choice depends on disease stage, risk stratification and patient preference. Dr Shibal Bhartiya explains options, eye anatomy, and how the disease is likely to progress over decades. Her second opinion is not based just current eye pressure.

Key Takeaways

Fellowship-level glaucoma training (AIIMS, University of Geneva) means deeper exposure to complex cases and advanced techniques like MIGS
Concurrent cornea training at AIIMS uniquely positions her to manage glaucoma-related dry eye and ocular surface disease
Geneva fellowship was within a Department of Clinical Neurosciences, adding specific training in optic neuropathies beyond glaucoma alone
Active research collaboration (Mayo Clinic) keeps treatment decisions current with global evidence
1,580+ five-star reviews show consistency in patient trust and communication over time

Glaucoma Eye Drops: Prostaglandin

Prostaglandin Eye Drops for Glaucoma: Why Stopping Them Is Dangerous, Dr Shibal Bhartiya explains. Every week, a patient sits across…

What Does Glaucoma Vision Actually Feel Like

Glaucoma vision is often described as gradually losing side vision, making it harder to notice objects, navigate spaces, or see hazards. Because early glaucoma rarely causes symptoms, regular eye examinations are essential for early detection. Glaucoma usually develops slowly and painlessly, often affecting peripheral (side) vision before central vision. Many people do not notice symptoms until significant and irreversible vision loss has already occurred.

Glaucoma vision does not feel like anything in its early stages. That is the defining and most dangerous feature of this disease. By the time most people notice something is wrong, significant and permanent nerve damage has already occurred.

Dr Shibal Bhartiya is a fellowship-trained glaucoma specialist and Mayo Clinic Research Collaborator with over 25 years of experience. Her approach focuses on identifying risk before damage is irreversible, simplifying treatment decisions, and protecting vision long-term. Emphasis on early detection, risk assessment, and continuity of care. She is rated 5 stars across 1,500+ patient reviews on Google

What Glaucoma Vision Actually Feels Like at Every Stage

Most eye diseases announce themselves. Glaucoma does not. It is a disease of gradual, silent loss, and the experience of that loss is unlike almost anything else in medicine.

Understanding what glaucoma vision feels like at each stage helps you recognise warning signs earlier, take monitoring seriously, and explain your experience accurately to your doctor.

Early Glaucoma: You Feel Nothing

In early glaucoma, peripheral vision begins to fail. The optic nerve loses fibres quietly. No pain, no redness, no blur. Your brain fills in the gaps using information from your other eye and from past visual experience. This is called neural compensation.

You do not see a black patch. You see nothing wrong. Your brain edits the missing information out of your awareness before you ever become conscious of it. This is why early glaucoma is genuinely invisible to the person who has it.

The only reliable way to detect early glaucoma is through examination. Intraocular pressure measurement, optic nerve imaging, and visual field testing reveal damage that the patient cannot feel and cannot describe.

Moderate Glaucoma: The Gaps Begin to Appear

As glaucoma progresses, the areas of lost vision become larger. They can no longer be hidden by neural compensation alone. Patients at this stage describe experiences that are specific and worth knowing.

Missing patches that are hard to locate. Not seeing a dark spot. You miss things that were there. You reach for a glass and it is not where you expected. In fact, you may step off a kerb without seeing it. You lose track of a word while reading and cannot find your place again.

Difficulty in crowds. Faces appear and disappear unexpectedly. People seem to emerge from nowhere because they entered your visual field through an area that no longer reports properly.

Trouble on stairs and uneven ground. Depth perception requires full peripheral vision. When peripheral fields narrow, steps become harder to judge. Falls become more likely.

Slower recovery in dim light. Many patients notice that moving from a bright space to a dim one takes longer than it used to. Glaucoma damages the cells responsible for low-light sensitivity earlier and more severely than those handling bright light.

Glare sensitivity. Headlights, sunlight on water, and bright screens can feel more uncomfortable than before. This is partly nerve damage and partly the effect of raised intraocular pressure on the optical media of the eye.

Advanced Glaucoma: Tunnel Vision

In advanced disease, the visual field contracts severely. Patients describe this as looking through a narrow tube or pipe. Central vision remains sharp because the macula is often the last area affected. Patients can still read and recognise faces. But they cannot see what is beside, above, or below them.

This creates a profound and specific disability. Reading is possible. Walking safely is not. Driving is impossible. Navigating a room without knocking into furniture is a daily challenge. The disconnect between intact central vision and devastated peripheral vision confuses people who do not understand glaucoma. A patient may appear to see perfectly while being functionally blind for most activities of daily life.

End-Stage Glaucoma and Blindness

End-stage glaucoma results in the loss of central vision as well. The patient may retain light perception or hand motion vision. Full blindness from glaucoma is total loss of all functional sight. It is permanent. No treatment restores vision that glaucoma has destroyed.

This is the core clinical reality that shapes everything in glaucoma management. The damage is irreversible. The goal is always to stop further loss, not to recover what is gone.

Acute Angle-Closure Glaucoma: A Different Experience Entirely

The descriptions above apply to primary open-angle glaucoma, which is the most common type. Acute angle-closure glaucoma is different and dramatic.

In acute angle closure, intraocular pressure rises suddenly and severely. The experience is unmistakable. Patients describe intense eye pain, a headache centred around the eye and brow, nausea, vomiting, and vision that becomes blurred and hazy. They often see rainbow-coloured halos around lights. The eye becomes red. The cornea looks hazy even to an observer.

This is a medical emergency. It requires treatment within hours to prevent permanent vision loss. If you or someone you know experiences these symptoms, seek emergency eye care immediately.

Understanding Symptoms & Signs

Glaucoma Stage	What the Patient Experiences	What Standard Vision Tests Show
Early	Nothing. No symptoms.	Normal acuity, subtle optic nerve changes, early field defect on testing
Moderate	Missing objects, misjudging steps, difficulty in crowds	Reduced peripheral field on formal perimetry
Advanced	Tunnel vision, frequent falls, cannot drive	Severely constricted visual field, preserved central acuity
End-stage	Near or complete blindness	Central field loss, minimal or no functional vision
Acute angle-closure	Severe pain, halos, nausea, blurred vision	Raised IOP, corneal haze, shallow anterior chamber

Why Glaucoma Vision Is So Often Misunderstood

Patients with moderate to advanced glaucoma frequently pass standard vision chart tests with flying colours. A 6/6 Snellen result means your central vision is intact. It says nothing about your peripheral field. Doctors, family members, and even some healthcare professionals mistake a good acuity reading for good overall vision.

This misunderstanding has real consequences. Patients are told they see well when they cannot drive safely, cannot walk without risk, and cannot function independently. Visual acuity and visual field are two separate measurements. Both matter. In glaucoma, the field is the critical one.

What to Do If You Recognise These Descriptions

If what you have read here sounds familiar, act now. Glaucoma is treatable. Vision lost cannot be recovered, but further loss can almost always be stopped or slowed significantly with the right intervention.

You need a formal visual field test, an optic nerve assessment with imaging, and an accurate intraocular pressure reading taken at the right time of day. If you have already been diagnosed and your symptoms are progressing, your current treatment may not be sufficient.

A specialist opinion is not a sign that something has gone wrong. It is the most responsible thing you can do for your long-term vision.

Frequently Asked Questions

Does glaucoma cause pain?

Primary open-angle glaucoma, the most common type, causes no pain at any stage. Pain is a feature of acute angle-closure glaucoma, which is a different condition requiring emergency treatment. The absence of pain in open-angle glaucoma is precisely why it is so often diagnosed late.

Can you see the blind spots caused by glaucoma?

No. The brain fills in missing areas of visual field automatically. You do not see black patches. You simply fail to see things that fall in the damaged area. This is why patients are genuinely unaware of early and even moderate field loss.

Is glaucoma vision loss different in both eyes?

Usually, yes. Glaucoma typically progresses at different rates in each eye. The better eye compensates for the worse one. This further masks the degree of real vision loss until the disease is quite advanced in at least one eye.

How fast does glaucoma vision loss progress?

Rate of progression varies widely. Some patients lose very little vision over decades. Others progress quickly despite treatment. Pressure control, disc structure, blood flow, and genetic factors all play a role. This is why ongoing monitoring matters as much as the initial treatment decision.

Can glaucoma vision loss be reversed?

No. Optic nerve fibres that glaucoma destroys do not regenerate. Current treatment preserves remaining vision by controlling intraocular pressure and, where possible, protecting the optic nerve. Research into neuroprotection is active. There is currently no approved therapy to restore lost glaucomatous vision.

Is This a Stye?

A stye is a painful red bump on the eyelid caused by an infection of an oil gland. Most improve with warm compresses, but persistent or recurrent lumps should be evaluated by an eye specialist.

Is This a Stye? How to Tell — and When It’s Something Els

You woke up with a red, tender lump on your eyelid. It hurts to blink. You are fairly sure it is a stye — and you may well be right. But a stye, a chalazion, and meibomian gland dysfunction (MGD) are three different conditions that look similar and get confused constantly, including by people who have had them before.

I see patients who have been treating a chalazion with warm compresses for six months, expecting it to behave like a stye. I see others who dismiss a persistently blocked lid gland as something that will pass. Knowing which one you have changes what you do next.

This article helps you identify your eyelid lump accurately, understand what causes it, and know when to stop waiting and come in.

Quick Answer: A stye is a painful, red, pus-filled lump that forms at the edge of the eyelid, usually from a bacterial infection of a lash follicle or oil gland. It typically resolves in 7 to 14 days with warm compresses. A chalazion is a firm, usually painless lump sitting further back on the lid — it is a blocked meibomian gland, not an infection, and often needs a clinic procedure to resolve. MGD is the underlying gland dysfunction that makes both conditions more likely to recur.

Stye, Chalazion, or MGD: What Is the Difference?

These three conditions share the same anatomy — the eyelid’s oil-producing glands — but differ in cause, feel, and treatment.

A stye (also called a hordeolum) is an acute infection. It forms fast, hurts, and often has a visible yellow head. A chalazion is a chronic blockage without infection. It develops slowly, sits deeper in the lid, and feels like a hard pea under the skin. MGD is not a lump at all — it is a long-term dysfunction of the meibomian glands that creates the conditions for both styes and chalazia to keep coming back.

Stye

Symptom	What It Means	What To Do
Red, painful lump at lash line	Infected lash follicle or external oil gland (Zeis or Moll)	Warm compress 10 minutes, 4 times daily
Yellow or white head visible	Pus collecting — classic external hordeolum	Do not squeeze; let it drain on its own
Lump inside the eyelid, painful	Internal hordeolum — infected meibomian gland	Warm compress; see a doctor if no improvement in 5 days
Swelling spreads to surrounding lid	Infection spreading beyond the gland	See a doctor promptly — may need antibiotics
Recurring styes in same location	Blocked gland or underlying MGD	Requires lid hygiene assessment, not just treatment of current stye
Stye in a child	Same mechanism, but children rub eyes more and delay healing	Warm compress; see a doctor if no change in 48 hours

Chalazion

Symptom	What It Means	What To Do
Firm, round lump in mid-lid, not at lash line	Blocked meibomian gland — not an infection	Warm compress 10 minutes, 4 times daily for 4 to 6 weeks
Lump is painless or mildly tender	Chronic granulomatous inflammation, not acute	No antibiotics needed unless secondarily infected
Lump has been there over 6 weeks with no change	Unlikely to resolve without intervention	See an ophthalmologist for incision and curettage (I&C)
Lump pressing on eyeball, blurring vision	Mechanical pressure on cornea	See a doctor — this needs prompt attention
Recurrence after treatment	MGD driving repeated blockages	Treat the gland dysfunction, not just the lump
Large chalazion in a child	Can cause amblyopia if it distorts vision	Paediatric ophthalmology referral

MGD (Meibomian Gland Dysfunction)

Symptom	What It Means	What To Do
Gritty, burning eyes — worse in the morning	Thickened meibum blocking tear film stability	Warm compress daily + lid massage
Eyelids feel crusty or stuck on waking	Inspissated gland secretions	Lid hygiene twice daily with a clean cloth or lid wipe
Frequent styes or chalazia	MGD is the root cause — glands chronically blocked	Address MGD, not just individual lumps
Frothy or foamy tears at lid margin	Bacterial overgrowth on lid margin secondary to MGD	Tea tree oil lid scrubs if Demodex suspected; see a doctor
Reduced or absent oil expression from lids	Glands are atrophying	Ophthalmologist assessment — early intervention matters
Dry eye symptoms alongside lid problems	Tear film instability from poor meibum quality	Omega-3 supplements, warm compress, preservative-free drops

How to Tell a Stye from a Chalazion at Home

Location matters most. A stye sits at or very close to the lash line. A chalazion sits higher up on the lid, away from the lashes, and you can often feel it as a distinct firm nodule under the skin.

Pain is the second clue. Styes hurt. Chalazia usually do not, unless they become secondarily infected.

Speed of onset is the third. If it appeared overnight and is throbbing, it is likely a stye. If you noticed it gradually over days or weeks, suspect a chalazion.

What To Do at Home

These measures work for both styes and chalazia in the early stages.

Apply a warm compress for 10 minutes, four times a day. The compress must be genuinely warm — a flannel soaked in hot water and wrung out, or a clean heated eye mask. Warmth softens the blocked secretion and helps drainage.
After the compress, gently massage the lid in the direction of the lashes to encourage the gland to express.
Do not squeeze, pop, or pierce the lump. This risks spreading infection and causing scarring.
Remove all eye makeup while the lump is active. Mascara and eyeliner worsen gland blockage.
Do not wear contact lenses until the stye has fully resolved.
If you have recurrent episodes, start daily lid hygiene as a long-term habit — not just when a lump appears.

When To See a Doctor

Do not wait if you notice any of the following:

The lump is not improving after warm compresses
A chalazion has been present for more than 2 weeks without change
Swelling is spreading beyond the eyelid to the cheek or brow
You have fever, significant pain, or the eyelid is hot to touch
Vision is blurred or you feel pressure on the eye
The lump is in a child and affecting how the eye opens or moves
You have had the same lump treated and it has returned in the same spot
You are on immunosuppressants, have diabetes, or have had previous eyelid surgery

A lump that keeps returning in the same location needs a biopsy to rule out a sebaceous gland carcinoma. This is rare, but I do not skip it — and neither should your doctor.

Medical Treatment Options

For Styes

Most styes resolve with warm compresses alone. If they do not, an ophthalmologist may prescribe a short course of topical antibiotic drops or ointment. Oral antibiotics are rarely needed unless the infection has spread. A stye that is pointing but not draining can be lanced under local anaesthetic in a clinic setting — a quick, painless procedure.

For Chalazia

A chalazion that has not responded to four to six weeks of warm compresses needs an incision and curettage (I&C). This is a minor procedure done under local anaesthetic in clinic. The lid is everted, a small incision made on the inside surface, and the granulomatous contents removed. It takes under 10 minutes. Recurrence after I&C is common if underlying MGD is not treated.

An intralesional steroid injection is an alternative for patients who prefer to avoid surgery, or for chalazia in cosmetically sensitive locations. It works well for soft, early chalazia.

For MGD

MGD is a chronic condition and needs ongoing management, not just treatment of individual episodes. The approach includes:

Daily warm compress and lid massage (long-term, not just during flares)
Lid hygiene with baby shampoo or a dedicated lid scrub, twice daily
Omega-3 fatty acid supplementation — evidence supports this for meibum quality
In-clinic treatments including meibomian gland expression, intense pulsed light (IPL) therapy, or LipiFlow for more severe cases
Demodex treatment with tea tree oil lid scrubs if mite infestation is contributing

Frequently Asked Questions

Can I pop a stye at home?

No. Squeezing or piercing a stye risks spreading the infection deeper into the lid or into surrounding tissue. Let it drain on its own with warm compresses.

How long does a stye take to go away?

Most styes resolve in 7 to 14 days with consistent warm compresses four times daily. A lump that persists beyond two weeks needs a clinic review.

Is a chalazion the same as a stye?

No. A stye is an acute bacterial infection at the lash line. A chalazion is a chronic blocked gland, usually painless, sitting deeper in the lid.

Why do I keep getting styes?

Recurrent styes usually indicate underlying meibomian gland dysfunction (MGD), which blocks glands repeatedly. Treating the MGD — not just each individual stye — breaks the cycle.

Can MGD cause a stye?

Yes. MGD thickens the oil secretions in the meibomian glands, making blockage and secondary infection more likely. It is the most common underlying cause of recurrent styes and chalazia.

When does a chalazion need surgery?

A chalazion needs incision and curettage if it has not responded to warm compresses after four to six weeks, is large enough to press on the eye, or is affecting vision or lid position.

Key Takeaways

A stye is painful, fast-forming, and sits at the lash line — it is an infection
A chalazion is firm, usually painless, and sits deeper in the lid — it is a blockage, not an infection
MGD is the root cause of most recurrent styes and chalazia
Warm compresses four times daily are the first treatment for both styes and chalazia
Never squeeze or pop an eyelid lump
A chalazion lasting more than six weeks needs a clinic procedure
Recurrent lumps in the same spot need a biopsy to rule out malignancy

Book a Consultation

If your eyelid lump has not resolved in two weeks, keeps coming back, or is affecting your vision or comfort, I would encourage you to come in for an assessment. Styes and chalazia are very treatable — but they need the right diagnosis first, particularly if MGD is driving the pattern.

I see patients at my clinic in Gurugram and offer second opinions for eyelid conditions that have not responded to previous treatment.

Glaucoma Progressing Despite Normal Pressure: 24 Hour IOP

Glaucoma progression despite apparently controlled intraocular pressure is one of the most disorienting experiences a patient can face. It is also one of the most common reasons patients seek a glaucoma second opinion. The reason is almost always the same: daytime clinic readings capture one moment. They do not capture what happens at night, explains Dr Shibal Bhartiya.

Not all glaucoma medications lower pressure around the clock. Brimonidine and timolol both show significantly reduced activity after midnight. A patient whose pressure is controlled at 11 am may have entirely uncontrolled pressure at 3 am — and no standard clinic visit will reveal this.

My Glaucoma Is Progressing But My Pressure Is Always Normal. What Is Going On?

He was in his early sixties — careful, informed, and deeply confused.

He came to me for a second opinion after five to six years under glaucoma care. His file was meticulous. His lifestyle was exemplary — non-smoker, controlled blood pressure, controlled blood sugars. He was on two medications: timolol and brimonidine. His baseline IOP had been 26 to 27 mmHg. On treatment, it now sat at 13 to 14 mmHg at every clinic visit for years.

By every standard measure, he was a success story. But his glaucoma was still progressing.

He was not angry. He was bewildered. I have done everything right, he told me. Why is this still happening?

That question deserved a better answer than he had been given. The answer was in the hours nobody had measured.

The question nobody had asked

I looked at his records and asked him one thing: had anyone ever done a diurnal variation for him? A 24-hour IOP measurement, mapped across day and night? Or a Water Drinking Test?

He said no.

We enrolled him in a study using the Triggerfish sensor — a contact lens device that records continuous IOP fluctuation over 24 hours. The device does not measure absolute pressure values, but it maps the pattern of fluctuation with precision.

The night-time readings were almost double the daytime values.

Most clinic visits measure pressure once, mid-morning, when he was up and about. That is the reading least likely to catch a nocturnal spike. His reassuring numbers, always 13, always 14, had been capturing only half the story. The other half was unfolding while he slept, while no one was measuring, while his optic nerve absorbed damage that nobody anticipated.

Why his medications were failing him at night

The reason was pharmacological, and it is something worth stating clearly: brimonidine and timolol do not work at night. Their pressure-lowering effect drops sharply in the late hours. His reassuring clinic readings — always 13, always 14 — had been capturing only half the story. The other half was invisible, unfolding while he slept, while no one was measuring, while his optic nerve absorbed damage that nobody anticipated.

This is not a failure of the medications. It is a failure of the measurement system — and of the assumption that a daytime number tells the whole story.

What Doctors Often Miss

Brimonidine and timolol do not work at night. This is pharmacology, not failure — their pressure-lowering effect drops sharply in the late hours. It is a well-documented limitation that is not always communicated to patients or factored into treatment decisions.

The result is that a patient can have genuinely excellent daytime control and entirely uncontrolled nocturnal pressure simultaneously. Standard clinic visits — timed to office hours — will never detect this.

The other missed step is the diurnal variation test itself. It is one of the most underused and highest-yield investigations in glaucoma management. It is rarely ordered unless a specialist specifically suspects nocturnal IOP spikes. If your glaucoma is progressing despite apparently good readings, this investigation is worth asking for by name — and a glaucoma second opinion is always reasonable in this situation.

Why Prostaglandins Are First-Line for a Reason

We switched him to bimatoprost 0.01% — a prostaglandin analogue. Prostaglandins are the only class of glaucoma medication proven to work continuously across 24 hours. They do not lose activity at night.

That was in 2012 to 2013. He has been stable for over six years.

One molecule change. One question that had never been asked. Six years of stability that five years of treatment had never delivered.

Symptoms, Pressure Patterns, and When to Investigate

Finding	Likely Cause	When to Investigate Further
Glaucoma progressing despite good clinic IOP	Nocturnal IOP spike not captured by daytime readings	Request 24-hour diurnal variation assessment
On timolol or brimonidine, still progressing	Night-time loss of drug efficacy	Ask whether a prostaglandin has been considered
Visual field deterioration at routine review	Ongoing IOP fluctuation between clinic visits	IOP fluctuation may be as damaging as sustained elevation
Good compliance, good lifestyle, still progressing	Medication class mismatch for 24-hour coverage	Second opinion from glaucoma specialist
Pressure controlled but OCT showing RNFL thinning	Structural damage continuing despite IOP numbers	Full diurnal assessment and treatment review

What This Means for You

If your glaucoma is progressing despite readings that look controlled, the readings may be incomplete — not the whole story, only the morning chapter.

The questions worth asking at your next visit: Has my pressure ever been measured at night? Has anyone checked whether my medications work across 24 hours? Has a prostaglandin analogue been considered as my primary medication?

You are not doing anything wrong. The measurement system may simply be missing the hours that matter most.

If your glaucoma is progressing despite treatment, or if you have never had a 24-hour IOP assessment, a specialist review may give you answers years of routine care have not.

FAQs

My glaucoma is progressing but my eye pressure is always normal at the clinic. How is that possible?

Clinic readings capture pressure at one moment, usually mid-morning. Eye pressure fluctuates across 24 hours. Certain medications — including timolol and brimonidine — lose effectiveness at night. If pressure spikes at 2 am, no daytime clinic visit will catch it. That spike is still damaging your optic nerve, invisibly, visit after visit.

What is a diurnal variation test and do I need one?

A diurnal variation maps your eye pressure across the full day and night. It is recommended when glaucoma is progressing despite apparently controlled pressure, when you are on medications that may not provide round-the-clock coverage, or when your specialist suspects night-time IOP spikes. It is one of the most underused and highest-yield tests in glaucoma management.

Why are prostaglandin eye drops the first choice for glaucoma?

Prostaglandins are the only class of glaucoma medication that works continuously across 24 hours. Other drugs — including timolol and brimonidine — show significantly reduced activity at night. For long-term pressure control, the night-time hours matter as much as the daytime ones. This is why prostaglandin analogues are recommended as first-line therapy in international glaucoma guidelines.

Can glaucoma progress even when I am doing everything right?

Yes, and it is more common than patients realise. Controlled daytime pressure, healthy lifestyle, medication compliance — none of these guarantee protection if night-time IOP is unaddressed. Progression despite apparent control is a signal to investigate further, not to doubt yourself. A glaucoma second opinion is always reasonable in this situation.

Should I ask for a 24-hour IOP test if my glaucoma is progressing?

Yes. If your visual fields are declining despite good clinic readings, a diurnal variation assessment is a reasonable and important next step. Ask your glaucoma specialist specifically about this. It is a question worth asking at your next visit.

Note: Contact Lens Monitor for Continuous IOP Monitoring

Triggerfish® contact lens sensor is a specialised diagnostic contact lens used in glaucoma care to monitor intraocular pressure (IOP)–related changes over 24 hours. Unlike routine pressure measurements taken during clinic hours, the Triggerfish lens (Sensimed Triggerfish) helps detect pressure fluctuations that may occur at night or outside OPD visits, which can sometimes explain progression despite apparently controlled readings. It does not measure pressure directly in mmHg but records circumferential corneal changes related to IOP patterns, helping glaucoma specialists better understand individual risk profiles and treatment needs in selected patients.

Dr Shibal Bhartiya was the first doctor in India to use the Triggerfish® contact lens sensor for Continuous IOP Monitoring in clinical practice. Her initial experiences on Intraocular pressure (IOP) related pattern in patients with primary angle closure (PAC) and primary angle closure glaucoma (PACG) before and after laser peripheral iridotomy (LPI) was presented at ARVO, in Orlando Florida in 2014

IOP Fluctuation and Angle Closure Glaucoma

IOP fluctuation is a particular concern in angle closure disease, where pressure spikes can be steep and are frequently missed by routine daytime readings. Dr Bhartiya’s published research has examined this directly. A 2015 study in the Journal of Current Glaucoma Practice, Diurnal Intraocular Pressure Fluctuation in Eyes with Angle-Closure (Bhartiya S, Ichhpujani P; PMID: 26997828), investigated IOP fluctuation across the day in 77 newly diagnosed angle closure patients and documented the range and pattern of diurnal variation in this group.

A 2019 review in the Romanian Journal of Ophthalmology, Diurnal Variation of IOP in Angle Closure Disease: Are We Doing Enough? (Bhartiya S et al.; PMID: 31687621), went further — finding that many clinical decisions in angle closure glaucoma management are based on only one or two IOP measurements, and arguing that this is insufficient given the established circadian rhythm of IOP and its direct correlation with glaucoma progression. Taken together, these papers make the case that angle closure patients may be among the most undertreated precisely because their worst pressure moments are the least observed.
