Gonioscopy in Gurgaon

Gonioscopy is an eye test that uses a special mirrored lens placed on the eye’s surface to directly view the drainage angle. The drainage angle is the structure that determines whether glaucoma is open-angle or angle-closure. Dr Shibal Bhartiya performs gonioscopy in Gurgaon with the room lights dimmed rather than under bright slit-lamp illumination. This is because bright light constricts the pupil and can make a narrow angle falsely appear open.

Gonioscopy is the gold-standard test for classifying glaucoma. The test determines which kind of glaucoma you have. That decision determines whether your treatment is drops, laser, or urgent intervention. Which is why it is extremely important.

If you’ve been told you need a gonioscopy in Gurgaon, it’s worth knowing that not all gonioscopy is done the same way, and the difference affects whether a narrow or closing angle gets caught at all.

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 1,600+ patient reviews on Google. Her PubMed-indexed research on angle-closure diagnosis speaks to her extensive work and experience in gonioscopy.

How Gonioscopy Is Done, and What It Tells Us

What you’ll experience

Your eye is numbed with anaesthetic drops, so the test itself doesn’t hurt. You may feel mild pressure but not pain. A small amount of gel is placed on a contact lens. the lens is then gently rested on the surface of your eye. You’ll be asked to look in a few different directions while I view your drainage angle through the microscope. The whole test takes about five minutes. Your vision may stay slightly blurry for 15–20 minutes afterward as the gel clears.

What the results mean for you:

  • Open angle: Your drainage channel is unobstructed. If you have glaucoma, it’s open-angle glaucoma — typically managed with drops, laser, or surgery aimed at lowering pressure over time.
  • Narrow or occludable angle: Your drainage channel is at risk of closing, even if it hasn’t yet. This changes the conversation from “treat glaucoma” to “prevent an acute attack” — often with a same-visit or near-term laser iridotomy.
  • Closed angle: The drainage channel is blocked. This is urgent. Untreated angle closure can cause a sudden, painful pressure spike and permanent vision loss within hours to days.
  • Other findings — pigment deposits, scarring (synechiae), or abnormal blood vessels. These can point to pigment dispersion syndrome, past trauma, or diabetic eye changes. Each redirects your treatment plan differently.

In short: Gonioscopy doesn’t just confirm glaucoma. It decides which kind you have, and that decision determines whether your treatment is drops, laser, or urgent intervention.

Why is Gonioscopy Important?

Gonioscopy is an eye test that visualises the drainage angle of the eye. This drainage angle is responsible for maintaining the eye pressure. Gonioscopy determines if the glaucoma is open angle, or angle closure. It’s findings depend heavily on room lighting and examiner technique. A gonioscopy done under bright slit-lamp illumination can make a narrow angle look falsely open. This is because light constricts the pupil and pulls the iris away from the drainage angle. In Gurgaon, I perform gonioscopy in a dimmed room specifically to avoid this artifact. This way, the angle is graded at its true, physiologic width, not an artificially widened one.

Why Room Lighting Changes the Result

This is one of the most under-discussed variables in glaucoma diagnosis.

When light hits the eye, the pupil constricts. A smaller pupil pulls the peripheral iris away from the trabecular meshwork, which can open up an angle that is, in normal daily conditions, narrow or intermittently closing. If your gonioscopy is done in a bright room, an angle-closure risk can be missed — graded as open when it isn’t reliably open at all.

I do gonioscopy with the room lights dimmed, so the pupil stays closer to its natural size. This is closer to how your eye actually behaves when you walk out of a bright clinic into dim evening light, or sit in a dark cinema. These are the exact conditions in which angle closure is most likely to be triggered. Where indicated, I also use dynamic (indentation) gonioscopy. This involves gently pressing the lens to distinguish a truly closed angle from one that only appears closed (appositional closure). This distinction changes management directly. It decides whether you need a laser iridotomy, monitoring, or nothing at all.

Why Experience in This Specific Test Matters

Gonioscopy is a skill-dependent test — the same eye can be graded differently by two examiners. It takes practiced technique to hold the lens steady, avoid corneal compression that distorts the view, and read subtle angle structures consistently.

Gonioscopy is a routine part of my daily glaucoma practice, not an occasional add-on test. As a fellowship-trained glaucoma and neuro-ophthalmology specialist with over 25 years in the field, and as a research collaborator with Mayo Clinic, Jacksonville, my clinical work is built around glaucoma diagnosis and long-term angle monitoring. This means I perform gonioscopy, not delegate, on nearly every glaucoma or glaucoma-suspect patient I see.

Published Research on Angle Closure

My angle-closure glaucoma work has been published in peer-reviewed journals and is indexed on PubMed, including:

Frequently Asked Questions

Does room lighting really change my gonioscopy result?

Yes. Bright light constricts the pupil and can pull the iris away from the drainage angle, making a narrow angle look artificially open. Gonioscopy done in dim lighting reflects your angle’s true, physiologic width.

What is dynamic (indentation) gonioscopy, and do I need it?

It’s a technique where gentle pressure is applied through the lens to see whether a closed-looking angle is truly closed or only appositionally closed. It’s used selectively, when the initial view suggests possible closure. This is because it changes whether you need a laser iridotomy or just monitoring.

Is gonioscopy available in Gurgaon?

Yes. I perform gonioscopy routinely in Gurgaon as part of every comprehensive glaucoma evaluation. I specifically do it in a dark room, and do the dynamic indentation where indicated.

How is this different from gonioscopy done elsewhere?

The test itself is standardised, but technique varies. Room lighting, indentation technique, and examiner experience all affect the reading. These are the specific variables I control for in every gonioscopy I perform.

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 use. 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, personalised 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.

How Dr Shibal Bhartiya Approaches Glaucoma Care

What I believe: Eye pressure is only one part of glaucoma assessment. Our aim is to prevent your quality of life.

What I do differently: I perform gonioscopy myself on every patient because treatment decisions depend on it. And I spend at least half an hour in each consult. And insist on teaching patients how to put eyedrops. And discussing not just the next steps, but also treatment options.

Who benefits most: Patients seeking a glaucoma diagnosis, treatment, or a second opinion before surgery.

Every patient gets a monitoring plan matched to how fast their disease is actually moving, not a fixed six-month or twelve-month default. Some patients need closer follow-up. Others, once stable, can safely be seen less often. Surgery is an irreversible decision, so has to be matched to the patients expectations and quality of life. Glaucoma lasers are an important part of my treatment armamentarium.

Dr Bhartiya say, “A glaucoma consult in my clinic follows a structured five-step process. Detailed history and vision assessment, comprehensive eye examination, glaucoma-specific testing (including corneal thickness, eye pressure, gonioscopy, OCT, and visual fields when needed), pupil dilation if required, and a personalized discussion of findings. Eye pressure is one input, not the whole picture. I assess optic nerve structure on slit lamp biomicroscopy, and the OCT, functional vision on visual field testing, and pressure trends together, and I look specifically at risk factors patients are rarely told about, such as central corneal thickness and disc haemorrhage, that change how a single pressure reading should be interpreted. And just a note: I take eye pressure readings, and gonioscopy very seriously, and insist on doing them myself.”

What Fellowship-Level Glaucoma Training Looks Like

Training ComponentWhat It MeansWhy It Matters for Patients
Glaucoma + cornea clinical training, plus Senior Research Associate, AIIMS New Delhi3 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 AIIMSUniquely 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 GenevaFellowship under Prof Tarek Shaarawy, a leading international authority on MIGS, within a neurosciences department rather than a standard ophthalmology unitOne 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 groupsTreatment recommendations are informed by current international research, not outdated protocols
Executive Editor, Journal of Current Glaucoma PracticeReviews and shapes published glaucoma research globallyFirst-hand, early access to emerging evidence and treatment shifts
200+ peer-reviewed publications, 28+ edited textbooksSustained contribution to the field’s evidence base, not just clinical practiceIndicates depth of subject mastery beyond routine patient care
1,610+ five-star Google reviews, Gurgaon practiceSustained, high-volume patient satisfaction across years of practice, not a handful of recent reviewsReal-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 1,610+ 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 1,610 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, 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.

How do I know if I need to see a glaucoma specialist rather than a general ophthalmologist?

You should see a glaucoma specialist if you have been told you are a glaucoma suspect, have a family history of glaucoma, have been diagnosed with glaucoma and want a second opinion, or have glaucoma that is progressing despite treatment. General ophthalmologists can screen for glaucoma, but ongoing management of confirmed or complex glaucoma benefits from fellowship-level expertise.

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
  • 1,610+ five-star reviews show consistency in patient trust and communication over time
  • Second opinions matter most before irreversible surgical decisions
  • Structured consultations, personalised risk stratification, thoughtful ethical eye care.

Avoid Glaucoma Surgery

Glaucoma can appear uncontrolled when medications are not being used consistently or correctly. Complex treatment schedules, poor eye drop technique, treatment fatigue, and medication side effects may raise eye pressure and mimic disease progression. A glaucoma second opinion can identify these issues before surgery is considered.

Not every patient with glaucoma needs surgery immediately. In many cases, improving eye drop technique, simplifying medications with fixed-dose combinations, or considering SLT laser treatment can achieve good pressure control and delay or avoid surgery. This is when a Glaucoma Second Opinion can help, says Dr Shibal Bhartiya.

A Word of Caution: Avoiding glaucoma surgery is NOT always advisable. In certain cases, the surgery is the only option, and helps prevent blindness. You must discuss the risks and benefits of your treatment protocol in detail with your glaucoma doctor before coming to a decision.

She Was Told She Needed Surgery

Anita, 63, had been living with glaucoma for nearly six years when she came to see me. At her previous appointment, surgery had been advised. Her eye pressure remained above target despite treatment, and recent visual field tests suggested possible progression. The changes were not dramatic, but they were concerning enough for surgery to enter the discussion.

She arrived carrying a large folder of records and four eye drop bottles.

As I reviewed her reports, I understood the concern. Her pressures were higher than ideal. A few visual field tests appeared slightly worse than earlier ones. Yet the optic nerve photographs showed only subtle change over time.

The clue had been present for months. I asked Anita to describe her treatment routine.

She was not avoiding treatment. She was trying very hard to follow it. The problem was that her regimen had gradually become more complicated. Four medications meant four separate bottles. Some needed morning doses. Others needed evening doses. During travel, one bottle might be forgotten. On busy days, she sometimes could not remember whether she had already used a drop.

Then I asked her to put in her medication. One drop landed on her cheek. Another missed the eye completely.

The glaucoma was real. The pressure problem was real. The possible progression was real.

But the patient was not failing treatment. The treatment plan was failing the patient. We simplified her regimen. Four separate medications became two fixed-dose combination bottles. We reviewed eye drop technique and built the schedule around her daily routine. Over the next three months, we achieved her target IOP, with the same medicines. Just in fewer bottles, and just because she learnt how to put them herself.

Over the last two years, her visual fields and RNFL OCT have been stable.

Patient details have been changed to protect privacy.

Here is What We Must Remember

Anita’s case highlights an important lesson. Not every patient with uncontrolled eye pressures needs glaucoma surgery. Sometimes the problem lies in how treatment is being delivered rather than the treatment itself. Glaucoma medications only work when they reach the eye consistently and correctly. Before treatment is escalated, it is important to understand whether the prescribed therapy is practical, tolerable, and sustainable. In this article, I explain why glaucoma treatment sometimes appears to fail and how a glaucoma second opinion can help.

Why Glaucoma Treatment Sometimes Appears To Fail

The goal of glaucoma treatment is simple. Lower eye pressure enough to prevent damage to the optic nerve. Achieving that goal is often more complicated.

Many patients begin treatment with a single eye drop. As glaucoma progresses, additional medications may be added. Over time, one bottle can become two, then three, then four. Each medication may have a different schedule.

For some patients, this becomes difficult to sustain.

In my practice, I commonly see patients who understand the importance of their medication but struggle with the practical realities of long-term treatment. Life gets busy. Travel happens. Schedules change. Even highly motivated patients miss doses.

Poor adherence does not always mean patients are careless. More often, it reflects treatment burden.

The clue had been present for almost a year in Anita’s case. Her pressure fluctuated more than expected. Her visual fields suggested borderline progression. Yet the optic nerve remained relatively stable. The pattern suggested that treatment effectiveness might be inconsistent.

When treatment appears to fail, specialists should ask several questions:

  • Is the diagnosis correct?
  • Is the target pressure appropriate?
  • Is the medication reaching the eye?
  • Is the patient able to follow the regimen?
  • Are side effects reducing adherence?

The answers can significantly change management.

The Importance of Eye Drop Technique

Many patients have never been shown how to use an eye drop correctly.

Common mistakes include:

  • Missing the eye completely
  • Blinking immediately after instillation
  • Using multiple drops at once
  • Touching the bottle tip to the eye
  • Administering medications too close together

Even small technique errors can reduce treatment effectiveness.

A simple demonstration often reveals problems that no scan or visual field test can detect.

Why Fixed-Dose Combinations Matter

Fixed-dose combinations combine two glaucoma medications into a single bottle.

Many patients assume these combinations are prescribed for convenience alone. In reality, they often improve treatment success.

A patient using four medications in four separate bottles may struggle with timing, scheduling, and adherence. The same medications delivered through two fixed-dose combinations can reduce confusion and simplify daily routines.

Fewer bottles often mean:

  • Better adherence
  • Less treatment fatigue
  • Lower preservative exposure
  • Greater long-term consistency

The most effective treatment is not always the strongest treatment. Often, it is the treatment a patient can realistically follow every day for years.

Could Laser Treatment Reduce the Need for Eye Drops?

For some patients, Selective Laser Trabeculoplasty (SLT) offers another way to lower eye pressure without adding more medications. SLT is a quick outpatient laser procedure that improves the eye’s natural drainage system. It does not cure glaucoma, but it can reduce eye pressure and, in some patients, decrease the number of medications needed.

This can be particularly helpful for patients who struggle with eye drop schedules, experience side effects from medications, or find long-term adherence difficult. While not every patient is a suitable candidate, SLT is increasingly being used earlier in the treatment pathway because it avoids many of the compliance challenges associated with daily eye drops. A glaucoma specialist can determine whether SLT is appropriate based on the type of glaucoma, eye pressure targets, and the overall risk of progression.

This is why a glaucoma second opinion should not focus only on surgery versus medications. For selected patients, laser treatment may offer an effective middle path.

How to Tell Glaucoma Progression From Treatment Problems

SymptomWhat It SuggestsWhat To Do
Rising eye pressure with stable optic nervePossible adherence issueReview medication use and eye drop technique within weeks
Borderline visual field progressionInconsistent treatment or early progressionRepeat visual field testing and specialist review
Multiple missed doses each weekTreatment burdenSimplify regimen and reassess pressure
Burning or redness from medicationOcular surface toxicityReview medications and ocular surface health
Difficulty managing several bottlesCompliance challengeConsider fixed-dose combinations
Progressive optic nerve damage despite good adherenceTrue disease progressionDiscuss laser or surgical options with a glaucoma specialist

Why This Diagnosis Is So Often Missed

Doctors naturally focus on disease progression. Sometimes the treatment process receives less attention.

Eye pressure is easy to measure. Medication adherence is much harder to assess. Many patients feel embarrassed to admit they miss doses. Others genuinely believe they are using their medication correctly.

Busy clinics may not have time to observe eye drop technique. Treatment burden develops gradually. Patients adapt to it until the regimen becomes overwhelming.

Preservatives in glaucoma medications may also contribute to ocular surface disease. Redness, burning, and irritation can reduce adherence further.

When eye pressure rises, it is easy to assume the disease is worsening. Sometimes the medication is simply not reaching the eye consistently.

Recognising this distinction can prevent unnecessary treatment escalation.

When To See an Eye Specialist

You should seek specialist evaluation, or a second opinion, if:

  • You have been advised glaucoma surgery and want a second opinion
  • Eye pressure remains above target despite multiple medications
  • Your visual field tests show possible progression
  • You struggle to remember or administer your eye drops
  • Your eyes burn, sting, or remain red after glaucoma treatment
  • You have been told everything is stable but symptoms continue

Frequently Asked Questions

Can poor eye drop technique make glaucoma appear worse?

Yes. If medication does not reach the eye consistently, eye pressure may remain elevated. This can create the impression that treatment is failing even when the prescription itself is appropriate.

Why might a glaucoma specialist recommend a second opinion before surgery?

A second opinion helps confirm whether glaucoma is truly progressing. It also evaluates medication adherence, eye drop technique, treatment burden, and medication tolerance before irreversible procedures are considered.

How do fixed-dose combination eye drops help glaucoma patients?

Fixed-dose combinations reduce the number of bottles and simplify treatment schedules. This often improves adherence and helps patients maintain more consistent pressure control over time.

Should glaucoma surgery be delayed if treatment adherence is poor?

Not always. Some patients genuinely require surgery. However, adherence problems, poor eye drop technique, and unnecessarily complex regimens should be identified and addressed before concluding that surgery is the only option.

Book a Consultation

Consider a consultation if you have been advised glaucoma surgery, if your eye pressure remains uncontrolled, or if your visual field tests show possible progression despite treatment.

A glaucoma consultation includes assessment of optic nerve health, visual field results, pressure trends, medication tolerance, and practical evaluation of how glaucoma medications are being used.

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.

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.
