Glaucoma is the leading cause of irreversible blindness worldwide, and one of the most under-diagnosed conditions in India. As a fellowship-trained glaucoma specialist in Gurgaon with 25+ years of experience, I have seen what happens when glaucoma is caught early and managed well. I have also seen what happens when it is not. This page explains my approach to glaucoma care, and why the thinking behind treatment matters as much as the treatment itself.
It’s important you understand how I think about glaucoma. Glaucoma is usually not an emergency, and it is not a single decision. It is a condition that unfolds slowly, quietly, and over years, often without symptoms early on. Because the damage it causes cannot be reversed, how we think about glaucoma matters as much as what we do.
My approach to glaucoma care is built around one central principle:
Protecting vision, and quality of life, over the long arc of a person’s life.
My Clinical Approach
My clinical approach to glaucoma focuses on five principles:
Early detection matters more than late rescue
Structural damage often begins long before symptoms. Identifying risk early prevents irreversible loss.
Risk matters more than a single eye pressure number
Treatment decisions must consider age, corneal thickness, optic nerve structure, family history, and progression risk, not just pressure readings.
Progression matters more than test results in isolation
Single reports can be misleading. What matters is change over time.
More treatment is not always better treatment
Adding drops without clarity can increase side effects without improving outcomes.
Continuity of care prevents silent progression
Glaucoma management is a long-arc process, not a one-time decision.
This philosophy guides how I review every glaucoma patient.
You may benefit from specialist evaluation if:
- Your reports appear normal but your doctor still suspects glaucoma
- You have been advised multiple medications quickly
- Your visual field reports appear to fluctuate
- OCT reports show changes but you have no symptoms
- Surgery has been advised early
- There is a strong family history of glaucoma
- You feel uncertain about the long-term plan
In many cases, patients do not need more treatment, they need better interpretation of existing data.
How I review a glaucoma patient
When I evaluate a glaucoma patient, I typically review:
Clinical history
Duration, prior pressures, medication response, family history.
OCT scans
Not just the colour coding, but structural patterns and change over time.
Visual fields
Trend analysis rather than single reports.
Optic nerve examination
Clinical correlation beyond imaging.
Risk profile
Age, life expectancy, progression likelihood, treatment burden.
Functional impact
Reading difficulty, contrast problems, navigation challenges.
Treatment sustainability
Whether the current plan is realistic for long-term adherence.
The goal is not just diagnosis, but safe long-term risk management.
Glaucoma Care in Gurgaon: Why Early Risk Assessment Changes Everything
Glaucoma Is a Risk Problem Before It Is a Vision Problem. Most people with early glaucoma feel completely fine. Vision may seem normal. Daily activities are unaffected. There is no pain, redness, or warning signal.
Yet glaucoma causes gradual, permanent damage to the optic nerve.
That is why waiting for symptoms is not neutral in glaucoma care. By the time vision loss is noticed, opportunities to protect it may already be reduced.
Early glaucoma care focuses on:
- Understanding risk, not just current damage
- Identifying who is likely to progress, and how fast
- Acting while we still have time to protect future vision
Glaucoma is best managed before it becomes visible in daily life.
What We Are Really Trying to Preserve
In glaucoma, we are not treating a number.
We are protecting quality of life.
The World Glaucoma Association defines target eye pressure as the pressure level at which glaucoma progression is slow enough that it is unlikely to affect a person’s quality of life during their lifetime.
This definition is important.
It means glaucoma care is not about achieving a single “normal” value.
It is about preserving:
- Quality of vision: vision that supports reading, mobility, independence, and confidence
- Quality of life: living without avoidable fear, crisis, or late regret
In practice, this means we optimise for:
- Useful vision over decades, not perfect reports today
- Stability rather than drama
- Treatment plans that protect eyesight and fit into real life
The goal is not perfection.
The goal is slowing the disease enough, early enough, so that glaucoma never becomes the thing that limits how you live.
Why Treatment Is Often Stepwise
Glaucoma is a lifelong condition.
Every treatment choice has long-term implications.
Medication, laser, and surgery are not competing options.
They are tools used at different points along the disease timeline.
Depending on the stage and risk profile, I may recommend:
- Careful observation with structured monitoring
- Eye drops to reduce risk of progression
- Laser treatment to improve pressure control
- Surgery when stronger protection is required
The key question is never “Can we do something?”
It is always “What best protects this eye- and this person’s life- over time?”
Why Surgery Is Not Always the First Answer
Glaucoma surgery can be powerful and vision-saving when done at the right time.
But it is also often irreversible.
Operating too early can:
- Reduce future treatment options
- Introduce lifelong risks before they are necessary
- Solve today’s problem at the cost of tomorrow’s flexibility
Choosing not to rush into surgery does not mean inaction.
It means respecting the long-term nature of glaucoma and preserving options while the disease allows us that space.
When Glaucoma Surgery Becomes the Most Conservative Choice
There are times when continuing to wait carries greater risk than intervening.
In glaucoma, surgery becomes appropriate when:
- The disease is progressing despite appropriate treatment
- Structural damage is advancing, not just pressure numbers changing
- Remaining vision needs stronger protection
- Delaying further would compromise long-term outcomes
At this point, surgery is no longer aggressive.
It becomes the most conservative way to protect vision and quality of life.
When I recommend surgery, I do so with clarity about:
- Why this moment matters
- What surgery is expected to achieve
- What it cannot reverse
- How care continues afterward
Surgery is a step in glaucoma care- not the endpoint.

What I Want Patients to Understand
Good care is not driven by fear or urgency.
It is driven by:
- Thinking ahead
- Making informed decisions early
- Preserving options for the future
- Protecting vision and quality of life quietly and consistently
This is how sight is saved in glaucoma: not dramatically, but deliberately.
If you have been told you have glaucoma, or are at risk, this page is not meant to rush you.
It is meant to help you ask better questions. If you are unsure where you stand, or whether your current plan is protecting your vision and quality of life in the long run, a structured consultation can help bring clarity.
Good care starts with understanding, not alarm.
If you’ve been advised treatment, surgery, or long-term monitoring and would like to understand the reasoning- including what happens if you wait- I’m happy to walk you through it. And if you would like to discuss what this means for your eyes, over time, you’re welcome to schedule a consultation.

Frequently Asked Questions: Glaucoma Care
What is glaucoma and why is it called the silent thief of sight?
Glaucoma is a disease of the optic nerve, the nerve that carries visual information from the eye to the brain. It causes permanent damage slowly and silently. There is no pain, redness, or early warning signal. By the time most patients notice something is wrong, significant damage has already occurred. This is why early detection matters so much. Waiting for symptoms is not a safe strategy in glaucoma.
Can glaucoma be cured?
No. Glaucoma cannot be cured, and damage already done to the optic nerve cannot be reversed. But with early detection and the right treatment, progression can be slowed significantly, often to the point where it never affects daily life. The goal of glaucoma care is to protect the vision and quality of life you have, for as long as possible.
What is target eye pressure in glaucoma?
Target eye pressure is the pressure level at which glaucoma progression is slow enough that it is unlikely to affect your quality of life during your lifetime. It is not a fixed number. It is personalised, based on how much damage already exists, how fast the disease is moving, your age, and your life expectancy. Good glaucoma care is not about hitting a target on paper. It is about protecting the optic nerve over decades.
How is glaucoma different from simply having high eye pressure?
Not all glaucoma is caused by high eye pressure, and not all high eye pressure means glaucoma. Normal tension glaucoma damages the optic nerve even at statistically normal pressure levels. Some people have elevated pressure for years without developing glaucoma at all. This is why a pressure check alone is not enough. A proper glaucoma evaluation includes optic nerve examination, OCT imaging, visual field testing, and corneal thickness measurement.
What does stepwise glaucoma treatment mean?
Glaucoma treatment is not a single decision. It evolves over time. Medication, laser, and surgery are tools used at different points along the disease timeline — not competing options. The approach starts with the least intervention required to protect the nerve and adjusts as the disease changes. Every treatment decision carries long-term implications. The question is never just “Can we do something?” It is always “What best protects this eye, and this person’s life, over time?”
When is glaucoma surgery necessary?
Surgery is recommended when glaucoma continues to progress despite appropriate treatment, when structural damage is advancing, or when remaining vision needs stronger protection than drops or laser can provide. At that point, surgery is not an aggressive choice. It becomes the most conservative one. The decision is based on long-term risk to vision, not just today’s pressure reading.
Who needs a glaucoma specialist rather than a general eye doctor?
You should see a glaucoma specialist if glaucoma has been diagnosed or is suspected, if you have a strong family history of glaucoma, if your optic nerve looks unusual on routine examination, if you are on multiple glaucoma drops without adequate control, if surgery has been recommended, or if you want an independent second opinion on your current plan. Glaucoma is a lifelong condition. It benefits from long-arc thinking, not episodic care.
What does a glaucoma second opinion involve?
A structured glaucoma second opinion reviews your diagnosis, current treatment, and all available progression data independently. It is not about finding fault with your existing doctor. It is about making sure your long-term plan is the strongest it can be. Bring all previous reports: OCT scans, visual fields, pressure records, and prescription history. The more longitudinal data available, the more useful the assessment.
A structured review typically includes: Report interpretation, Risk assessment, Progression evaluation, Treatment necessity review, and a Long-term strategy discussion
Second opinions are not about changing doctors. They are about improving decision clarity.
Can glaucoma affect both eyes equally?
Not always. Glaucoma frequently affects one eye more than the other, and the rate of progression can differ between eyes. This is one reason why monitoring each eye individually, with separate visual field tests and OCT scans, is important. Treatment decisions are made eye by eye, not as a single plan for both.
What happens if I stop my glaucoma drops?
Eye pressure rises when drops are stopped. The optic nerve may sustain further damage, silently, without any symptoms. Glaucoma does not pause because treatment does. Never stop glaucoma medication without discussing it with your doctor first. If cost, side effects, or difficulty with the regimen are the issue, there are often alternatives worth exploring.
