A glaucoma diagnosis can feel overwhelming, but the first 90 days are crucial for understanding your condition, starting treatment, and establishing a plan to protect your vision long term. Early follow-up, regular eye pressure monitoring, and clear communication with your glaucoma specialist can make a significant difference in preserving sight.
Your First 90 Days With Glaucoma: A Step-by-Step Action Plan
Many patients ask me: I have been diagnosed with glaucoma. What do I do now. Here is what I tell them: A glaucoma diagnosis does not mean you are going blind. It means you now have information most people get too late. The next 90 days are the most important window — not because the disease moves fast, but because the habits you build now protect your vision for the next 30 years.
This guide, written by Dr Shibal Bhartiya, tells you exactly what to do, in order.

Day 1–7 of Glaucoma Diagnosis: Get the Basics Right
Learn to put in your eye drops correctly
This is the single most important skill you will learn. Studies show that over 60% of patients use eye drops incorrectly — and incorrect technique means the drop misses the eye, or drains immediately into the tear duct and does nothing.
Wash your hands. Tilt your head back. Pull your lower eyelid gently down to form a pocket. Hold the bottle above the eye without touching it. Squeeze one drop into the pocket — not onto the eyeball directly. Close your eye gently. Press the inner corner of your eye (near the nose) firmly with one finger for 60 seconds. This blocks the tear duct and keeps the drug in the eye where it belongs. Do not blink vigorously. Do not wipe.
If you use more than one drop type, wait five minutes between them. The first drop dilutes and flushes out the second if you use them together.
Ask your doctor or optometrist to watch you do it once. Ask for a correction if your technique needs adjustment.
Here’s a video demostration:
Set your alarms — and take them seriously
Glaucoma drops work only when taken on time, every day, for life. A single missed day matters less than a pattern of casual delays.
Most drops are once daily, ideally at night. Set a recurring alarm on your phone with a label — “Left eye drop, right eye drop, press corner.” Place the bottle next to your toothbrush. The habit links to the existing habit.
If you use drops twice daily, set both alarms. Never rely on memory alone.
File your papers before they disappear
You walked out of the clinic with reports. Photograph or scan every one of them today — the visual field test, the OCT nerve scan, the IOP readings, the prescription. Put them in a dedicated folder on your phone or email them to yourself with the subject line “Glaucoma Records — [your name].”
You will need these at your next visit, at any second opinion, and if you travel and need emergency eye care. Doctors cannot make good decisions without your baseline.
Week 2–4 of Glaucoma Diagnosis: Build the Follow-Up Structure
Your 30-day appointment is not optional
Glaucoma drops take four to six weeks to show their full pressure-lowering effect. Your doctor needs to see you at 30 days to measure whether the drop is working — and to catch side effects early. Do not skip this.
At this visit, your doctor will check:
- Your intraocular pressure (IOP) against your baseline
- Whether the drop is causing redness, allergy, or discomfort
- Whether you need a dose adjustment or a switch to a different medication
Set a calendar reminder for this appointment the day you are diagnosed. If the appointment was not scheduled, call the clinic and schedule it yourself before the week is over.
Know what side effects to watch for
Most glaucoma drops are well-tolerated. But some cause changes you should know about.
Prostaglandin analogues (bimatoprost, travoprost, latanoprost) can darken the iris over time in some patients, and may cause eyelash growth or mild redness. These are cosmetic and not dangerous — but tell your doctor.
Beta-blockers (timolol) can slow your heart rate and cause breathlessness in patients with asthma or heart disease. If you feel unusually short of breath or very tired after starting drops, contact your doctor the same day.
Alpha agonists (brimonidine) sometimes cause an allergic reaction with marked redness and discharge, usually within weeks of starting. Stop the drop and call your doctor if this happens.
None of these mean you must stop treatment. They mean the treatment may need adjustment.
Month 1–2 of Glaucoma Diagnosis: Tell Your Family
Your siblings and children need an eye check — now
Glaucoma has a strong genetic component. First-degree relatives of a glaucoma patient have a four to nine times higher risk of developing the disease. Most of them will have no symptoms at all until damage is advanced.
Tell your siblings and adult children this week. Ask them to see an ophthalmologist for a baseline pressure check, optic nerve assessment, and field test. This is not alarmist. It is the most useful thing your diagnosis can do for your family.
Month 1–3: Address the Controllable Risk Factors
Stop smoking — this one is not negotiable
Smoking constricts blood vessels and reduces blood flow to the optic nerve. It worsens the vascular risk that many glaucoma patients already carry. The damage from smoking adds to the damage from pressure — and your nerve cannot absorb both.
If you smoke, speak to your doctor about cessation support. This is as important as the drops.
Get your metabolic parameters checked
High blood pressure, diabetes, thyroid disease, and sleep apnoea all affect glaucoma progression through vascular and metabolic pathways. If these are uncontrolled, your optic nerve faces risk from two directions simultaneously.
Ask your physician to check your blood pressure, fasting glucose, HbA1c, and thyroid function if these have not been done recently. If you snore heavily or feel exhausted in the mornings, mention it — untreated sleep apnoea is a recognised glaucoma risk factor that is almost always missed.
Exercise — the right kind
Moderate aerobic exercise (brisk walking 30 minutes, five days a week) lowers intraocular pressure by a clinically meaningful amount in most patients. Avoid high-resistance head-down exercises like heavy weightlifting or inverted yoga poses — these transiently spike IOP.
Month 2–3: Ask About Laser Treatment
SLT — Selective Laser Trabeculoplasty
If your glaucoma is open-angle type, your doctor may recommend SLT as a first-line treatment or as a supplement to drops. SLT uses a laser to improve fluid drainage from the eye. It is done in the clinic in five to ten minutes, is painless, and works in approximately 75 to 80% of patients.
The effect lasts three to five years and can be repeated. SLT does not burn tissue — it sends a gentle energy pulse that stimulates the drainage cells to work better.
Ask your doctor at the 30-day or 90-day visit: “Am I a candidate for SLT?”
LPI — Laser Peripheral Iridotomy
If your glaucoma is narrow-angle or angle-closure type, LPI is a preventive procedure that creates a small opening in the iris to prevent a sudden pressure spike (acute angle-closure attack). LPI is typically recommended before an attack happens — it takes three to four minutes per eye and prevents one of the most painful ophthalmic emergencies.
If your doctor mentioned narrow angles at any point, ask specifically whether you need LPI. Do not wait.
Throughout: Keep Your Perspective
Do not search the internet at 2am
Glaucoma outcomes in treated patients are overwhelmingly good. The disease moves slowly in the vast majority of cases. Patients who take their drops, attend follow-ups, and manage their risk factors maintain useful vision for life in most cases.
The stories of severe vision loss you will find online mostly involve patients who were never diagnosed, or who stopped treatment. You are neither.
Reach out if you need support
A new diagnosis changes how you think about your body. Some patients find this unsettling, and that is entirely normal. Several Indian and international glaucoma patient forums, and online communities run by ophthalmologists offer peer support from people at every stage of the same journey.
You do not have to figure this out alone.

Frequently Asked Questions
Do I have to take eye drops for life?
In most cases, yes. Glaucoma is a chronic condition and eye drops control pressure — they do not cure the disease. Stopping drops allows pressure to rise again and damage to resume. Some patients reduce or stop drops after successful laser treatment (SLT), but this is a decision made with your doctor based on your pressure readings, not independently.
What if I forget a drop one day?
Take it as soon as you remember, unless it is almost time for the next dose. Do not double up. One missed dose will not cause a crisis. A habit of casual misses will. Reset the alarm and continue.
Can I drive after putting in my eye drops?
Most glaucoma drops do not affect vision significantly. Some patients notice mild blurring for a few minutes immediately after instillation — wait for this to clear before driving. If your doctor has dilated your pupils at a clinic visit, do not drive until dilation wears off, typically three to four hours.
My pressure was normal at diagnosis. Do I still have glaucoma?
Yes — this is called normal-tension glaucoma (NTG). Roughly 30 to 40% of glaucoma patients in India have pressures within the statistical normal range. The diagnosis is made on optic nerve appearance and visual field changes, not pressure alone. NTG is treated the same way — the target is to lower pressure further from your individual baseline.
Is glaucoma hereditary? Do I need to tell my family?
Yes, and yes. First-degree relatives — parents, siblings, children — have a four to nine times higher risk. Most will have no symptoms. Tell them this week and ask them to see an ophthalmologist for a baseline check that includes pressure, nerve assessment, and a visual field test.
Will I go blind?
Treated glaucoma in a compliant patient who attends follow-up carries a very low risk of blindness. The risk is real only when the disease is undiagnosed, undertreated, or ignored. You have been diagnosed. That is the most important step already taken.
What is SLT and should I ask about it?
Selective Laser Trabeculoplasty (SLT) is a five-minute clinic procedure that improves fluid drainage from the eye. It works in approximately 75 to 80% of open-angle glaucoma patients and can reduce or eliminate the need for drops for three to five years. Ask your doctor at the 30-day visit whether you are a candidate.
Can I exercise with glaucoma?
Yes — moderate aerobic exercise is actively beneficial and lowers IOP. Brisk walking, cycling, and swimming are all good. Avoid heavy resistance training with breath-holding (Valsalva manoeuvre) and inverted positions, both of which spike pressure transiently. If exercise is a regular part of your routine, tell your doctor so they can factor it into your pressure readings.
My drops are making my eyes red. Should I stop?
Do not stop without speaking to your doctor first. Redness is common with several drop classes and is often manageable — a preservative-free formulation or a switch in medication resolves it in most cases. Stopping drops independently allows pressure to rise. Call the clinic and describe the symptom.
How often will I need follow-up forever?
Once stable on treatment, most patients are reviewed every three to six months. This includes a pressure check and, once yearly or more often if needed, a repeat visual field test and OCT nerve scan to confirm the disease is not progressing. Glaucoma never becomes self-managing — the follow-up rhythm continues for life, but it is not onerous once the initial titration phase is complete.
