Educational content only
This page is general patient education, not medical advice. It does not diagnose conditions, recommend specific treatments for you, or replace a conversation with your eye care provider. Always consult a qualified clinician before making decisions about your eye health.
Glaucoma damages your optic nerve — usually before you notice anything is wrong. The good news: when caught early, it's highly manageable, and most patients keep their vision for life.
What's happening
Pressure builds. The nerve suffers.
Your eye constantly makes a clear fluid that nourishes the front of the eye. Normally it drains out at the same rate — like water through a sink.
In glaucoma, that drain gets clogged or narrowed. Fluid backs up. Pressure rises. Over time, this pressure slowly damages the optic nerve — the cable that sends images from your eye to your brain.
Progression
How glaucoma changes over time.
Stage 01
Healthy vision
Full field of view, crisp peripheral detail.
Stage 02
Early
Subtle blind spots may be present. Usually unnoticed.
Stage 03
Moderate
Tunnel vision begins. Bumping into objects.
Stage 04
Advanced
Only a small central area remains.
What helps
Here's the plan — and why it works.
First line
Prescription eye drops
Used daily, these lower eye pressure by either reducing fluid production or improving drainage.
In-office
Selective laser (SLT)
A quick, painless laser opens up the eye's drainage system. 10 minutes. Results typically last 2–3 years, sometimes longer — and SLT can be repeated.
Surgical
Minimally invasive (MIGS)
Tiny devices — smaller than an eyelash — help fluid drain. Often combined with cataract surgery.
Advanced
Traditional surgery
For advanced cases, procedures like trabeculectomy create a new drainage path.
When to call us immediately
Sudden severe eye pain, nausea with eye pain, blurred vision with halos around lights, or a red eye with vision loss could mean acute angle-closure glaucoma — a medical emergency.
Common questions
Honest answers to common questions.
Will I go blind from glaucoma?+
For the vast majority of patients — especially when caught early — no. When diagnosed and treated early, most people keep their useful vision for life. The key is using your drops consistently and keeping your follow-up appointments.
Can glaucoma be cured?+
Not yet — but it's highly manageable. Think of it like high blood pressure: you don't cure it, you control it. Once pressure is stabilized, many patients live decades without further vision loss.
What if I forget a dose of drops?+
Take it as soon as you remember — unless it's almost time for your next dose. Don't double up. One missed dose won't cause harm, but repeated misses let pressure climb back up.
Does glaucoma hurt?+
Usually not — that's why it's called the 'silent thief.' Most forms cause no pain or obvious symptoms until significant damage has occurred. The exception is acute angle-closure glaucoma, which is very painful and a medical emergency.
Can I still drive, read, and work normally?+
In early and moderate stages, absolutely. Even in later stages, most patients retain enough central vision for daily activities. If anything changes, we'll discuss it directly.
