Early Detection Saves Sight
Glaucoma is often called the “sneak thief of sight” because most people don’t realize they have it until side vision is already lost. Here’s what every patient (and their family) should know.
No Symptoms at First
In chronic glaucoma, vision loss starts at the periphery (your side vision) while central vision remains clear until late stages. That’s why regular screening is essential after the age of 35–40.
Family History Matters
If a close relative (parent, sibling, or child) has glaucoma, your own risk increases four to ten-fold. All first-degree relatives should have periodic glaucoma testing.
Know the Risk Factors
- Elevated eye pressure
- Increasing age
- Short- or long-sightedness
- Past eye injury
- Steroid use (drops, tablets, inhalers, ointments)
How It’s Diagnosed
Tests include tonometry, gonioscopy, and fundus examination. If glaucoma is suspected, your doctor may also recommend perimetry (visual-field test), pachymetry (corneal thickness), and optic-nerve imaging.
Treatment and Follow-Up
There is no cure, but treatment can control eye pressure and prevent further loss. Options include:
- Eye drops (mainstay treatment)
- Laser procedures, such as Peripheral Iridotomy for angle-closure
- Surgery, including newer Minimally Invasive Glaucoma Surgery (MIGS) for selected cases
Treatment and monitoring are lifelong. Even after surgery, regular follow-ups every 3–6 months remain vital.
The Good News
When detected early and treated properly, blindness can be prevented. Regular check-ups and consistent medication are your best defence.
