Glaucoma is often called the “silent thief of eyesight” because it develops slowly and usually shows no early symptoms. By the time vision problems appear, permanent damage may already have occurred.
What Is Glaucoma?
Glaucoma is a group of eye diseases in which the optic nerve gets damaged, most commonly due to increased pressure inside the eye. This damage usually begins with side (peripheral) vision loss and can eventually lead to blindness if not treated.
Who Should Be Most Cautious?
Doctors advise these people to be extra careful and get regular eye check-ups:
- People above 40 years of age – risk increases with age.
- Those with a family history of glaucoma – genetics play a major role.
- Diabetes and high blood pressure patients – poor blood flow affects the optic nerve.
- Long-term steroid users – steroid eye drops, inhalers, or tablets can raise eye pressure.
- People with high spectacle power – especially severe nearsightedness.
- Individuals with previous eye injury or surgery – trauma can trigger glaucoma.
- People with thin corneas – linked to higher glaucoma risk.
Early Warning Signs You Shouldn’t Ignore
- Gradual loss of side vision
- Blurred vision
- Seeing halos around lights
- Eye pain, headache, nausea, or vomiting (mainly in sudden glaucoma attacks)
⚠️ Important: Most glaucoma patients experience no pain or symptoms in the early stages.
How to Protect Your Eyesight
- Get a complete eye examination every 1–2 years
- Ensure testing of eye pressure, optic nerve, and visual field
- Avoid using steroid medicines without a doctor’s advice
- Keep blood sugar and blood pressure under control
Final Takeaway
Vision loss due to glaucoma is permanent, but early diagnosis can save your sight. If you are in a high-risk group, regular eye check-ups are essential—even if your vision feels normal.
