- Gradual loss of peripheral (side) vision
- Tunnel vision in advanced stages
- Eye pain or pressure (in acute cases)
- Nausea and vomiting (in acute angle-closure)
- Blurred vision
- Seeing rainbow-coloured halos around lights

About Glaucoma
Understanding Glaucoma
Glaucoma is a group of progressive eye diseases characterized by damage to the optic nerve, which transmits visual signals from the retina to the brain. In most cases, this nerve damage is closely linked to increased intraocular pressure (IOP), which occurs when the fluid inside the front part of the eye (aqueous humor) fails to circulate or drain properly.
Often referred to as the "silent thief of sight," open-angle glaucoma develops gradually and painlessly without early warning signs. Peripheral vision is typically lost first, meaning significant and irreversible vision loss can occur before a person notices any change. Conversely, acute angle-closure glaucoma is a medical emergency caused by a rapid blockage of drainage canals, causing intense eye pain, sudden blurred vision, and nausea.
Key Risk Factors
- Age 40 and older
- Family history of glaucoma
- Elevated intraocular pressure
- High myopia or hyperopia
- Systemic conditions such as diabetes and hypertension
- Prolonged use of corticosteroid medications
