Frequently asked questions
Can glaucoma happen without symptoms?
Often yes. Chronic glaucoma may steal side vision gradually without pain. Regular pressure checks and optic nerve assessment help find it early.
Is glaucoma only about high eye pressure?
Pressure is a major risk factor, but some people develop glaucoma with apparently normal pressure. Optic nerve appearance and visual field tests guide diagnosis.
What are the symptoms of acute glaucoma?
Severe eye pain, headache, blurred vision, halos around lights, nausea and a red eye can signal acute angle-closure glaucoma — seek emergency care immediately.
