Quick answer

Glaucoma is usually a slow, silent condition that damages the optic nerve, often linked to raised eye pressure. Screening matters because peripheral vision can be lost before you notice. Acute glaucoma is different — sudden pain, halos and nausea need emergency care.

## 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.
