Risk factors Risk increases with age, family history, elevated eye pressure, diabetes, steroid use, previous eye injury and certain anatomical features.
Testing Diagnosis requires more than measuring pressure. A complete evaluation may include optic-nerve examination, visual-field testing, corneal thickness measurement, drainage-angle assessment and OCT imaging.
Treatment Treatment may include pressure-lowering drops, laser procedures or surgery. Lost vision usually cannot be restored, so adherence and follow-up are essential.
Urgent symptoms Sudden severe eye pain, headache, halos, nausea and blurred vision can indicate acute angle closure and require emergency care.
Frequently Asked Questions
Can glaucoma exist with normal eye pressure?
Yes. Optic-nerve damage can occur even when pressure readings are within the usual range.
Is glaucoma curable?
It is usually controlled rather than cured.
Can treatment restore lost vision?
Generally no; treatment aims to prevent further loss.
Who needs regular screening?
People with risk factors such as age, family history, diabetes or steroid exposure.
