- Explain protecting the remaining vision.
Who is at risk and how it is detected
Risk increases with age, a family history of glaucoma, elevated eye pressure, and certain ancestries, including African and Hispanic heritage. Diabetes and severe nearsightedness also raise risk. A complete eye examination measures eye pressure, inspects the drainage angle, examines the optic nerve after dilating the pupil, and tests the visual field. These painless tests can detect glaucoma before symptoms appear.
Protecting the remaining vision
Treatment cannot restore vision already lost, but it can usually stop or slow further damage. Daily prescription eye drops that lower eye pressure are the most common first treatment. Laser procedures and surgery improve fluid drainage when drops are not enough. Taking drops exactly as prescribed and keeping follow-up appointments are essential, because glaucoma is controlled rather than cured and damage continues silently if pressure stays high.
Key concepts
- Damage to the optic nerve
- Glaucoma is a group of diseases that damage the optic nerve, the cable that carries visual information from the eye to the brain.
- A silent disease with few warning signs
- Open-angle glaucoma usually causes no symptoms in its early stages: no pain, no redness, and no obvious change in vision.
- Who is at risk and how it is detected
- Risk increases with age, a family history of glaucoma, elevated eye pressure, and certain ancestries, including African and Hispanic heritage.
- Protecting the remaining vision
- Treatment cannot restore vision already lost, but it can usually stop or slow further damage.
