Be Eye Wise and learn that glaucoma is an eye condition where pressure builds up in the eye because fluids are not draining properly. This pressure can damage the eye’s optic nerve, eventually causing vision loss.
There are several types of glaucoma.
Open-angle glaucoma occurs when ocular fluid cannot pass through the eye’s filtration system (trabecular meshwork) to the drainage canals.
Angle-closure glaucoma occurs when the drainage canals are blocked. It can progress chronically or acutely.
Low-tension glaucoma occurs when a patient with normal-range pressures experiences optic nerve damage.
Childhood glaucoma begins in infancy, childhood or adolescence and includes congenital glaucoma.
Symptoms of glaucoma can be:
- Vision loss.
- Small blind spots.
- Tunnel vision.
- Blurred vision.
- Severe eye pain.
- Halos or rainbows around light.
- Nausea and vomiting.
Causes of glaucoma can be:
- Elevated intraocular pressure.
- Family history of glaucoma.
- Abnormal optic nerve anatomy.
- Are over age 40.
- African or Asian descent.
- High degrees of myopia.
