What Is Glaucoma?
There are several types of glaucoma.
Open-angle glaucoma is the most common form of the disease and can cause damage to your optic nerve before you start to notice symptoms. This disease can start developing when you either have too much fluid (aqueous humor) in the anterior part of your eye or if not enough fluid is draining.
Too much fluid in your eye can increase your IOP levels, damaging your optic nerve and possibly leading to vision loss. Our doctors can diagnose glaucoma by measuring your IOP levels with a tonometer or observing your optic nerve during a comprehensive eye exam.
Closed-angle, or angle-closure, glaucoma is a type of the disease that can occur very rapidly, causing pain, headaches, nausea, and vision loss.
This type of glaucoma occurs when the drainage angle between your iris and cornea closes, preventing any fluids from draining properly. This can result in rapidly rising IOP levels and vision loss. Closed-angle glaucoma is considered to be a medical emergency that requires immediate attention.
