Glaucoma is a debilitating set of eye diseases that often occur without any symptoms.
Common types of glaucoma
There are warning signs, though, that might indicate you have or are developing some form of glaucoma.
Click the tabs below for information on common types of glaucoma.
- Occurs when the eye's drainage passage is blocked
- Unlike open-angle glaucoma (see tab below), this type of glaucoma develops quickly
- Symptoms include intense pain, nausea, redness of the eye and blurred vision
- Affects children who are born with a defect in the drainage passage
- Symptoms include watery and cloudy eyes and sensitivity to light
- Surgery is often performed to treat this form of glaucoma
- Leads to damage of the optic nerve and narrowed peripheral vision
- Eye pressure remains normal
- It is unknown why this type of glaucoma develops
- Occurs when new blood vessels grow on the iris, which can block the flow of fluid from the eye
- The most common type of glaucoma
- Develops when fluid inside the eye drains too slowly, eye pressure rises and the pressure damages the optic nerve
- This condition can go unnoticed for years
Other things to know about possible glaucoma symptoms:
- Low blood pressure can lead to optic nerve damage. When blood pressure drops too low, the optic nerve doesn't receive enough blood.
- People with diabetes are twice as likely to develop glaucoma. In addition, people with open-angle glaucoma are more likely to develop diabetes than those who don't have glaucoma.
- High eye pressure doesn't necessarily mean you will develop glaucoma. As a precaution, have your eyes checked annually.
