While some patients may experience symptoms from glaucoma as the disease progresses, others do not learn they have the condition until they undergo a routine eye exam. There are several different exams performed to diagnose glaucoma, including a visual field and visual acuity test. These tests measure peripheral vision and how well patients can see at various distances. Other tests may also be performed, such as tonometry to measure the pressure inside the eye and pachymetry to measure the thickness of the cornea, and optic nerve scans to evaluate the health of the nerve.
Treatment For Glaucoma
Once glaucoma has been diagnosed, treatment should begin as soon as possible to help minimize the risk of permanent vision loss. There is no cure for glaucoma, so treatment focuses on relieving symptoms and preventing further damage from occurring. Most cases of glaucoma can be treated with eye drops, laser surgery or microsurgery. The best treatment for your individual case depends on the type and severity of the disease, and can be discussed with your doctor.
Eye drops are used to reduce fluid production in the front of the eye or to help drain excess fluid, but can lead to redness, stinging, irritation or blurry vision. Patients should tell their doctor about any drug reactions to minimize the risk of side effects.
Laser surgery for glaucoma aims to increase the outflow of fluid from the eye or eliminate fluid blockages (such as laser trabeculoplasty, iridotomy and cyclophotocoagulation.)
While there are no surefire ways to prevent glaucoma from developing, regular screenings and early detection are the best forms of protection against the harmful damage that the disease can cause. While anyone can develop glaucoma, some people are at a higher risk for developing disease. These people may include those who:
- Are over the age of 60
- African Americans over the age of 40
- Have a family history of glaucoma
- Have poor vision
- Have diabetes
Patients should have a comprehensive, dilated eye exam at least once every two years, especially if they have a higher risk of developing glaucoma. Older patients may be encouraged to be tested more frequently.
