Glaucoma is a leading cause of blindness in the U.S. It occurs when the pressure inside the eye rises, damaging the optic nerve and causing vision loss. The condition often develops over many years without causing pain or other noticeable symptoms - so you may not experience vision loss until the disease has progressed.
Symptoms that you could be developing glaucoma include blurred vision, loss of peripheral vision, halo effects around lights, and painful or reddened eyes. People at high risk include those who are over the age of 40, diabetic, near-sighted, African-American, or who have a family history of glaucoma.
To detect glaucoma, Dr. Nancy Chen, MD will test your visual acuity and visual field as well as the pressure in your eye. Regular eye exams help to monitor the changes in your eyesight and to determine whether you may develop glaucoma.
Once diagnosed, glaucoma can be controlled. Treatments to lower pressure in the eye include non-surgical methods such as prescription eye drops and medications, laser therapy, and surgery.
