Glaucoma

Causes
Glaucoma is a leading cause of blindness in the United States. It typically affects people over the age of forty. The early signs may occur when the passages that filter and exchange fluid from within the eye become blocked, causing the internal eye pressure to increase. Undiagnosed and untreated, this increased pressure may cause permanent damage to the optic nerve. The chances of developing glaucoma are increased when there is a family history of the disease, or when an individual is of African descent, very nearsighted, or has diabetes.

Symptoms
Glaucoma tends to develop gradually and without symptoms. If there are symptoms, they may include minor blurring of vision, loss of central or peripheral vision, the appearance of colored rings around lights, and eye pain or dull headaches.

Diagnosis and Treatment
Glaucoma cannot be prevented, but it can, in most cases, be controlled. A comprehensive eye exam can detect the onset of signs and symptoms of glaucoma. Your eye care specialist will do further testing and may prescribe medication to control the pressure inside the eye or recommend other forms of treatment, including laser or conventional surgery.
