Health Condition

Glaucoma

About This Condition

The term glaucoma describes a group of eye conditions that are usually associated with increased intraocular pressure (pressure within the eyeball).

In many cases, the cause of glaucoma is unknown. Conventional medications are frequently effective in reducing intraocular pressure. Therefore, it is important for people with glaucoma to be under the care of an ophthalmologist.

Symptoms

Because glaucoma may not cause any symptoms until it has reached an advanced and irreversible stage, regular eye exams are recommended, especially after age 40. In the later stages, symptoms include loss of peripheral (side) vision, blurred vision, blind spots, seeing halos around lights, and poor night vision. If left untreated, glaucoma may cause blindness.

Other Therapies

Surgical procedures, such as laser trabeculoplasty and trabeculectomy, can increase fluid drainage from the eye to relieve pressure.
