What is pigment dispersion?

Pigment dispersion syndrome is a condition that happens when pigment rubs off of the back of the iris of the eye when the fibers supporting the lens rub against it. This pigment is deposited in the trabecular meshwork of the eye, where the fluid drains out. This condition is more common in people that are nearsighted.

Up to 50 percent of people with this condition can develop elevated eye pressure and glaucoma if the pigment decreases the outflow of fluid. Your doctor will perform a careful exam of the lens after your pupils are dilated to detect the subtle signs of exfoliation. Remember that caring for your eyesight begins with complete eye examinations. A comprehensive evaluation is the best way to detect eye conditions such as glaucoma early, so that it can be addressed before it develops into something more serious.
