Choroidal dystrophies

Definition

Choroidal dystrophy is an eye disorder involving a layer of blood vessels between the sclera and retina called the choroid.

In most cases, choroidal dystrophy is due to an abnormal gene, which is passed down through families. It most often affects males, starting in childhood.

The first symptoms are peripheral vision loss and vision loss at night. An eye surgeon who specializes in the back of the eye (retina specialist) can diagnose this disorder.

Alternative Names

Choroideremia; Gyrate atrophy; Central areolar choroidal dystrophy
