Choroideremia; Gyrate atrophy; Central areolar choroidal dystrophy
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 retina (back of the eye) can diagnose this disorder.
Exams and Tests
The following tests may be needed to diagnose the condition:
