Retinal Functions in Dominant Cystoid Macular Dystrophy (Dcmd)

Abstract

Dominant cystoid macular dystrophy (DCMD) occurred in 28 members of 5 unrelated families. The disease is characterized by cystoid macular oedema and leakage from retinal capillaries in the posterior pole. Colour vision examination reveals a type I red-green defect with concomitant blue-yellow defectiveness; the latter may be caused by the leaking capillaries. The ERG is normal. The EOG is subnormal. Darkadaptation curves are often slightly disturbed. There are frequently also aspecific pigmentary alterations in the peripheral fundus.
