[Pigmented paravenous retino-choroidal atrophy (author's transl)].

A 22-year-old man presented a typical appearance of pigmented paravenous retino-choroidal atrophy. Fluorescein angiography demonstrated a profound loss of the choriocapillaris in the affected areas. The amplitude of the scotopic and photopic electroretinogramme response was reduced. The electro-oculographic light rise was normal.
