This 36 year old man first noticed constricted visual fields at age 6 when he began bumping into things. He was also felt to be "uncoordinated" as a child and had an abnormal gait.

The clinical features supporting the diagnosis of retinitis pigmentosa with ataxia in this patient include: constricted visual fields; night blindness; bone-spicule-like pigmentation and narrowed arterioles on ophthalmoscopy; photoreceptor loss on OCT; a wide-based gait, absent proprioception and vibration sense in his fingers and toes; and, normally sighted parents.
