  • Abstract
  • Look Inside

Clinical and clectroretinographical follow-up was conducted in 5 cases with primary pigment degeneration of the retina for periods ranging from 3 to 7 years. The 5 cases consisted of 4(7 eyes) in whom visual acuity and peripheral visual field were well retained with merely subnormal ERG and another one (1 eye)in whom clinical features were moderately advanced with negative ERG response.

1. One case showed gradual constriction of peripheral visual field and the other an enlarge-ment of ring-shaped scotoma during the five years of observation.
