  • Abstract
  • Look Inside

A 6-year-old girl sought medical advice with night blindness as chief complaint. We detected marked elevation of threshold for dark adaptation, constriction of peripheral visual field and impaired visual acuity in both eyes. We observed, fundus-copically, numerous small white dots in both eyes. The spots were either discrete or coalescent. Panel D 15 test showed mild tritanomaly.

Essentially identical findings were seen in her sister aged 7 years. Both cases showed reduced ERG. During the follow-up period of two years, both cases showed progression of the disease, both funduscopically and functionally. the EOG light rise became gradually abnormal during the 2 years. We diagnosed the cases as retinitis punctata albescens. Family history was compatible with autosomal recessive pattern.
