  • Abstract
  • Look Inside

A pair of sisters, aged 11 and 13 years, manifested fundus features simulating fundus albipunctatus. No abnormalities were detected regarding visual acuity, visual field or color vision. While neither complained of night blindness, they showed ele-vated dark-adapted threshold and marked prolon-gation in dark adaptation time for the cone and rod. A delay in reaching the full amplitude of electroretinogram paralleled the delay in dark adaptation time. Funduscopy showed numerous spots in the retina, consisting of 1) discrete and yellow-white spots in the posterior fundus except the fovea, 2) dark-orange spots in the midperipher-al to the peripheral fundus, and 3) white spots in the fovea. The yellow-white spots in the first type were located anterior and posterior to the retinal vessels. Fluorescein angiography showed numerous tiny dots of hypo- and hyperfluorescence at the level of the retinal pigment epithelium. Above find-ings seemed to suggest that retinal lesions in fundus albipunctatus involved the superficial retinal layer and the retinal pigment epithelium.
