Long-term follow-up of the physiologic abnormalities and fundus changes in fundus albipunctatus.

Fundus albipunctatus (FA) is considered to be a congenital stationary night-blinding disorder, but there has been no electrophysiologic or photographic documentation of long stability or change. This documentation is presented for two cases followed for 13 to 14 years. The physiologic (functional) deficits appeared to be stable, in support of the concept that FA is not a progressive dystrophy. However, the fundus lesions evolved in appearance from flecks in childhood to relatively permanent punctate dots that increase in number over the years.
