Fundus albipunctatus and other flecked retina syndromes.
BACKGROUND
Several ophthalmic conditions manifest a flecked retina. Developing an understanding of their clinical presentations will enable the practitioner to most appropriately manage these conditions.


METHODS
A 27-year-old Middle Eastern woman manifested flecked retinas and nyctalopia. She had been given a diagnosis of retinitis punctata albescens, an inherited, progressive, night blindness; however, the medical history and clinical findings were not consistent with this disorder. Rather, they were consistent with fundus albipunctatus, an autosomal recessive, stationary, night blindness. The clinical presentation of fundus albipunctatus is characterized by discrete, white dots at the level of the retinal pigment epithelium and stable night blindness. A prolonged time for dark adaptation is required to produce normal amplitude electroretinograms in fundus albipunctatus as the result of a delay in the regeneration of rhodopsin. An electroretinogram administered after a prolonged dark adaptation time confirmed the diagnosis of stationary night blindness.


CONCLUSIONS
In order to ensure an accurate diagnosis for fundus albipunctatus, it is important to be aware of the clinical characteristics and appropriate electroretinogram protocol for this disorder.
