RETINAL DYSTROPHIES AND SYNDROMES
Retinitis Punctata Albescens
Retinitis punctata albescens is a progressive retinal degeneration characterized by multiple white spots at the level of the retinal pigment epithelium scattered in the mid-periphery. It is a variant of retinitis pigmentosa, with pigmentary changes absent and attenuated vessels. The condition is usually stationary or very slowly progressive.
Symptoms include night blindness, constriction of visual field, and alterations in color perception. Another finding is a severely depressed electroretinogram (ERG) that does not recover with dark adaptation.
