Abstract

Typical retinitis pigmentosa (RP) may not be the only retinal phenotype encountered in ataxia with vitamin E deficiency (AVED). The following short case series describes a novel form of retinopathy in AVED. We describe two patients with AVED belonging to the same consanguineous sibship. Both presented an unusual retinopathy consisting of scattered, multifocal, nummular, hyperautofluorescent atrophic retinal patches. The retinopathy remained stable under vitamin E supplementation. We hypothesize these changes to be the result of arrested AVED-related RP following early supplementation with α-tocopherol acetate.
