[Retinitis pigmentosa, vitiligo and deaf-mutism. Apropos of a case]

Abstract

The paper presents the observation of a 47 year-old patient with pigmentary retinopathy, hypoacousy, and vitiligo. The retinopathy and hypoacousy were associated in 10% of the cases. There is a certain parallelism between the degeneration of the retineal epithelium and the Corti neurosensorial epithelium. The association with vitiligo is only rarely mentioned in the literature. The extension of the abiotrophic process at the level of the cutaneous melanocytes may be explained by the variable expressivity of the pathological gene with the affection of different diencefalic nervous centers.
