Reticular dystrophy of the retinal pigment epithelium. A clinical and electrophysiologic study of three generations.

Reticular dystrophy of the retinal pigment epithelium is characterized by a posterior pattern of pigment clumping like a "fishnet with knots." Four patients in three successive generations were seen with typical reticular dystrophy. A fifth patient had abnormal dark adaptation. In this family reticular dystrophy was characterized by the typical reticular pigmentary pattern, good visual acuity, normal electroretinographic findings, abnormal electro-oculographic findings, and abnormal dark adaptation. The pedigree indicates autosomal dominance as the inheritance pattern.
