Pattern dystrophies of the retinal pigment epithelium. The study of three generations in a family.

Three members of a family in one generation were affected by a pattern dystrophy of the retinal pigment epithelium. The patients present typical hyperpigmented macular RPE lesions in a butterfly-shaped to (macro-)reticular pattern, and were all asymptomatic. Examination of 26 family members in 3 generations suggests autosomal recessive inheritance. The family showed some cases of congenital deutanomaly, and a female subject presented both disorders.
