We report 3 siblings from a nonconsanguineous white family with bilateral persistent pupillary membranes with dissimilar forms of severity. Two of the patients required no treatment; 1 was treated surgically for occlusion of the pupillary axis and moderate visual acuity decrease. Anterior segment examination was otherwise normal in the siblings. Although persistent pupillary membranes are usually sporadic, cases in which they are associated with other anterior chamber abnormalities might be inherited autosomal dominant. To our knowledge, this is the first report of a familial isolated persistent papillary membrane case with no other anterior chamber abnormality.
