Abstract

Persistence of a pupillary membrane is due to incomplete atrophy (resorption) of the fetal vascular arcades and associated mesodermal tissue derived from the primitive annular vessel. It is one of the most common; albeit usually clinically innocuous; congenital malformations of the eye. C< i genital pupillary membranes always arise at the collarette. Total persistence of the pupillary membrane is extremely rare and usually associated with other ocular anomalies; especially microphthalmos. The author describe a 15 year old female patient with amblyopia (0. D.) secondary to an extensive; bilateral persistence of the pupillary membrane unassociated with any other ocular anomaly; who received successful surgical removal.
