A patient with bilateral persistent pupillary membrane: a conservative approach.

The author describes the case of a girl with bilateral persistent pupillary membranes and good visual acuity. An otherwise healthy 10-year-old girl presented with persistent pupillary membranes in both eyes since childhood. The patient had ametropic amblyopia, which was treated with spectacles and part-time occlusion therapy, with the patient responding conventionally. After therapy, her best-corrected visual acuity was 20/25 in both eyes. She had stereopsis of 50 seconds of arc, orthophoria, and normal extraocular movements. The remainder of the examination was normal. Patients with bilateral persistent pupillary membranes may not require surgery if there is adequate opening. The author suggests a trial of refractive correction and occlusion therapy before deciding on surgical and laser intervention, even if it seems an absolute requirement.
