Purpose: The purpose of this study was to describe the clinical features and management of fibrovascular pupillary membrane.
Methods: Four patients with congenital fibrovascular pupillary membrane were recruited. Comprehensively, ophthalmic examinations were performed. Peripheral iridectomy was performed to create a tunnel for blunt dissection of adhesion between the membrane and the lens capsule. Bipolar radiofrequency diathermy was then used to cut the membrane utilizing its coagulation effect.
Results: All four patients received uneventful membranectomy surgeries. The follow-up duration ranged from 9 to 16 months. All patients recovered well. Visual behavior was central and steady. The natural pupil size ranged from 2 to 3 mm. No sign of visual axis obstruction, cataract formation, or intraocular pressure elevation was detected during the follow-up. No second surgery was needed for all patients.
Conclusion: Fibrovascular pupillary membrane is a rare unilateral disease impairing visual acuity in children. Using the technique combining peripheral iridectomy with bipolar radiofrequency, diathermy can simplify the traditional surgery procedures and reduce the risks when removing fibrovascular pupillary membranes.
