Surgical treatment of congenital persistent pupillary membrane

Abstract

Objective To investigate the operation and effects of the removal of congenital persistent pupillary membrane using intraocular micro instruments. Methods 7 patients (10 eyes) with congenital persistent pupillary membrane received surgery. During operation, the persistent pupillary membrane was cut off from its junction with the iris following the maintaining of the anterior chamber with viscoelastic agent, and then the membrane was clipped out with intraocular micro forceps. Pupil, visual acuity (VA) and complications post-surgery were observed. Results The persistent pupillary membranes were removed from 10 eyes (100%) successfully. The pupils were round, the light reflex was sensitive, and the VA improved in different degrees in the patients who could cooperate with the VA examination post-surgery. No complications such as lens injury and anterior chamber hemorrhage occurred. Conclusions The operation of removal of congenital persistent pupillary membrane using intraocular micro instruments has the advantages of small incision, high safety, less complications and so on. It is an ideal operation method. Key words: Congenital; Persistent pupillary membrane; Surgery
