Sequential argon-YAG laser membranotomy of extensive persistent pupillary membrane with visual loss

A 20-year-old woman, a registered nurse, presented with best-corrected visual acuity of 6/15 (20/50) due to bilateral extensive persistent pupillary membrane. Sequential argon laser photocoagulation of the iris strands at the pupillary membrane iris collarette followed by neodymium:YAG laser lysis resulted in partial clearing of the central visual axis without bleeding. Best-corrected visual acuity improved to 6/9 (20/30) bilaterally without complications noted 1 year after combined laser therapy.
