Abstract Details


Persistan pupillary membrane (PPM) is managed with pharmacologic therapy, laser treatments, and surgery to clear the visual axis and optimize visual development. We presented our visual and anatomic outcomes of a surgical removal in 5 eyes.


Yuzuncu Yil University Medical School Ophthalmology Department


Five eyes of 3 patients with PPM which treated surgically were included in the study. Each PPM was judged to be visually significant based on poor visual acuity, poor retinoscopic reflex, or inability to visualize the fundus. The surgical technique included injection of a viscoelastic agent beneath the pupillary strands to bow the manteriorly, careful peeling of residual adherent strands from the anterior lens capsule, and lysis of the strands at the pupillary magrin with intraocular scissors. Pre- and postoperative visual (Snellen) acuity and examinations were recorded.


First patient was 6 years old girl with PPM in left eye. Follow up time was 25 months after surgery.Best corrected visual acuities(BCVA) were 0.05 preoperatively and 0.4 (-2.00x165ͦ) postoperatively. Second patient was 5 years old boy with PPM in both eyes. Follow up time was 14 months after surgery. BCVA were 0.05 preoperatively and 0.6 (-3.00x10ͦ) postoperatively in right eye. In left eye BCVA were 2 meter count fingers preoperatively and 0.1 (-7.00 -3.50x175ͦ) postoperatively. Third patient was 4 years old girl with PPM in both eyes. Follow up time was 7 months after surgery. BCVA were 0.6 preoperatively and 0.6 (+4.25) postoperatively in both eyes.


There were no intraoperative complications. Allpatients had successful clearance of the visual axis and good visual acuity.
