LETTER TO THE EDITOR Excision of Congenital Bilateral Persistent Pupillary Membrane in a Child with Exotropia.
OBJECTIVE
To report the clinical and histopathological findings of a patient who had bilateral persistent pupillary membrane with exotropia and high hyperopia.


METHODS



METHODS
A 7-year-old boy presented with a persistent pupillary membrane in both eyes. His best corrected visual acuity (BCVA) was 20/20 in the right eye and 20/32 in the left eye with exotropia of 18 prism diopters. He underwent surgical resection of both membranes. At 5 months postoperatively, BCVA was 20/20 with final bilateral refraction of +6.5 D in both eyes. Exotropia and photophobia showed improvement immediately after surgery. Histopathological examination revealed typical features of normal iris tissue in the excised membranes.


CONCLUSIONS
Bilateral persistent pupillary membranes were excised successfully without injury to other ocular tissues, including the crystalline lens. Surgical treatment may be required for the management of persistent pupillary membrane associated with visual impairment such as exotropia or photophobia.
