Abstract

PURPOSE: To report a case of an anterior fibrovascular membrane following cataract extraction and intraocular lens implantation in a patient with congenital aniridia.
CASE SUMMARY
A 13-year-old girl presented with congenital aniridia and cataracts in both eyes. She underwent cataract extraction by phacoemulcification with intraocular lens implantation. Six months after cataract surgery, a progressive anterior chamber fibrovascular membrane was noted in both intraocular lens and rudimentary iris. Surgical excision of the fibrovascular membrane was performed, but there was recurrence after five weeks in both eyes. Subsequent surgical intervention on both eyes involved intraocular lens explantation combined with membranectomy to prevent recurrence and phthisis. Surgical findings indicated that the fibrovascular membrane involved the retrolenticular space, and histopathological evidence indicated that the extensive fibrotic tissue originated from the root of the rudimentary iris.
CONCLUSIONS
Patients with congenital aniridia should be monitored carefully for the development of intraocular fibrosis after intraocular lens implantation. If a fibrovascular membrane is noted, early surgical intervention is recommended, and the explantation of the intraocular lens should be considered during surgical intervention to prevent recurrence and complications.
