Epithelial downgrowth is a rare but feared complication of intraocular surgery or penetrating globe trauma, characterized by the intraocular migration of epithelial cells. Despite treatment, epithelial downgrowth can lead to endothelial decompensation, angle-closure glaucoma, intractable pain, and tractional retinal detachment.1 Reported treatments include membrane peel, argon laser, excision of affected intraocular structures, and fluorouracil injection.2 Despite this, more than 50% of patients with epithelial downgrowth undergo enucleation.1
