Epithelial downgrowth is a condition in which corneal or conjunctival epithelial cells are introduced into the eye by penetrating trauma or surgery. An epithelial membrane then grows over the internal structures of the eye and can often be visible as a translucent membrane growing over the corneal endothelium.
This patient had an intracapsular cataract extraction performed in the past and a recent secondary anterior chamber intraocular lens placed. She subsequently developed elevated intraocular pressure secondary to epithelial downgrowth, visible here as a faint membrane over her superior cornea. The demarcation of this membrane and the diffuse microcystic edema of the cornea can be more easily seen on the retroillumination photograph.
