title: Epithelial downgrowth after Ahmed implantation presenting as a peritubular fibrovascular membrane.
abstract: This is a case report of a 54-year-old woman with chronic uveitis who developed epithelial downgrowth after an Ahmed valve implantation. The epithelial downgrowth presented in an unusual fashion, as a peritubular fibrovascular membrane. Our case suggests that in patients who have undergone glaucoma drainage implantation with clinical features such as persistent hypotony and atypical inflammatory cells, high clinical suspicion for epithelial downgrowth and careful search for potential fistulas are necessary, even without an obvious wound leak.
