Purpose: To report epithelial downgrowth following goniotomy.
Design: Observational case report.
Methods: Surgical management of a child with congenital glaucoma and epithelial downgrowth.
Results: One year after nasal goniotomy and multiple Ahmed valve revisions an epithelial inclusion cyst was noted adjacent to the clear corneal goniotomy incision. Ab externo drainage and limbal cryotherapy were required twice for recurrent growth of the cyst. Six months after the second treatment the eye remains cyst-free.
Conclusions: Epithelial downgrowth is a rare complication of surgery for glaucoma, but because of its potential to threaten sight it should always be considered as a possible complication.
