May 18 2020 by McGill University Health Centre

A Mooren ulcer is a rapidly progressive ulcerative keratitis that first affects the periphery of the cornea before spreading circumferentially toward its center. Mooren ulcer is a diagnosis of exclusion: it can only be diagnosed after ruling out infectious and systemic causes. In this enucleation specimen, the periphery of the cornea is circumferentially ulcerated (arrow) and the cornea is thinning. There is also scarring of the corneoscleral junction.

Condition/keywords: Mooren's ulcer, ulcerative keratitis
