Pathophysiology and management of corneal sequestrum in cats

Corneal sequestrum is a common feline ocular condition, seen particularly in pure-bred and brachycephalic cats. It is characterised by corneal stromal necrosis with formation of dark, plaque-like tissue that behaves as a foreign body within the cornea. The aetiology is unclear, although several contributory factors have been proposed. This article outlines presentation, pathology and management options for corneal sequestrum, and summarises the role of registered veterinary nurses in the care of patients with ocular disease.
