Corneal Sequestrum in Cats: Welfare and Treatment

Corneal sequestrum is a painful eye condition unique to cats. This guide covers welfare impacts, treatment, and post-operative care.

Key Facts

Corneal sequestrum involves necrosis and darkening of corneal tissue
It is unique to domestic cats and certain wild felids
Brachycephalic breeds (Persians, Himalayans) are most commonly affected
Chronic corneal irritation, including herpesvirus, is a common predisposing factor
Signs include dark corneal plaque, ocular discharge, pawing at the eye, and pain
Surgical removal (keratectomy) is the treatment of choice

Welfare Considerations and Management

Welfare-centred management requires prompt surgical intervention as sequestra cause progressive pain and potential corneal perforation. Superficial keratectomy removes the sequestrum and diseased tissue. Post-operative contact lenses protect the cornea during healing. Pain management before and after surgery is essential. Herpesvirus management (antiviral eye drops, lysine supplementation) reduces recurrence risk in susceptible cats.

What You Can Do

Seek prompt veterinary assessment for any dark spot on a cat's eye
Pain management before surgery improves welfare in the pre-operative period
Follow post-operative instructions carefully to support corneal healing
Manage any underlying herpesvirus to reduce recurrence risk
