Feline Corneal Sequestrum FAQs
If you have questions about this resource, contact the College of Veterinary Medicine.
Summary
The feline corneal sequestrum is a condition primarily affecting cats in which a pigmented area of dead tissue develops on the cornea. It is caused by chronic eye irritation such as trauma, non‑healing ulcers, eyelid abnormalities, dry eye, reduced corneal sensation, or feline herpesvirus, with Persian and Himalayan cats being predisposed. The lesion progresses from light discoloration to a dark plaque and may cause inflammation or infection. Treatment options include medical management to allow natural sloughing or surgical removal with corneal grafting, with recurrence possible in some cats.
