Corneal Sequestrum

Corneal sequestrum is a disease affecting the cornea (the clear curved transparent part of the front the eye). The sequestrum is usually an area of degenerated or non-living corneal tissue. This develops after an area of chronic corneal irritation or non-healing ulceration.

Signs of corneal sequestrum

Corneal sequestrum is most often seen in cats, particularly flat-faced breeds, and occasionally in dogs. Signs include squinting, excessive tearing, redness and a brown or black spot on the surface of the eye.

Why prompt care matters

Eye problems can worsen quickly, so squinting or discoloration should be checked promptly. Treatment may include medication and, in many cases, surgery to remove the affected tissue.
