Feline corneal sequestrum
Corneal sequestration is a condition seen in cats and commonly in the Persian, Himalayan, Colourpoint, Abyssinian and Burmese breeds.
Aetiology:
Any cause of corneal irritation ranging from trauma, entropion, trichiasis, corneal exposure and viral infections e.g. cat flu (Feline Herpesvirus) can result in sequestra formation. In purebred cats such as Persians, the corneal exposure from a prominent eye is considered the most likely cause.
Surgery
There are three surgical options for treating corneal sequestra. All three should be performed by a Registered Veterinary Eye Specialist. An operating microscope is essential as the corneal thickness is less than 1 mm and can be easily perforated.
Prognosis
Conjunctival pedicle grafts and clear corneal-conjunctival transpositions prevent the recurrence of almost all sequestra. Without a graft, about 50% of sequestra will recur.
