[2][3][4] This disease is painful to the cat, although it develops slowly over a longer period of time.
[1] The corneal sequestrum is painful, and the cat may show this by squinting or closing the eye (blepharospasm).
Lubricating eye drops are usually given in the first instance of feline corneal sequestra, yet if the eye continues to irritate the cat or becomes worse, surgical removal is usually required.
Once the removal of the corneal sequestrum is complete, cats will usually remain on lubricating eye drops for the rest of their lives.
Any breed of cat may develop a corneal sequestrum, although Persians, Exotic Shorthairs and Himalayans may be more susceptible to developing sequestra than other breeds of cat.
