What is Entropion?
Entropion is an inward rolling of the edges of the eyelid so that the eyelashes (called cilia) rub against the eye surface. In cats, it usually affects the lower eyelids of one or both eyes. This condition can cause discomfort and irritation to the cornea and possibly, vision impairment.
How does my cat get Entropion?
Fortunately, entropion is not common in cats, but generally, is congenital, especially in purebred cats who have short, round faces like Burmese, Persian and Himalayans. Entropion can also develop in adult cats diagnosed with feline herpesvirus or chronic eye spasm. It can also occur with other eye problems such as corneal ulcers, chronic conjunctivitis and scarring.
How do I know if my cat has Entropion?
Examine your cat’s eyes closely and look for signs of tearing, wetness on hairs next to the eyelids, squinting, paw rubbing of the eyes, thick mucus discharge from the eyes, redness or swelling along the inner lining of the eyelids, changes in or around the cornea, and rolling of the eyelid. The diagnosis will be confirmed by a veterinarian performing an ocular examination. A fluorescein dye will be applied to detect any corneal ulcers created by constant rubbing of the eyelashes against the cornea. The cat may also be tested for the presence of herpesvirus.
What can I do about Entropion?
Surgery is often necessary for cats born with entropion and for some cats who develop it as a secondary condition. It is strongly advised to have the surgery performed by a veterinary ophthalmologist or a veterinarian experienced in this procedure. Non-surgical options include antibiotic ointments.
Is there anything I can do to prevent my cat from getting Entropion?
Report any signs of eye problems to your veterinarian without delay before the condition worsens. If there has been eye trauma, have your cat checked by a veterinarian immediately.
Are there certain breeds that get more Entropion often?
Persians, Himalayans and cats with round-faced, pushed-in noses (Brachcephalic) are more prone to having this eye condition. It can also affect some Bengals and Burmese breeds.
