My cat is squinting one eye, what should I do?

Pets can squint for many reasons ranging from a corneal ulcer to glaucoma. If your cat or dog is suddenly squinting one or both eyes the best thing you can do is get him to a veterinarian. Several tests can be performed to determine the cause of the squinting including tear production testing, corneal staining to look for ulcers, and measurement of intraocular pressure to assess for glaucoma or ocular inflammation. Based on the results of these tests it can be determined what medications can be used to treat your pet’s underlying problem. Because vision is important to pets, any time there is a problem involving the eyes we recommend having your pet evaluated by a veterinarian immediately.
