All of us mammals were born with two eyes, and when something goes wrong with one of them, help should be sought. We see a variety of eye abnormalities in companion animal medicine. Here are some examples…
|The most common eye trouble that we see is the corneal ulcer. When something injures/scratches the cornea, the eye becomes irritated and the ulcer can become infected. An ulcer is diagnosed with a special stain, and treatment involves appropriate antibiotic therapy and lubrication. Ulcers should be treated aggressively as they can only get so deep before the eye is irreversibly injured.
|There are four main muscles that move the eye and hold it in position. An injury to one of these muscles manifests as overcompensation on the opposite side. This dog suffered an injury to the medial (nose-side as opposed to ear-side) muscle.
|When animals get into “wrestling matches” with other animals, they can suffer injury to the tissue around their eyes, impairing their vision.
Or they can suffer such trauma that their eye comes out of the socket. This kitten came to us more than a week after the injury.
|Eosinophilic plaques are cellular accumulations on top of the cornea and are quite uncomfortable for cats.
|When cancer shows up as a tumor behind the eye, the pressure within the eye increases and the tissue around the eye can become inflamed.
|Iris cysts rarely need to be treated, though they can burst and coat the back of the cornea with pigment.
|Synechia is an attachment of the iris to either the cornea or the lens. In this case, the cat suffered an full-thickness injury to the cornea, and in the healing process, the iris stuck to the back side of the cornea.
|Some eye abnormalities have been present from birth.Persistent pupillary membranes aren’t normal, but there’s no reason to pursue treatment for them.
Dermoids are the presence of haired skin on the eye. These should be surgically removed… with great care!
This is by no means an exhaustive list of the ophtho abnormalities that we see. We also see glaucoma and uveitis on a regular basis, though photographs don’t illustrate those conditions too terribly well. Hopefully, though, this enough of a sampling for you to see that anything unusual with an eye ought to be examined by a veterinarian.
Some of the conditions above need immediate treatment while others are unusual, but not impacting the animal’s quality of life.
For those that need immediate treatment, ignoring the problem could cost the patient an eye, and if treatment is needed, necessary treatment ought not be delayed.
