Corneal dystrophy is an inherited progressive condition which affects both eyes, often in the same way. The cornea, the clear outer layer of the front of the eye, is most affected. The disease is not associated with other diseases, and only rarely occurs in cats.
There are three types of corneal dystrophy, categorized by location: epithelial corneal dystrophy, where cell formation is affected; stromal corneal dystrophy, where the cornea will become cloudy; and endothelial corneal dystrophy, where the cells of the lining of the cornea are affected.
Epithelial corneal dystrophy:
Stromal corneal dystrophy:
Endothelial corneal dystrophy:
Cats breeds that are predisposed:
Your veterinarian will perform a thorough physical exam on your cat, including an ophthalmic exam. Your veterinarian will order a blood chemical profile, a complete blood count, an electrolyte panel and a urinalysis. will need to provide a thorough history of your cat's health leading up to the onset of symptoms.
Slit lamp microscopy will aid significantly in differentiating the type of corneal dystrophy present, and a fluorescein stain, a non-invasive dye that shows details of the eye under blue light, will be used to examine the eye for abrasions, and to define the shape of the cornea so that your veterinarian can diagnose the corneal dystrophy. Fluorescein dye enables visualization of any corneal ulcers that may be present; these types of ulcers occur with endothelial and epithelial corneal dystrophy. Fluorescein dye is inconsistent in its ability to aid in diagnosis of endothelial corneal dystrophy, and is not of much use in the diagnosis of stromal corneal dystrophy, but it can be helpful in the diagnosis of epithelial corneal dystrophy. A tonometer will be used to measure the interior pressure in your cat’s eyes so as to rule out glaucoma as a possible cause of corneal swelling.
