A coloboma, or hole, may form in or near the optic disc due to a failed closure of embryonic tissue. The degree of these abnormalities varies between individual dogs, and even between the same dog's eyes. [7] CEA is inherited as an autosomal recessive trait that has a penetrance reaching 100 percent. [8] A mutation in the NHEJ1 gene is ...
“Cherry eye is a common eye condition in dogs where a gland in the third eyelid pops out and swells up, making it look like a red, swollen ‘cherry’ in the corner of the eye,” says Dr. Hood.
The least common type of glaucoma in dogs is primary open-angle glaucoma (POAG), although this is the most common type that affects humans. [1] In the Beagle, POAG is an inherited autosomal recessive trait. [2] Secondary glaucomas occur when other eye diseases alter the flow of aqueous humor either into or out of the eye.
Ocular melanosis (OM) is a disease of the eye which in dogs is almost found exclusively in the Cairn Terrier. The disease is caused by an increase of melanocytes in the iris, sclera, and surrounding structures. [63] Keratoconjunctivitis sicca (dry eye) is common in dogs. Symptoms include eye redness, a yellow or greenish discharge, ulceration ...
