Collie eye anomaly (CEA) is a congenital, inherited, bilateral eye disease of dogs, which affects the retina, choroid, and sclera. It can be a mild disease or cause blindness. CEA is caused by a simple autosomal recessive gene defect. There is no treatment.

Collie eye anomaly (CEA), a genetic disease which causes improper development of the eye and possible blindness, is a common ailment in the breed. [8] More rarely, Rough Collies can be affected by progressive retinal atrophy (PRA), another genetic disease in which bilateral degeneration of the retina results in progressive vision loss ...
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 ...
“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 three most common serious conditions that can affect Heelers are Collie eye anomaly, primary lens luxation and persistent pupillary membranes. [5] As well as these eye conditions, dogs of this breed may suffer from Patella luxation. [6]
Symptoms include sudden permanent blindness, but may occur more slowly over several days, weeks or months, [3] dilated pupils.Pupillary light reflexes are usually reduced but present; the slow phase mediated by melanopsin in retinal ganglion cells is retained.
Dogs not registered can become eligible for registration by being awarded a certificate of working ability by a registered judge. Occasionally they will facilitate the testing of dogs used for breeding, for hip dysplasia and collie eye anomaly, to encourage the breeding of dogs without these genetic flaws.
