The detail information of Collie eye anomaly
Basic Information

Disease Description: A condition of collie dogs where the narrow shape of the head causes the eyes to be malformed.

Inherit Mode: Inheritance is autosomal recessivewith variable expression and pleomorphism (meaning that there is a wide range in clinical expression of the defect).

Disease Symptom: Many dogs will have apparently normal vision unless retinal detachment with or without haemorrhage occurs, causing blindness in the affected eye. Retinal detachments are often one-sided and generally occur before 2 years of age.

Disease Cause: -

Disease Diagnose: Your veterinarian will be able to see the abnormalities in the back of the eye with an ophthalmoscope.

Treat Method: There is no treatment.

Breeder Advice: Minor lesions may not be detectable by ophthalmoscope after 3 months of age, so collies intended for breeding programmes should be examined early at 5-6 weeks of age. Even dogs with minor lesions (mild choroidal hypoplasia) should not be bred because their offspring may be affected with more serious forms of the disorder. Because of the potential for serious eye disease with this trait, neither affected dogs, their parents, or their offspring should be used for breeding. Siblings of affected dogs should not be used either, unless eye exams before 3 months of age demonstrate that they are unaffected.
