![]() Persistent hyperplastic primary vitreous.Retinal dysplasia (geographic or detached).Cataracts (intermediate or diffuse, with some exceptions).The following defects will result in “No Breeding” advice in any breed of dog: Intermediate or diffuse cataracts would be an example of a “No Breeding” condition while punctate cataracts fall under “Breeder Option.” (This specific situation will be discussed in greater detail later.) Something that may be inherited but doesn’t cause significant reduction in the dog’s vision may be classed as “Breeder Option,” meaning the breeder is put on notice that this condition is or may be inherited but it is her call as to whether to breed the dog or not. If a dog has a condition that meets these criteria, ACVO vets will advise the owner not to breed it. Registration of the findings of cooperating ACVO vets and the issuance of certificates in North America is the domain of the Canine Eye Research Foundation (CERF) or the Orthopedic Foundation for Animals (OFA).ĪCVO’s breeding advice is based on either or both of two criteria: Severity of the condition and strong evidence that it is inherited. ![]() Though we commonly refer to getting “eye certification,” ACVO states that their diplomates (vets who have passed the board exam) do not “certify” or “register” dogs, but give breeding advice. The ACVO maintains a list of diseases known or suspected to be inherited in dogs. ACVO has a genetics committee which keeps screening criteria up-to-date with current knowledge of canine inherited eye disease. A vet who is not board certified should not be relied upon for screening exams or specialized treatment of eye disease. ACVO certifies veterinary ophthalmologists in North America. The American College of Veterinary Ophthalmologists (ACVO) sets the criteria for examination. How do the vets decide what passes and what doesn’t? How come if it’s OK in another breed it isn’t in Aussies or vice versa? We know something about what diseases we need to watch out for. We learn that eyes need to be checked not once, but many times throughout a dog’s life. May 2013Įvery serious breeder of Australian Shepherds soon learns that inherited eye disease is a major concern. Plummer coordinates ophthalmic surgery laboratories at the NAVC Conference and has participated in the NAVC equine ophthalmology in-depth seminars and laboratories.Understanding the ACVO eye sceening programįirst published in the Australian Shepherd Journal, Sep-Oct 2002, Rev. Her research interests include corneal disease and glaucoma. She completed her internship at Michigan State University. PLUMMER, DVM, DACVO, is on faculty at University of Florida, where she completed her DVM and a residency in comparative ophthalmology.

Stimulate each eye separately with a bright light: both pupils should constrict in response to bright light one pupil failing to constrict fully indicates the affected eye. In ambient lighting, use a dim light source held at least arm’s distance from the patient to visualize the tapetal reflection, which will delineate pupil size.ĭarken the room and using the light source to visualize the tapetal reflection, evaluate the degree of dilation in each pupil: both pupils should dilate in darkened conditions one pupil failing to dilate indicates the affected eye.
