The Companion Animal Eye Registry

Previously known as the Canine Eye Registration Foundation (CERF), the Companion Animal Eye Registry (CAER) information is found on the OFA public data base.

The purpose of the OFA EYE Certification registry is to provide breeders with the information regarding canine eye diseases so that they may make informed breeding decisions in an effort to produce healthier dogs.

These ocular exams are performed by board certified veterinary ophthalmologist.

Drops are administered to the dog’s eye to dilate the pupil.

Ocular exams can be done as early as 8 weeks of age since the eyes are essentially fully formed by this time. Recommendation by ophthalmologists are annual certification or at very minimum re-testing before being bred.
