Understanding the Canine Eye Registration Foundation (CERF)

The Canine Eye Registration Foundation (CERF) is a vital organisation dedicated to reducing hereditary eye diseases in purebred dogs. Through rigorous eye testing by veterinary ophthalmologists, CERF helps dog owners and breeders recognise potential hereditary eye conditions in their dogs, supporting informed breeding decisions to promote healthier future generations.

CERF maintains a comprehensive registry of dogs certified free of hereditary eye diseases, enabling breeders to choose mates with good eye health and thus lessen the prevalence of these conditions over time. This contributes significantly to the overall improvement of canine health within specific breeds and the wider dog community.

What CERF offers to dog owners and breeders

Though based in the USA, CERF collaborates internationally, including within the UK, to collate eye test data and support breeders worldwide. Its main services include:

• Maintaining a publicly accessible registry of purebred dogs that have passed stringent eye exams.
• Providing membership opportunities, with newsletters detailing advances in canine ophthalmology testing and treatments.
• Publishing breed-specific data on hereditary eye conditions, helping to track progress and raise awareness.
• Offering resources for veterinary professionals, breeders, and owners seeking information about eye health in dogs.
• Certifying canine eye testing schemes globally, which helps breeders assess the eye health status of their breeds.

The goals and mission of CERF

CERF was founded through collaboration between concerned dog breeders, owners, and board-certified veterinary ophthalmologists to combat the impact of hereditary eye diseases within purebred dogs. Its ultimate aim is the elimination of these conditions through widespread screening, data collection, research, and education.

The CERF registry holds valuable data on all dogs tested, including those diagnosed with hereditary eye problems. This comprehensive database supports research efforts, assists breeders in making wise decisions, and fosters healthier bloodlines, crucial for the long-term wellbeing of various breeds.

How eye testing is conducted

Dogs undergo examination by a CERF-affiliated veterinary ophthalmologist, who assesses for any hereditary eye abnormalities or diseases. Test results are recorded and submitted to CERF, and if clear, the dog receives a certification valid for one year.

While the results and subsequent breeding recommendations are not legally binding, responsible breeders typically follow the guidelines to avoid passing on inheritable eye diseases. Retesting annually is recommended to maintain current health status records.

Integration with DNA testing

DNA testing complements CERF's eye exams by helping identify genetic predispositions to eye conditions within breeds and individuals. Though specific dog identities are kept confidential, aggregated data contributes to a broader understanding of hereditary eye health trends and supports progress towards eradicating these diseases.

Why CERF matters for responsible dog ownership

By encouraging annual eye checks and transparent reporting, CERF empowers breeders and buyers alike to prioritise canine health and reduce suffering caused by hereditary eye illnesses. This fosters ethical breeding practices and supports the welfare of dogs across generations.
