So, whats the context for CERF? Whats the end result with CERF data?
For CERF, it’s this: CERF records are not required on all registered dogs. The CERF forms are used by the veterinary ophthalmologist when the owner chooses to request and pay for a CERF exam. CERF counts one report form per dog per year, and dogs must be re-CERFed annually. Clearly, a dog that CERFs normal is likely to be re-CERFed in following years. These dogs will be part of the numbers year after year. In contrast, the dog that fails a CERF exam probably will not be re-examined for CERF registration–it already failed. That dog’s standing is included in the count for one year only, but not year after year. Not only that–but a dog that has already been diagnosed with an eye problem likely won’t be given a CERF exam at all. (Note that the general eye exam form used by ACVO’s does not go to CERF, so many diagnoses are not registered. Only the specific CERF forms go to CERF.) CERF numbers significantly underestimate the frequency of PRA and other inherited eye diseases in any breed.
