BVA/KC/ISDS Eye Scheme
The BVA/KC/International Sheep Dog Society (ISDS) Eye Scheme offers breeders the possibility of eye testing to screen for inherited eye disease in certain breeds. By screening breeding stock for these diseases, breeders can use the information to eliminate or reduce the frequency of eye disease being passed on to puppies. At the centre of the scheme are two schedules: Schedule A and Schedule B.
Schedule A contains a list of breeds and eye conditions that are known to be inherited in those breeds. Under the Eye scheme one of a specialist group of canine ophthalmologists (the Eye Panel) examines a dog to look for clinical signs of inherited disease known to affect the breed in question. If no clinical signs are noted for these diseases, then the dog is declared ‘unaffected’; if signs consistent with one or more Schedule A conditions, then the dog will be declared ‘affected’ for the relevant disease. These results are passed to the KC for inclusion in the tested dog’s registration database. Only the results of Schedule A examinations are available to the Health Test Result Finder.

In general, it is recommended that eyes are examined annually (except for glaucoma predisposition which is only done once by gonioscopy), with the advice given to breeders to only breed from dogs that are found to be unaffected (or clear) of all known conditions in the breed.
