OBJECTIVE: To evaluate the function of the outer retina in Papillons with and without @entity2000 . ANIMALS: 45 Papillons, median age 1.7 (range, 0.8 to 5.1) years. PROCEDURE: Complete physical and ophthalmic examinations were done prior to performing electroretinography under general anesthesia. Full-field electroretinograms (ERG) were recorded, using a special-purpose computer system. Eleven specific ERG responses were recorded, graphed, and evaluated, using age-matched Papillons. RESULTS: Severely decreased retinal function was detected in 8 Papillons. The youngest affected @entity235 was 1.2 years old. In affected @entity235 , amplitudes of responses mainly originating from the rod system were severely decreased, compared with those originating from the cone system. CONCLUSIONS: Papillons represent another breed of @entity235 affected by a @entity2746 that can be detected at an early age by using ERG. A reliable age for diagnosis using ERG is considered to be 1.5 years. CLINICAL RELEVANCE: Through and precise ERG procedures and protocols are needed to reliably obtain an early diagnosis of progressive @entity2479 .
