【Abstract】 AIM: To explore the exact parameters (frequency and intensity of stimulus) which can isolate cone system electroretinogram (ERG) bwave under light adaptation in SD rats and to provide some clues for further study. METHODS: With RETIscan system, lightadapted ERG from SD albino rats were obtained. Eight frequencies (0.1, 0.5, 5.0, 10.0, 15.0, 20.0, 25.0 and 30.0 Hz) and seven intensities (0.11, 0.35, 1.10, 3.50, 11.00, 35.00 and 110.00 cd・s・m-2) were used. The intensity of adapting field luminance was 37.00 cd・s・m-2 and the adaptation time was 10 min. RESULTS: In the condition of lowfrequencies（0.1, 0.5, 5.0 Hz）, there was rod system intrusion and steady wave could not be r
