Full field electroretinograms (ERG), performed according to ISCEV standards. a ERG of Patient 1 performed under general anesthesia shows moderate to severely depressed responses from both cone and rod systems that are greater than could be attributed to anesthesia, myopic refractive error, partial retinal detachment, or mild supraduction. b Full field ERG of Patient 2 shows decreased amplitudes and delayed implicit times of the cone more than the rod system of both eyes. This ERG is consistent with cone-rod dystrophy
