Figure 6. The comparison of full-field electroretinography between the proband (III:9) and the obligate carrier (II:1) in family ADRP-LG. Scotopic electroretinographs are nonrecordable, and other ERGs are severely reduced in III:9. Although the amplitudes of a-waves and b-waves of bright flash ERGs are slightly reduced, the other ERGs are within the normal range in the asymptomatic carrier II:1. The ERG protocol we used in this study complied with the standards published by the International Society for Clinical Electrophysiology of Vision (ISCEV). The light levels used to stimulate the eyes are available on the ISCEV Internet site.
