Figure 2

The mean and typical traces in the right (A) and left (B) eyes of the patient are shown, and electroretinograms from an age-matched control subject with results within 2 SDs of the normal mean values representative of normal traces in this age group are shown for comparison (C). In the patient, photopic cone and 30-Hz Flicker responses were reduced and significantly delayed, the scotopic rod-specific response was delayed and reduced, and the maximal response was notably higher and more prolonged compared with the normative control.
