Morphological and electrophysiological changes of retina after different light damage in three patients: Three case reports

Figure 2 Electrophysiological examinations of retina. A: Patent pattern visual monitoring (PVEP) examination revealed that the amplitude of P100 of PVEP was reduced in the left eye (a1, a2 and a3 correspond to stimulation frequencies of 0.5 cpd, 1 cpd and 2 cpd, respectively); B: Multi-fucus electroretinograms examination showed that the amplitude density of macular center was decreased in the left eye.
