摘要

PURPOSE: To determine the relationship of the photopic negative response (PhNR) of the photopic electroretinogram (ERG) with the degree of circulatory disturbances in eyes following central retinal artery occlusion (CRAO). METHODS: The circulatory disturbance was graded as mild (group 1) when the arm-to-retina transmission time was 30 s and severe (group 3) when concurrent choroidal circulatory damage was found. For statistical analysis, groups 1, 2 and 3 were scored as 1, 2 and 3, respectively. Photopic ERGs were elicited by either short-flash (SF) or long-flash (LF) stimuli. RESULTS: Both the SF and LF PhNR were significantly reduced in groups 2 and 3. The PhNR amplitude was negatively correlated with the severity of the ocular circulatory disturbances (p = 0.0498, rho = -0.507 for SF PhNR; p = 0.0050, rho = -0.750 for LF PhNR). CONCLUSION: The amplitude of the PhNR became more reduced as the severity of the circulatory disturbances increased in eyes with CRAO.
