148 normal eyes and 123 eyes of diabetic retinopathy patients were examined the red, green, blue primary color and black/white P-VEPs, with the conclusion that the latencies of P100 were significantly delayed in the diabetic group, particularly that of the blue color, which was also in positive correlation with the level of blood sugar and the duration of diabetes. The consistency of blue P-VEP with fluorescein angiographic examination in diabetic retinopathy was good, and the abnormality ratio of the former (73.0%) was higher than that of the latter (60.2%). The results indicated that S-wave cones were damaged more readily than were L-wave cones, and the blue P-VEP was sensitive in monitoring the injury to visual function in diabetes.
对148只正常眼睛和123只糖尿病视网膜病变患者的眼睛进行了红、绿、蓝三原色及黑/白图形视觉诱发电位（P-VEP）检查，结果显示糖尿病组P100潜伏期显著延迟，尤其是蓝色图形的P100潜伏期，且其与血糖水平及糖尿病病程呈正相关。糖尿病视网膜病变患者蓝色P-VEP与荧光素血管造影检查结果的一致性良好，前者的异常率（73.0%）高于后者（60.2%）。结果表明，S波视锥细胞比L波视锥细胞更容易受损，蓝色P-VEP对监测糖尿病患者视功能损伤较为敏感。
