目的：探讨用心理物理的方法检测糖尿病患者黄斑部功能在糖尿病视网膜病变（ｄｉａｂｅｔｉｃｒｅｔｉｎｏｐａｔｈｙ，ＤＲ）诊断中的意义。方法：对１５名正常人的３０只眼和４１例糖尿病患者的８２只眼（无视网膜病变２７只眼，单纯型５５只眼）黄斑部光敏感度进行检测并与图形视觉诱发电位（ｐａｔｅｒｎｖｉｓｕａｌｅｖｏｋｅｄｐｏｔｅｎｔｉａｌ，Ｐ－ＶＥＰ）检测结果进行对比。结果：糖尿病患者黄斑部光敏感度明显低于正常组（Ｐ＜０．０１）；在糖尿病组，黄斑部光敏感度异常检出率为６２．１９％，Ｐ－ＶＥＰ异常率为６９．５１％。结论：黄斑部光敏感度检测对糖尿病患者视网膜病变和早期视功能损害的检测有一定临床价值。
Objective: To explore the significance of detecting macular function in diabetic patients with diabetic retinopathy (DR) by using psychophysical methods. Methods: The macular light sensitivities of 30 eyes of 15 normal subjects and 82 eyes of 41 diabetic patients (27 eyes without retinopathy and 55 eyes of simple type) were detected and compared with those of the pattern visual evoked potentials (P -VEP) test results for comparison. Results: The photosensitivity of macular in diabetic patients was significantly lower than that in normal controls (P <0.01). In diabetic patients, the detection rate of abnormal photosensitivity in macular was 62.19% and the abnormal rate of P-VEP was 69.51%. Conclusion: The detection of macular light sensitivity has some clinical value in the detection of diabetic retinopathy and early visual impairment.
