摘要
越来越多的研究表明,早期青光眼患者在视力下降、视野缺损之前,就已有中心视功能受损。近年来,通过对早期青光眼的色彩分辨力,视觉对比敏感度、视诱发电位以及黄斑光阈值的检测和研究,均证实青光眼早期在中心视力下降和视野改变前即存在黄斑功能的损害。为了进一步探讨早期青光眼黄斑光阈值改变的特征,了解正常人黄斑光敏感性的特点,我们对正常人不同年龄组的黄斑光阈值进行了检测。
Use automatic perimetry of Humphery—630 testing macular light threshold within cen-tral area of 4(?).99 eyes of 51 normal subjects were studied.The results showed that macularlight sensitivity depressed with age.There is a negative correlation between the sensitivityand age (r=-0.888,p<0.01).No significant difference was found in different quadrants.Mean thresholds of superior and inferior,nasal and temperal to the macular area were nearlysame.We identified that there was no relation between macular light threshold and C/D ra-tio.
