摘要 目的通过检测视网膜神经纤维层厚度(RNFL)及视盘结构参数,结合视野改变,探讨光学相关断层成像术(OCT)在青光眼早期诊断中的价值。方法采用OCT对正常人10眼、疑似青光眼患者34眼,慢性闭角型青光眼(CACG)早中期患者36眼进行视盘扫描及以视乳头中心为圆心、直径为3.4 mm的环形扫描,观察各组人群的OCT图像特征。分别比较各组受检者的各象限RNFL厚度、视乳头水平、垂直杯盘比及杯/盘面积比,平均RNFL厚度与视野指数进行直线回归和相关分析。结果OCT检测正常人、疑似青光眼和CACG早中期三组间各象限RNFL厚度、各视盘参数均有显著性差异(P<0.05)。平均RNFL厚度与视野平均缺损值(MD)呈强的且正的直线关系。结论OCT能够早期反映RNFL厚度及视盘的改变,与视野检查有较好的相关性,可以作为青光眼早期诊断的方法。
