目的 探讨图形视网膜电图联合视网膜神经纤维厚度测定对于青光眼的诊断的临床意义.方法 选自2007年5月至2009年09月在我院经治的青光眼患者40例进行PERG,PVEP和OCT及视野检查,并对检查结果进行分析处理,分析各种方法对于青光眼的早期诊断所具有的特异性和敏感性.结果 PERG、PVEP在青光眼组与对照组的比较中差异具有统计学意义(P＜0.05).青光眼组PERG与PVEP振幅异常率比较差异具有统计学意义(P＜0.05).青光眼组PERG与OCT异常率指数比较差异具有统计学意义(P＜0.05);在早期青光眼的异常率的比较显示PERG较PVEP,OCT和视野明显(P＜0.05).结论 图形视网膜电图联合视网膜神经纤维厚度测定对于青光眼的诊断具有很大的临床意义,在很大程度上提高了青光眼早期诊断的准确率,值得在临床广泛使用和推广.%Objective To explore the clinical signifficance of pattern electroretino gram and retinal nerve layer thickness in the diagnosis of glaucoma .Methods Choose 40 cases of glaucoma treated in our hospital from May 2007 to October 2010 .They were inspected by PERG ,PVEP and OCT and vision .and do statistical analysis of the test results .Do analysis of the specificity and sensitivity of various methods in the early diagnosis of glaucoma. Results The comparisons of ergometry glaucoma PERG ,PVEP of the two groups had significatnt difference ( P＜0.05 ) .Glaucoma PERG PVEP amplitude of abnormal rate index with the statistical meaning of comparative significantly ( P＜0.05 ) .OCT of Glaucoma group with the statistical meaning of comparative significantly ( P＜0.05 ).Early in the abnormal rate of glaucoma PERG comparison shows for 80％ ,obviously better than the PVEP ,OCT and vision ( P＜0.05).Conclusion In the diagnosis of glaucoma Graphics retinal electricity figure joint retinal nerve fiber thickness measuring had great clinical significance ,and greatly in prove the diagnostic accuracy ,and were worth used widely and promoted.
