HRT-II在原发性慢性闭角型青光眼诊断中的应用

目的探讨海德堡视网膜断层扫描仪（HRT-II）在原发性慢性闭角型青光眼（CPACG）诊断中的意义。方法对30例（60眼）CPACG患者进行HRT-II检测及视野检查，统计分析HRT-II检测敏感性、病变分区特点及视盘参数与视野平均缺损的相关性。结果①60眼中视野异常53眼，HRT-II检测异常54眼；视野异常和HRT-II异常对应为98．15％；单眼视野组8例中有对侧2眼视野检测正常而HRT-II检测异常，对侧5眼视野检测正常而HRT-II检测也正常，对侧1眼HRT-II检测正常而视野检测异常。颞下象限盘沿面积异常率最高；②盘沿面积、杯，盘面积比、盘沿容积、视杯形态测量与视野平均缺损呈直线相关。结论HRT-II检查敏感性良好，与视野检查有良好的对应关系，可以用于CPACG患者视神经损害的监测及早期诊断。

Application of HRT-II in the diagnosis of chronic primary angle-closure glaucoma

Objective To investigate the diagnostic value of HRT-II for chronic primary angle-closure glaucoma(CPACG).Methods Thirty cases(60 eyes) of CPACG were detected by HRT-II and auto visual field examination.The sensitivity,characteristics of different disk section,and correlation between optic disc parameters and mean defect of the visual field were analyzed.Results 1.Fifty-three eyes were abnormal by visual field detection and fifty-four eyes abnormal by HRT-II.The corresponding ratio between visual field detection and HRT-II was 98.15%.In the group of single eye abnormal in the visual field,there were 2 eyes which were normal in the visual field but abnormal in HRT-II and 5 eyes were normal in both the visual field and HRT-II;1 eye was abnormal in the visual field but normal in HRT-II.The Rim area of the abnormal ratio in the temporal inferior section was the highest in HRT-II.2.Mean defection showed a statistically significant correlation with rim area,rim volume,cup/disc(C/D) area and cup shape(P<0.05).Conclusion HRT-II is sensitive and is related to the visual field result.HRT-II can probably be used for follow-up and early diagnosis of CPACG.
