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① 60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

To investigate the diagnostic value of HRT-II for chronic primary angle-closure glaucoma（CPACG）. MethodsThirty 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. Results1. 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). ConclusionHRT-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.
