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。方法分别用HRT-Ⅱ和自动视野计（ Humphrey ）对40例（80眼） CPACG患者的视盘和视野进行检测，并对视盘参数与视野平均缺损作相关性分析，统计分析HRT-Ⅱ检测的敏感性。结果 HRT-Ⅱ检测异常74眼，Humphrey检测视野异常72眼，视野异常和HRT-Ⅱ异常符合率为97.30％；Humphrey检测视野正常8眼中HRT-Ⅱ检测异常2眼、正常6眼，HRT-Ⅱ检测正常6眼中Humphrey 检测6眼视野均正常。盘沿面积（RA）、盘沿体积（RV）、视杯形态测量（CSM）与平均视野缺损（MD）呈正相关，杯盘面积比（CDAR）与MD呈负相关。结论 HRT-Ⅱ检查敏感性良好，与视野检查有良好的相关性，可以用于CPACG患者视神经损害的监测及早期诊断。%Objective To explore the diagnostic significance of the Heidelberg retina tomograph ( HRT-Ⅱ) in primary chronic angle-closure glaucoma(CPACG).Methods HRT-Ⅱand automatic perimeter(Humphrey detec-tion) were used in 40 cases(80 eyes) of CPACG for testing optic disk and visual field , and the correlation between the optic disk parameters and average defect of visual field were analyzed , the statistical analysis of HRT-Ⅱdetection sensitivity was performed.Results Seventy-four eyes were abnormal by HRT-Ⅱdetection, and 72 eyes were abnor-mal by Humphrey detection , the coincidence rate between Humphrey detection and HRT-Ⅱdetection was 97.30%. In 8 eyes which were normal visual field in Humphrey detection , there were 2 eyes abnormal and 6 eyes were normal in HRT-Ⅱdetection.In 6 eyes which were normal in HRT-Ⅱdetection, there were 6 eyes were normal visual field in Hunphrey detection .The average visual field detects ( MD) showed a statistically significant positive with rim area (RA), rim volume(RV), optic cup shape measurement (CSM) and a negative correlation with cup dish area ratio ( CDAR) .Conclusion HRT-Ⅱ detection has a high sensitivity and a better correlation with Humphrey detection , and can be used for monitoring and early diagnosis of optic nerve damage in patients with CPACG .
