摘　　要：目的探讨眼底断层扫描(Heidelberg Retina Tomograph HRT)检测开角型青光眼患者与正常对照个体视盘参数与其相应视野改变的一致性。方法对100例正常个体、32例开角型青光眼进行HRT及视野检查,将结果进行对照分析。结果100例正常对照组视野检查、HRT检查均正常,开角型青光眼患者视野、HRT则出现不同程度改变。对于开角型青光眼在视野缺损一侧HRT检查显示视盘参数改变较视野正常一侧杯盘面积比、缘面积、纤维层厚度等特异性指标改变更加明显。这一结果表明视野出现不对称性改变,盘缘组织亦出现不对称,HRT参数反映出视盘的改变与视野损害的部位一致。结论应用HRT及视野检查可以早期发现开角型青光眼,且HRT较视野具有更高的重复性、敏感性、特异性,二者同时进行检查,有助于在开角型青光眼尚未出现症状时早期发现和早期治疗。Objective To investigate whether the glaucomatous optic changes detected by Heidelberg Retina Tomography （HRT） is consistnet to the distribution of visual field defects and the value of Heidelberg Retina Tomograph parameter in primary open angle glaucoma. Methods 32 patients with open angle glaucoma an 100 normal subjects were detected by Humphrey Field Analyzer （HFA） and by HRT. Results The parameters of HRT of 100 normal subjects are normal, so do their results of HFA. In the 32 open angle glau- coma, comparing with the half disc corresponding to the intact hemifield, the half disc corresponding to the detective hemifield has significantly higher values of cup/disc area ratio, rim area and thickness of retina nerve fiber layer. Conclusions The optic disc changes detected by HRT are consistent to the distribution of the visual field defects.
