目的：比较正常眼压性青光眼不同阶段视野丧失的视盘形态差异。设计：眼间成对比较。设置：一家教学医院的青光眼门诊。患者：13例正常眼压性青光眼患者，视野指数平均缺损中不对称视野丧失至少2.5 dB。干预措施：根据视盘径向截面值绘制的视盘轮廓下的面积，以30度为间隔测量，并表示为矩形面积的百分比，通过计算机图像分析系统从立体照片中获得。采用自动视野计（OCTOPUS），使用G1程序进行视野检查。主要观察指标：视盘下面积的眼间差异与视野指数的眼间差异之间的相关性分析。在上级至颞侧断面中，平均缺损的眼间差异与视盘轮廓下面积的眼间差异之间的相关系数为-.71至-.61（.007
Objective: To compare the differences in optic disc configuration with different stages of visual field loss in normal-tension glaucoma.Design: Interocular pairwise comparisons.Setting: Glaucoma clinic of a teaching hospital.Patients: Thirteen patients with normal-tension glaucoma and asymmetric visual field loss of at least 2.5 dB in the mean defect of the visual field indexes.Interventions: Areas under the optic disc profiles mapped from values for radial sections of the optic disc measured at intervals of 30-degrees and expressed as percentages of the area of a rectangle were obtained from stereophotographs with a computerized image analysis system. Visual fields were tested with automated perimetry (OCTOPUS), using program G1.Main Outcome Measure: Correlation analyses between the interocular differences in the areas under the optic disc profile and the interocular differences in the visual field indexes.Results: The correlation coefficients between the interocular differences in mean defect and those of the area under the optic disc profile in the superior to temporal sections ranged from -.71 to -.61 (.007
