The authors photographically measured the optic disks in 6 groups, namely, normal subjects with small cups and those with large cups, suspected glaucoma with small cups and those with large cups, primary open angle glaucoma (POAG) and low tension glaucoma (LTG). The effect of ocular optical magnification was corrected. The mean NRAs of POAG, LTG and suspected glaucoma with large cups were found less than those of the other 3 groups. In the normal subjects, an evident positive correlation existed between the cup area and the disk area, and the NRA was weakly correlated with the disk area. The diffuse and localized retinal nerve fiber layer defects were negatively correlated with the NRA significantly.
作者对6组对象的视盘进行了摄影测量，这6组分别为小视杯正常受试者、大视杯正常受试者、小视杯疑似青光眼患者、大视杯疑似青光眼患者、原发性开角型青光眼（POAG）和低眼压性青光眼（LTG）。校正了眼屈光放大的影响。发现POAG、LTG和大视杯疑似青光眼患者的平均负相对调节（NRA）低于其他3组。在正常受试者中，视杯面积与视盘面积之间存在明显的正相关，且NRA与视盘面积呈弱相关。弥漫性和局限性视网膜神经纤维层缺损与NRA显著负相关。
