The authors analysed the cases of 13 patients, operated upon for chronic glaucoma with marked visual-field defects. The visual field was examined with a Zeiss spherical perimeter. The field area was calculated in cm2 by planimetric method before the operation and then some months after it, and the obtained results were compared. Special attention was paid to vascular disturbances. In most patients with regular vascular system, post-operative examination had revealed an increase of the visual field. The best results were obtained in patients with medium-size defects: in these cases the increase in the visual field amounted to ca. 33%. The authors recommended proceeding to operative treatment in glaucoma patients without delay whenever there are defects in the visual field, even when they are very pronounced.
作者分析了13例因慢性青光眼伴明显视野缺损而接受手术的患者病例。使用蔡司球面视野计检查视野。术前及术后数月采用平面测量法计算视野面积（单位为平方厘米），并对所得结果进行比较。特别关注血管紊乱情况。在大多数血管系统正常的患者中，术后检查发现视野有所扩大。中等大小视野缺损的患者取得了最佳效果：在这些病例中，视野扩大约33%。作者建议，只要青光眼患者存在视野缺损，即使缺损非常明显，也应立即进行手术治疗。
