Loss of sensitivity in chronic open-angle glaucoma is generalized, but heterogeneous. Particular parts of the visual field deteriorate proportionally, which also applies to the spatial behaviour. The proportionality factor and the slope of decay are most pronounced at the nasal and superior border of the field. In single cases, the topography of the field is variable, but it follows the retinal nerve fiber lines. For follow-up, topography seems to be unimportant. A number of standard threshold programs are adequate for this task. For follow-up the same type of instrument and the same program should always be used. The optimal value for analysis in perimetric follow-up is so far unknown. Although progression is often not linear, linear regression seems to be the most suitable statistical procedure. Some new methods of visualization help to process the information like the double representation, GATT, time diagram or the gray-scale bar.
慢性开角型青光眼的敏感性丧失是全身性的,但具有异质性。视野的特定部分会成比例地恶化,空间行为也是如此。比例因子和衰退斜率在视野的鼻侧和上边界最为明显。在个别情况下,视野的地形图是可变的,但它遵循视网膜神经纤维线。对于随访而言,地形图似乎并不重要。许多标准阈值程序足以完成此任务。随访时应始终使用同一类型的仪器和相同的程序。目前尚不清楚视野计随访分析的最佳值。尽管进展通常不是线性的,但线性回归似乎是最合适的统计方法。一些新的可视化方法有助于处理信息,如双重表示、GATT、时间图或灰度条。
