With the advent of automated static perimetry has come the common practice of measuring only the central 30 degrees of vision in the diagnosis and management of glaucoma. While most glaucomatous field defects appear first in this portion of the visual field, the question remains as to how much useful information is being missed by ignoring the peripheral field, i.e., outside the central 30 degrees. Studies with both static and kinetic automated perimetry have revealed the same peripheral glaucomatous field defects previously recognized with manual perimetry, including generalized contraction, nasal steps, temporal sector defects, and hemianopic offsets. Of these, however, only measurement of the nasal periphery may add sufficient information to that obtained with static testing in the central 30 degrees to justify the added examination time; however, there are special situations in which peripheral field testing in other or all quadrants may be useful. Further study is required to establish optimum techniques for automated measurement of the peripheral visual field and to determine the significance of the results in the management of glaucoma.
随着自动静态视野计的出现，在青光眼的诊断和管理中仅测量中央30度视野已成为常见做法。虽然大多数青光眼性视野缺损首先出现在视野的这一部分，但忽略周边视野（即中央30度以外）会遗漏多少有用信息的问题仍然存在。静态和动态自动视野计研究均揭示了先前通过手动视野计识别出的相同周边青光眼性视野缺损，包括普遍收缩、鼻侧阶梯、颞侧扇形缺损和偏盲性偏移。然而，其中只有鼻侧周边的测量可能会为在中央30度进行的静态测试所获得的信息增添足够内容，从而证明增加的检查时间是合理的；不过，在某些特殊情况下，对其他象限或所有象限进行周边视野测试可能会有用。需要进一步研究以确立自动测量周边视野的最佳技术，并确定结果在青光眼管理中的意义。
