Increasing the sensitivity of methods of examining the visual field may merely increase subjective errors already inherent in this test. The optic disc can be examined quite objectively and subtle changes are best assessed by photography. A method, evolved through trial and error, is outlined for obtaining high quality colour transparencies and Polaroid Land Prints of the optic disc for follow up. Routine disc photography should be an important part of a glaucoma record.
提高视野检查方法的敏感度可能只会增加该测试中原本就存在的主观误差。视盘可以进行非常客观的检查，细微变化最好通过摄影来评估。本文概述了一种通过反复试验得出的方法，用于获取高质量的视盘彩色透明片和宝丽来一次成像照片以便后续观察。常规的视盘摄影应该成为青光眼病例记录的重要组成部分。
