Abstract

A battery of vision tests was used to quantify visual defect in a group of 50 patients with chronic simple glaucoma. The vision tests were near and distance visual acuity, visual fields, and contrast sensitivity to static and temporally modulated sinusoidal grating patterns. Of these, static contrast sensitivity function appears to be the most sensitive method of measuring visual defect in glaucoma patients. The visual disability experienced by the glaucoma patients was quantified by means of a questionnaire, and the relationship between perceived visual disability and visual defect was examined. It was found that results from a group of tests, near visual acuity, visual field, and contrast sensitivity measures, are the best predictors of the difficulty experienced by patients in performing visually dependent daily activities.

摘要

采用一系列视力测试来量化50例慢性单纯性青光眼患者的视觉缺陷。这些视力测试包括近视力和远视力、视野以及对静态和时间调制正弦光栅图案的对比敏感度。其中,静态对比敏感度函数似乎是测量青光眼患者视觉缺陷最敏感的方法。通过问卷调查对青光眼患者的视觉残疾进行量化,并研究了感知到的视觉残疾与视觉缺陷之间的关系。结果发现,一组测试的结果,即近视力、视野和对比敏感度测量结果,是预测患者在进行依赖视觉的日常活动时所遇到困难的最佳指标。
