The extent of cupping was measured from optic disc photographs of 300 patients with ocular hypertension and suspected or established chronic simple glaucoma, and their visual fields were recorded. The incidence of field defects increased as the vertical cup:disc ratio increased, a value of 0-70 for this ratio being a particularly useful guide to the presence or absence of field loss. There was a significant correlation between the extent of cupping and the size of the visual field. The vertical cup:disc ratio was the most useful quantitative index of cupping.
对300例高眼压症且疑似或确诊为慢性开角型青光眼患者的视盘照片进行杯盘比测量,并记录其视野情况。随着垂直杯盘比的增加,视野缺损的发生率也随之升高,杯盘比为0.70是判断是否存在视野缺损的一个特别有用的指标。杯盘比的大小与视野范围之间存在显著相关性。垂直杯盘比是杯盘比最有用的量化指标。
