Abstract

A simple technique is described for assessing the sensitivity of the human visual system to gratings at threshold contrast. The technique has advantages for clinical use in that it is (1) inexpensive, (2) quick to administer, (3) portable, and (4) relatively free from bias. Forty-two diabetic patients and 84 normal controls have been tested. Fifteen diabetic patients (6/20 with retinopathy and 9/22 without) had test scores more than two standard deviations below the norm for age-matched controls.

摘要

本文描述了一种用于评估人类视觉系统对阈值对比度光栅敏感度的简单技术。该技术在临床应用中有以下优点:(1)成本低,(2)实施快速,(3)便于携带,(4)相对无偏差。已对42名糖尿病患者和84名正常对照者进行了测试。15名糖尿病患者(20名中有视网膜病变的6名,22名无视网膜病变的9名)的测试得分比年龄匹配对照组的正常水平低两个标准差以上。
