The foveal photopic threshold for Landolt ring discrimination and the paramacular scotopic threshold has been monocularly measured in 27 diabetic patients, 30 to 50 years old, without funduscopic retinal alterations, and compared with similar thresholds collected from 17 healthy age matched subjects. About 0.3 log threshold elevation for both photopic and scotopic functions were documented in the diabetic group, suggesting a functional impairment before visible retinopathy occurred. The threshold loss was not correlated with the diabetes longevity.
对27名年龄在30至50岁、无眼底视网膜病变的糖尿病患者单眼测量了用于辨别兰多尔特环的中央凹明视觉阈值和黄斑旁暗视觉阈值，并与17名年龄匹配的健康受试者收集的类似阈值进行了比较。糖尿病组的明视觉和暗视觉功能阈值均升高约0.3对数，这表明在可见视网膜病变出现之前就存在功能损害。阈值损失与糖尿病病程无关。
