OPTIC DISC CUPPING IN DIABETES

这项研究旨在测量视盘拔火罐的照片 参与调查的2990名糖尿病患者的视盘 1980-1982年威斯康星州糖尿病视网膜病变及世卫组织流行病学研究 将在1984-1986年间再次出现，在381名患有糖尿病的非糖尿病受试者中 并且将在相同的时间间隔内被看到。将进行测量 使用标准化的技术。将执行双重评分，并 评分员将掩盖受试者的糖尿病状况。放坡 将与记录的眼压相关 眼底照相时间。可能的混淆的影响 将对变量进行评估。纵向数据将允许 定量评估眼内压对儿童眼压的预测价值 视盘拔罐的变化。比较糖尿病患者和糖尿病患者的发病率 这项研究和其他人群中的非糖尿病患者将允许我们 以确定糖尿病患者是否表现出患病率增加 更大的视盘拔火罐。 糖尿病患者样本和年龄匹配的非糖尿病患者组 人们将接受戈德曼视野测试。视力检查 视神经的视野、眼压和立体摄影将 由两名眼科医生以蒙面的方式独立进行评估。 这将提供对糖尿病患者青光眼风险的估计，如 与非糖尿病患者相比。

The study is designed to measure optic disc cupping in photographs of the optic discs obtained on 2990 diabetic persons who participated in the Wisconsin Epidemiologic Study of Diabetic Retinopathy in 1980-1982 and who will be seen again in 1984-1986, and in 381 non-diabetic subjects who were and will be seen during the same time intervals. Measurements will be made using a standardized technique. Double gradings will be performed and graders will be masked as to the diabetes status of the subjects. Gradings will be correlated with intraocular pressures that were recorded at the time of fundus photography. The influence of possible confounding variables will be assessed. The longitudinal data will permit a quantitative estimate of the predictive value of intraocular pressure for change in optic disc cupping. Comparing rates in the diabetic persons and non-diabetic persons in this study and in other populations will allow us to determine whether diabetic persons demonstrate an increased prevalence of greater optic disc cupping. A sample of diabetic persons and an age matched group of non-diabetic persons will have Goldmann visual field testing. Examination of the visual fields, intraocular pressure and stereophotographs of the optic nerves will be assessed by two ophthalmologists independently, and in masked fashion. This will provide an estimate of the risk of glaucoma in diabetics as compared with non-diabetic persons.
