The value of the Canon CR3-45NM non-mydriatic fundus camera in screening for diabetic retinopathy has been assessed in two ethnic groups, namely, 45 Indian and 40 European diabetic patients. There was 72% agreement between ophthalmoscopy by an ophthalmologist and the photographic assessment, and 100% agreement on clinically important lesions requiring treatment. However, peripheral retinal lesions, seen on ophthalmoscopy but lying outside the photographic field, occurred in 4% of eyes. 6% of photographs were totally unassessable and an additional 12% were only partially assessable. The prevalence and severity of retinopathy was similar in Indian and European patients. The advantages and disadvantages of the non-mydriatic camera in screening for diabetic retinopathy are discussed.
已在两个种族群体(即45名印度糖尿病患者和40名欧洲糖尿病患者)中评估了佳能CR3 - 45NM免散瞳眼底相机在筛查糖尿病视网膜病变方面的价值。眼科医生的检眼镜检查与摄影评估之间的一致性为72%,对于需要治疗的具有临床重要意义的病变,一致性为100%。然而,检眼镜检查发现但位于摄影视野之外的周边视网膜病变在4%的眼睛中出现。6%的照片完全无法评估,另有12%仅部分可评估。印度和欧洲患者视网膜病变的患病率和严重程度相似。讨论了免散瞳相机在筛查糖尿病视网膜病变中的优缺点。
