To evaluate the use of non-mydriatic fundus camera as a screening modality for diabetic retinopathy in a sample of population in Riyadh, Saudi Arabia.
Patients coming, from April 2015 till September 2018, for their diabetic check up at the diabetic center clinics in King Abdul-Aziz University hospital were screened using a non-mydriatic fundus camera (NMFC). Photos were graded by retina specialist and compared to the findings of dilated fundus examination (DFE) by retina specialists.
The grading results of NMFC and DFE were compared and the overall sensitivity and specificity for detection of diabetic retinopathy within one grade of retinopathy was 98.7% and 80% respectively. The sensitivity for detection of sight threatening conditions such as proliferative diabetic retinopathy, severe non-proliferative diabetic retinopathy, and diabetic macular edema (by Ocular Coherence Tomography) was found to be 86.7%, 90.3% and 100% respectively; while the specificity was found to be 96.5%, 93%, and 100% respectively.
Non-mydriatic fundus camera has a high sensitivity and specificity in screening for diabetic retinopathy. It is a great screening tool, which is user friendly and can be operated by trained nurses in primary clinics during patient's regular routine diabetic checkups. It aids in early detection of sight threatening conditions which need urgent referral to ophthalmologists.
评估在沙特阿拉伯利雅得的一部分人群中，使用免散瞳眼底相机作为糖尿病视网膜病变筛查方式的效果。
对2015年4月至2018年9月期间前往阿卜杜勒-阿齐兹国王大学医院糖尿病中心诊所进行糖尿病检查的患者，使用免散瞳眼底相机（NMFC）进行筛查。照片由视网膜专家进行分级，并与视网膜专家进行散瞳眼底检查（DFE）的结果进行比较。
比较了NMFC和DFE的分级结果，在一个视网膜病变等级内检测糖尿病视网膜病变的总体敏感性和特异性分别为98.7%和80%。发现检测增殖性糖尿病视网膜病变、重度非增殖性糖尿病视网膜病变和糖尿病黄斑水肿（通过光学相干断层扫描）等威胁视力情况的敏感性分别为86.7%、90.3%和100%；而特异性分别为96.5%、93%和100%。
免散瞳眼底相机在糖尿病视网膜病变筛查中具有较高的敏感性和特异性。它是一种很棒的筛查工具，使用方便，经过培训的护士在基层诊所患者进行常规糖尿病检查时即可操作。它有助于早期发现需要紧急转诊给眼科医生的威胁视力情况。
