To evaluate the diagnostic capability of a smartphone handset compared with a standard office computer workstation for teleophthalmology fundus photo assessments of diabetic retinopathy.
Eligible, consenting participants' fundus images were acquired using a non-mydriatic camera. These images along with other medical data were transmitted 20 miles away through the Internet (gold standard) and also through an iPhone(®) (Apple, Cupertino, CA) to two ophthalmologists, who independently compared the images.
The κ coefficient between the gold standard workstation display and iPhone images to detect retinopathy-related changes for both readers was more than 0.9. The image quality of the iPhone was scored high by the ophthalmologists.
Ophthalmic images transmitted through both smartphone and Internet techniques match well with each other. Despite current limitations, smartphones could represent as a tool for fundus photo assessments of diabetic retinopathy. Further studies are needed to investigate the economic and clinical feasibility of smartphones in ophthalmology.
评估智能手机与标准办公电脑工作站在糖尿病视网膜病变远程眼底照相评估方面的诊断能力。
使用非散瞳相机获取符合条件并同意参与的患者眼底图像。这些图像以及其他医疗数据通过互联网（金标准）传输 20 英里（约 32 公里），同时也通过 iPhone（®）（苹果公司，加利福尼亚州库比蒂诺）传输到两位眼科医生处，他们独立比较这些图像。
两位阅读者的金标准工作站显示与 iPhone 图像之间检测与视网膜病变相关的变化的 κ 系数均大于 0.9。眼科医生对 iPhone 的图像质量评价较高。
通过智能手机和互联网技术传输的眼科图像彼此匹配良好。尽管存在当前的局限性，智能手机可以作为糖尿病视网膜病变眼底照相评估的工具。需要进一步研究来探讨智能手机在眼科领域的经济和临床可行性。
