Validation of Smartphone-Based Retinal Photography for Diabetic Retinopathy Screening.

Backround And Objective: Screening for diabetic retinopathy (DR) is cost-effective when compared with disability loss for those who go blind in the absence of a screening program. We aimed to evaluate the sensitivity and specificity of a smartphone-based device for the screening and detection of DR.

Patients And Methods: A cross-sectional study of 220 patients with diabetes (440 eyes, all patients age 25 years or older) was completed.
