Purpose: To evaluate the ability of smartphone-based imaging to grade diabetic retinopathy (DR) compared to dilated ophthalmic examination by retinal specialist ophthalmologists. Methods: A subset of 120 diabetic patients underwent dilated examination and smartphone ophthalmoscopy. The smartphone was equipped with a compact add-on that filtered and delivered the smartphone’s LED light coaxially to the camera, allowing a clear and convenient view of the retina. Results: There was exact agreement in 213 eyes (88.8%) and agreement within 1 step in 237 (98.8%). Weighted kappa was 0.80 ± 0.04. Conclusion: Smartphone ophthalmoscopy showed near-perfect agreement with dilated ophthalmic examination in the detection of DR
