Portable Smart Healthcare Approach for Earlier Stage Eye Tests for Diabetic Retinopathy Detection

摘要

High-quality, wide field retinal imaging is an effective method of retinal disease screening that is preventable and endangers vision. Retinal smartphone-based cameras promise to increase retinal imagery access, but variable image quality and restricted field of view can restrict their usefulness. This article discusses how to build a fundus camera based on smartphones that is capable of photographing the central retina and the peripheral retina up to the plana pars. It is a cost-effective alternative to the fundus camera.
