A deep learning-based smartphone app for real-time detection of retinal abnormalities in fundus images

Abstract

This paper presents the real-time implementation of two deep neural networks, which are trained for detection of eye retina abnormalities, on smartphones as an app. This app provides a low-cost and universally accessible alternative to fundus cameras since smartphones are widely available and they can be fitted with lenses that are commercially available for examination of the retina. The process of training two convolutional neural networks for retinal abnormality detection based on two publicly available datasets is discussed. Furthermore, it is shown how a smartphone app, both Android and iOS versions, are created from these trained networks. The results obtained indicate that it is possible to carry out the detection of retinal abnormalities on smartphones in an on-the-fly manner as retina images get captured by their cameras in real-time.
