Diabetic retinopathy (DR) at risk of vision loss (referable DR) needs to be identified by retinal screening and referred an ophthalmologist. Existing automated algorithms have mostly been developed from images acquired with high cost mydriatic cameras cannot applied in the settings used most low- middle-income countries. In this prospective multicentre study, we a deep learning system (DLS) that detects referable DR using handheld non-mydriatic fundus camera non-technical field workers 20...
