“…58 Telescreening approaches may include temporary mobile DR screening services whereby teams visit communities for short periods, centralized image analysis, or a combination of both. [59][60][61][62] Telescreening is usually cheaper and preferred by patients compared with traditional surveillance techniques. 63 Telescreening has been used in different screening programs, including the OPHDIAT® program in France; 59 the Remote Outreach DR Screening Service in Australia, which increased screening rates four-fold; 64 and the Sankara Nethralaya Teleophthalmology Project (SNTOP) and Aravind Teleophthalmology Network (ATN) in India, which estimated that 150 patients could be screened per day, with a single ophthalmologist making the final diagnoses remotely.…”

Diabetic retinopathy (DR) is a microvascular complication of diabetes with a prevalence of ~35%, and is one of the leading causes of visual impairment in people of working age in most developed countries. The earliest stage of DR, non-proliferative DR (NPDR), may progress to sight-threatening DR (STDR). Thus, early detection of DR and active regular screening of patients with diabetes are necessary for earlier intervention to prevent sight loss. While some countries offer systematic DR screening, most nations are reliant on opportunistic screening or do not offer any screening owing to limited healthcare resources and infrastructure. Currently, retinal imaging approaches for DR screening include those with and without mydriasis, imaging in single or multiple fields, and the use of conventional or ultra-wide-field imaging. Advances in telescreening and automated detection facilitate screening in previously hard-to-reach communities. Despite the heterogeneity in approaches to fit local needs, an evidence base must be created for each model to inform practice. In this review, we appraise different aspects of DR screening, including technological advances, identify evidence gaps, and propose several studies to improve DR screening globally, with a view to identifying patients with moderate-to-severe NPDR who would benefit if a convenient treatment option to delay progression to STDR became available.
