Abstract

BACKGROUND AND OBJECTIVE: To report clinical feasibility of non-mydriatic ultra-widefield (NMUWF) imaging and determine the prevalence of peripheral retinal pathology in comparison to standard single-field imaging in a primary care setting. PATIENTS AND METHODS: Six hundred and thirty-Two subjects (1,260 eyes) who underwent NMUWF imaging during annual health screening from October 2015 through March 2016 were retrospectively identified. An automated algorithm processed the raw images into: (1) NMUWF image with mask/grid outline that delineates the center 45° field simulating standard single-field photograph and (2) single-field image comprising 45° posterior pole extracted from the corresponding NMUWF image. RESULTS: Mean age of patients was 59.6 years ± 7.5 years. Of the 1,260 eyes, 1,238 eyes (98.3%) were considered optimum for grading. NMUWF images detected peripheral retinal pathology in 228 eyes (18.4%) that were not visible on corresponding single-field images. CONCLUSIONS: NMUWF imaging is feasible in a primary care setting, allows improved visualization of peripheral retinal pathology, and may therefore be useful for telemedicine screening.
