Nonmydriatic widefield retinal imaging with an automatic white LED confocal imaging system compared with dilated ophthalmoscopy in screening for diabetic retinopathy

Abstract Purpose: To compare nonmydriatic montage widefield images with dilated fundus ophthalmoscopy for determining diabetic retinopathy (DR) severity. Materials and methods: In this prospective, observational, cross-sectional study, patients with a previous diagnosis of diabetes and without history of diabetes-associated ocular disease were screened for DR. Montage widefield imaging was obtained with a system that combines […]

Comparison of true-color wide field confocal scanner imaging with standard fundus photography fordiabetic retinopathy screening

Abstract Background: Screening of diabetic retinopathy (DR) reduces blindness by early identification of retinopathy. This study compares DR grades derived from a two-field imaging protocol from two imaging platforms, one providing a single 60-degree horizontal field of view (FOV) and the other, a standard 45-degree FOV. Methods: Cross-sectional study which included 1257 diabetic patients aged […]

Inter-Device Comparison of Blue-Light Autofluorescence in Optic Disc Drusen

Abstract Purpose: Monochromatic blue-light fundus autofluorescence has proven to be particularly useful for the detection of optic disc drusen (ODD). The aim of this study was to investigate how accurately novel confocal scanners can detect ODD by means of color fundus and autofluorescence images. Methods: Images were taken in 20 consecutive patients’ eyes with funduscopically […]

A comparison between a white LED confocal imaging system and a conventional flash fundus camera using chromaticity analysis

Abstract Background: Conventional flash fundus cameras capture color images that are oversaturated in the red channel and washed out in the green and blue channels, resulting in a retinal picture that often looks flat and reddish. A white LED confocal device was recently introduced to provide a high-quality retinal image with enhanced color fidelity. In […]
