Comparisons of Visibility of Two-Color (RG) to Three-Color (RGB) Ultra-Widefield Images for Ten Types of Fundus Lesions.

ABSTRACT:

Purpose

To compare the visibility of fundus lesions between RGB and RG images obtained with an ultra-widefield (UWF) fundus imaging device (Optos) for 10 types of fundus lesions.

Methods

UWF images from 30 patients representing 10 types of fundus lesions were analyzed: vessel sheathing, optic disc cupping, cotton wool spots, epiretinal membrane, laser photocoagulation scars, retinal drusen, retinal hemorrhage, retinal/choroidal detachment, chorioretinal atrophy, and macular degeneration. Three images of each type of lesion were used, and 26 board-certified ophthalmologists compared them. The raters compared the visibility of lesions on a five-point scale: RG significantly better = -2; RG slightly better = -1; equal = 0; RGB slightly better = +1; and RGB significantly better
