Abstract

While age-related maculopathy (ARM) and diabetic retinopathy (DR) are distinct clinical entities, they are similar insofar as both can produce marked visual loss. In particular, both can produce an acquired blue-yellow, or tritan, color defect on a standardized test such as the Farnsworth-Munsell 100-Hue Test (1,2). In this study, we used a saturation discrimination test to compare the color vision of patients with early signs of ARM and patients showing early signs of DR.
