Different Findings in Red and Green Color Channels for Diabe
The researchers analyzed standard color fundus photographs obtained from 2,047 adult patients with diabetes. Ninety percent of patients identified themselves as racial/ethnic minorities (other than non-Hispanic white). The study was performed in a medically under-served group, most without access to routine eye care. For patients with diabetes, regular dilated eye examinations (at least once yearly) are recommended to detect early signs of diabetic eye disease.

One major finding in diabetic eye disease is macular edema (a fluid accumulation in the retina) resulting from leaky blood vessels in the back of the eye. This condition is a leading cause of vision loss among working-age adults with diabetic eye disease.

The retinal photographs showed clinically significant macular edema in 148 patients. Of these, 13 patients had a "cystoid" pattern of macular edema—a major cause of severe central vision loss. The researchers compared the findings on standard color fundus photographs with those of images divided into the red (long wavelength) and green (shorter wavelength) color channels. Twelve of the 13 patients with cystoid macular edema had a dark-colored fundus.
