Color photograph of a macula exhibiting diabetic macular edema. Microaneurysms and intra-retinal hemorrhages are visible as red spots. Retinal thickening is visible as a loss of granularity combined with subtle changes in coloration and is best visualized in stereo using slit lamp biomicroscopy. Lipid exudates are visible as yellow streaks or spots, often distributed in a circinate pattern around leaking microaneurysms.
