Diabetic Macular Edema
You should look at the Normal Retina photo first for comparison. This photo shows yellow lipid around the macula, the center of the picture. The lipid is a sign that the blood vessels of the retina are leaking serum into the tissue. The retina can pump the salt and water out, but the lipids stay in the tissue longer, giving this picture. Laser treatment or injections of a steroid called triamcinolone into the vitreous of the eye can be used to treat this condition. Tight control of blood sugar, blood pressure, and serum lipids is the foundation for successful management.
