Diabetic Macular Edema & Focal Laser Photocoagulation
Advanced Background Solution
At this advanced stage, blood vessels leak fluid into the macular tissue of the retina, and other vessels (capillaries) stop carrying blood at all. The retina becomes swampy, causing vision problems such as blurring.
Most doctors us an argon laser, usually green, applying light in one spot (focal) or all around the retina (pan-retinal). Laser treatment seals new blood vessels, dries up the “swampy” retina, and may improve or stabilize vision.
