Monkey 7 (laser vs normal). A, Left retina with a fresh laser lesion, extending from 4 to 10° temporal to the fovea, made by applying 20 spots at 200 mW. The lesion appearswhite from acute coagulation necrosis. B, Healed scar, 7 weeks later, after resorption of the edema.C, Retinal sections, cut at the levels indicated in the diagram. Although the injury is limited mostly to photoreceptor cell bodies and outer segments, there is some inner nuclear layer damage.Dark lines, running across the retinal layers, are folds in the paraffin sections.
