Diabetic retinopathy

In diabetic retinal disease, vascular neoplasms as well as retinal areas not supplied with blood and edema can be treated by laser coagulation. Laser coagulation creates circumscribed, well-dosed scars in the retinal tissue. Focal laser coagulation, for example, treats fluid accumulation (edema) at the site of sharpest vision. In panretinal laser coagulation, areas of the retina that are not supplied with blood are coagulated.
