Laser Therapy

Laser photocoagulation is the mainstay treatment for diabetic macular edema. It is the process of sealing leaking blood vessels, by focusing laser, to stop excess accumulation of fluid in the macula. DME is characterized by microaneurysms, small protuberances in the blood vessels of the retina. During green laser therapy, a laser beam is targeted on the microaneurysms. Green laser therapy also improves the supply of oxygen inside the retina and reduces the formation of new abnormal blood vessels.
