In conjunction with optical equipment and lenses, the power of a laser can be focused on the retina to achieve controlled scarring or “coagulation”. Laser can be used to seal leaky blood vessels, treat retinal tears or holes, and help control the bleeding associated with diabetic retinopathy. There are a variety of different laser procedures but all can be performed in the office usually with a simple numbing eye drop. Typical laser sessions may be as short as two minutes or as long as 30 minutes depending on the retinal disease. Common laser procedures are performed for macular edema (due to diabetes or a retinal vein occlusion), retinal tears, retinal detachments, and proliferative diabetic retinopathy. Laser photocoagulation is performed by all of our physicians in all of our offices.
