Use of digitized fluorescein angiogram system to guide laser treatment of diabetic macular edema: a new technique.

We describe our technique to guide laser treatment in diabetic patients with clinically significant macular edema using a digitized fluorescein angiogram system. A pretreatment red-free photograph overlaid on a fluorescein angiogram is processed with the aid of the digitized fluorescein angiogram system in order to include all the important traces on it. The processed red-free image is used by the surgeon as a guide to the laser photocoagulation, improving treatment accuracy and safety for patients with diabetic macular edema. Copyright 2003 S.
