Fig. 2. Case is a 57-year-old man with a 15-year history of nonisulin dependent diabetes who complained of decreased vision in his right eye. Visual acuity was 20/40. Examination revealed clinically significant macular edema by slit lamp biomicroscopy using ETDRD criteria (A; Color Fig. 2). Laser photocoagulation was recommended and a fluorescein angiogram was obtained (B, C). Focal treatment was performed (D), and on follow-up examination 4 months later, resolution of the thickening was seen, with a visual acuity of 20/20. Because no further traetment was indicated, no further angiograms were performed. Serial follow-up examinations showed complete resolution of his macular edema without recurrence, and 2 years after treatment his visual acuity remained at 20/20 (E). Comment: This is an example of a patient who required fluorescein angiography after the initial decision to treat his diabetic macular edema had resolved and no further treatment was indicated, no additional fluorescein angiograms were needed.
