Fluorescein angiography (FA) images in the patient before (a) and after (b) oral acetazolamide therapy obtained at 2 min after fluorescein injection. Dye leakage in both the macular and mid-peripheral areas is decreased by the treatment, as demonstrated by remarkably decreased leakage in the macula and more definite demarcation of hyperfluorescent lesion in the mid-peripheral retina
