Case 2. Cystoid macular edema before and after treatment. A, hindus photograph showing hard exudate inferior to the fovea. B, fluorescein angiogmphy showing diffuse leakage in the superior macula. C, large central cysts and intraretinal hard exudate are observed on optical coherence tomography (OCT). D, OCT topographic map displays increased macular thickness throughout the macula, especially in the area of fluorescein leakage. E, OCT topographic map obtained 4 months after focal laser photocoagulation showing a decrease in macular thickness.
