A 30-YEAR-OLD white man with a 17-year history of insulin-dependent diabetes mellitus noted decreased vision for 1 month. He denied any history of ocular problems or surgery. At examination, his best-corrected visual acuity was 20/60 OD and 20/60-1 OS. Biomicroscopy revealed proliferative diabetic retinopathy with foveal neovascularization in both eyes (Figure 1). Optical coherence tomography and fluorescein angiography were performed (Figure 2 and Figure 3). Panretinal photocoagulation was initiated in both eyes.
