    Chronic changes from nonischemic central retinal vein occlusion (CRVO) in a 30-yearold woman with a history of diabetes mellitus and blurry vision for 2 months. Visual acuity is 20/25. A, Color fundus photograph of a mild nonischemic, or perfused, CRVO. Dilated retinal veins and retinal hemorrhages are present, as are scant macular exudates; however, a foveolar reflex is still present. B, Fluorescein angiography image at 22 seconds after injection reveals capillary telangiectasias and microaneurysms throughout the posterior pole. C, Late angiogram at 9 minutes reveals diffuse retinal staining and microaneurysms. D, OCT scan reveals mild cystic changes and microaneurysms but minimal retinal thickening.
