<unk>  is a self-limiting disease that may affect both type 1 and type 2<unk>  patients. Unilateral or bilateral optic disc edema may occur. The exact etiology, pathogenesis and mechanism of the disc edema is unknown. Theories suggest that the dis edema is due to retinal vascular leakage into and surrounding the optic nerve and disruption of axoplasmic flow resulting from microvascular disease of the optic nerve head. Edema is seen in and around the optic nerve head also. Intraretinal hemorrhages and hard exudates may also be seen.
