Unilateral optic disc edema in a patient with acute lymphocytic leukemia -: A case and review of the literature

A young male complained of acute left-eye visual loss. The right eye was normal. Only hand motions were seen with the left. The dilated fundus showed mild optic disk elevation, blurred margins, tortuous vessels, retinal vascular sheathing, and flame-shaped hemorrhages. Laboratory exam revealed acute lymphocytic leukemia. Following chemotherapy and radiotherapy, disk swelling and retinal changes resolved and visual acuity improved.
