A 62-year-old man presented with sudden lower visual field defect. He had tarry stools two weeks before the initial visit. On ophthalmic examination, his best-corrected visual acuity was 1.2 in both eyes. Fundoscopy revealed diffuse optic disc swelling, which was more marked superiorly in both eyes. Goldmann perimetry revealed an inferior altitudinal visual field defect. On laboratory investigation, his hemoglobin and hematocrit were 7.7 g/dL and 22.7 %, respectively, and the level of serum iron was 17 µg/dL. A diagnosis of bilateral non-arteritic anterior ischemic optic neuropathy (NAION) was made. We considered that NAION might be due to intestinal hemorrhage. This case highlights the importance for clinicians to be aware of NAION develop after intestinal hemorrhage.
