ABSTRACT

A 56-year-old man with a medical history of alcoholic cirrhosis presented with acute bilateral loss of vision. On admission, the patient had pale skin and low arterial pressure. Ophthalmic examination demonstrated a visual acuity of 6/9 in the right eye and the absence of light perception in the left. Automated perimetry revealed a superior altitudinal defect in the right eye. Optic disc swelling, flame-shaped hemorrhages, and several cotton-wool spots were evident in both eyes on fundoscopy. Lab results confirmed severe anemia. Following prompt correction of the anemia, the altitudinal defect remained unchanged. However, visual acuity in the right eye improved significantly in a few days. The potential association of anemia with both papilledema and non-arteritic anterior ischemic optic neuropathy (NA-AION) is discussed, with a focus on possible pathophysiological mechanisms. The necessity for routine anemia screening, encompassing complete blood count, serum iron, and vitamin B12 levels, and subsequent rapid correction in these patients, is emphasized.
