Purpose: To report a case of nutritional optic neuropathy due to folic acid deficiency and who recoverd from oral supplementation with folic acid.
Case summary: A 45-year-old man was referred to our hospital because of visual disturbance and color vision on the both eye without pain. There were no abnormal findings in the anterior segment and retina. An afferent pupillary defect was found in the left eye. Visual field examination showed central scotoma in both eyes and total color blindness on Hahn color vision test. The patient had a history of chronic alcoholism and had not eaten often recently. The folic acid level was decreased in the blood and after oral folic acid supplementation, visual acuity and visual field recovered after 6 weeks.
Conclusions: We report a new case of nutritional optic neuropathy due to folic acid deficiency and who recovered from oral supplementation with folic acid.
