简介：营养性视神经病变并不常见，可能与逐渐视力丧失和视神经萎缩或突然视力丧失和视盘肿胀有关。病例介绍：一名 44 岁女性有 4 周的进行性视力丧失病史，并被发现患有双侧球后视神经病变。没有发现其他临床异常。调查显示叶酸严重缺乏，而维生素 B12 水平正常。她的酒精和烟草摄入量适中，随后通过口服补充剂纠正叶酸水平，导致她的视力得到改善。结论：该病例凸显了叶酸缺乏症的不寻常表现，可能会向全科医生提出。
INTRODUCTION: Nutritional optic neuropathies are uncommon and can be associated with gradual visual loss and optic atrophy or sudden vision loss and optic disc swelling.CASE PRESENTATION: A 44-year-old woman presented with a 4-week history of progressive visual loss and was noted to have bilateral retrobulbar optic neuropathy. No other clinical abnormality was noted. Investigations revealed severe folate deficiency with normal vitamin B12 levels. Her alcohol and tobacco consumption was moderate and subsequent correction of folate levels with oral supplementation has led to improvement in her visual acuity.CONCLUSION: This case highlights an unusual presentation of folic acid deficiency that may present to the general physician.
