To report a case of severe reversible vision loss in a woman with a 7-year history of anorexia nervosa, purging type, alcohol abuse and a severely restricted, vitamin-deficient diet.
Psychiatric, ophthalmologic, and medical records were reviewed, and a literature search was performed on visual complications associated with anorexia nervosa and malnutrition.
Ophthalmologic complications of malnutrition are rare but include both oculomotor and visual sensory disturbances. Thiamine deficiency can cause both types of disorders. Vitamin B12 and folate deficiencies are typically associated with optic neuropathy. Clinicians treating eating disorders should be aware of the potential for vitamin deficiencies and associated visual loss in patients with anorexia nervosa. This case highlights the importance of a detailed dietary history to guide vitamin rehabilitation and to minimize or reverse nutritional visual loss.
报告一例严重可逆性视力丧失的病例，该患者为一名女性，患有神经性厌食症（贪食型）7 年，同时伴有酗酒和严重的限制、缺乏维生素的饮食。
对该患者的精神科、眼科和医疗记录进行了回顾，并对与神经性厌食症和营养不良相关的视觉并发症进行了文献检索。
营养不良的眼科并发症较为罕见，但包括眼球运动和视觉感觉障碍。硫胺素缺乏可引起这两种类型的疾病。维生素 B12 和叶酸缺乏通常与视神经病变有关。治疗饮食失调的临床医生应该意识到维生素缺乏症以及神经性厌食症患者的相关视觉丧失的可能性。该病例强调了详细的饮食史对指导维生素康复以及最大限度减少或逆转营养性视力丧失的重要性。
