A 71-year-old patient presented with failing vision. She was a life-long smoker who had suffered from Crohn's disease for at least 13 years and had vitamin B12 malabsorption which failed to correct with intrinsic factor. It is suggested that toxic amblyopia be considered in any patient with visual impairment associated with terminal ileal disease.
一名71岁的患者出现视力下降。她是一名终身吸烟者，患有克罗恩病至少13年，存在维生素B12吸收不良，且补充内因子后仍未纠正。建议对于任何患有与末段回肠疾病相关视力损害的患者，都应考虑中毒性弱视。
