title: Toxic amblyopia associated with Crohn's disease.
abstract: 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.
