AB  - Isolated optic neuropathy due to folate deficiency is rarely reported. Poor dietary practices, malabsorption, and tobacco/alcohol abuse are usually responsible. We examined a patient with blinding optic neuropathies and isolated folic acid deficiency. Visual acuity recovered after folate replacement. At the same time, serological investigation revealed high ferritin and iron saturation levels with negative genetic markers for haemochromatosis consistent with the diagnosis of iron overload syndrome. There are no reports of blindness associated with iron overload syndrome.
