Optic neuropathy in vitamin B12 deficiency.
There are many neurological manifestations of vitamin B(12) deficiency. Optic neuropathy is a rare, but important, manifestation of vitamin B(12) deficiency that should be suspected in patients with risk factors for malnutrition. We present a case of a 68-year-old male who presented with bilateral decreased central vision for months and was found to have a low vitamin B(12) level. After a few months, his vision improved with parenteral vitamin B(12) supplementation. Vitamin B(12) optic neuropathy is a reversible, treatable cause of vision loss and may be a harbinger for other manifestations of the disease.
