title: Loss of vision as a presenting sign of cobalamin deficiency: An eye-opener.
abstract: We describe a patient who presented with loss of vision that turned out to be caused by cobalamin deficiency. Both her vision and her visual field improved upon supplementation of cobalamin. It is, therefore, important to consider cobalamin deficiency as a treatable cause of loss of vision.
