Subject Vitamin B12 Deficiency; Optic Neuropathy; Bilateral Centrocecal Scotoma; Superoxide Dismutase; Cyanocobalamin
Description Vitamin B12 deficiency can cause an optic neuropathy characterized by bilateral centrocecal scotomas. The mechanism for this is not well understood. In 2009, another group demonstrated that vitamin B12 scavenges superoxide as effectively as superoxide dismutase (SOD). Our prior work showed that retinal ganglion cells (RGC) axotomy induced a burst of superoxide that then led to RGC death. We hypothesized that superoxide scavenging by cyanocobalamin, the most abundant vitamin B12 vitamer, would be neuroprotective, and studied this in vitro and in vivo.
