ABSTRACT

A 44-year-old man was evaluated for bilateral progressive visual loss and diagnosed with vitamin B₁₂ deficiency optic neuropathy. Optical Coherence Tomography Angiography features of optic nerve and macula showed a decrease in peripapillary and macular vessel density that correlated well with the areas of retinal nerve fibre layer thinning seen on OCT. Further studies are needed to evaluate the role of this new technology in the evaluation of toxic and metabolic optic neuropathy.
