A 44-year-old man was evaluated for bilateral progressive visual loss and diagnosed with vitamin B 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.
一名44岁男性因双眼进行性视力丧失接受评估，被诊断为维生素B缺乏性视神经病变。视神经和黄斑的光学相干断层扫描血管造影特征显示视乳头周围和黄斑血管密度降低，这与光学相干断层扫描（OCT）上所见的视网膜神经纤维层变薄区域密切相关。需要进一步研究来评估这项新技术在中毒性和代谢性视神经病变评估中的作用。
