Letter to the Editor: Comment on Tsiogka Et al.’s “Compound Heterozygosity for the C6777T Mutation of the MTHFR Gene and the FII G20210A Mutation of the Prothrombin Gene in Sequential Bilateral Anterior Ischemic Optic Neuropathy”

Abstract

Dear Editor, I read with great interest the paper entitled “Compound heterozygosity for the C6777T mutation of the MTHFR gene and the FII G20210A mutation of the prothrombin gene in sequential bilateral anterior ischemic optic neuropathy” by Tsiogka et al.Citation1 The authors reported a case of bilateral, sequential non-arteritic anterior ischemic optic neuropathy (NA-AION) in a 52-year-old patient who was found to have mutations for the prothrombin and methylenetetrahydrofolate reductase (MTHFR) genes.
