It usually presents as unilateral optic disc edema with cotton wool spots and hemorrhage in the peripapillary region. As it may be due to many autoimmune and inflammatory causes, a thorough systemic evaluation of the patient is warranted. In this case report we describe a bilateral, simultaneous papillophlebitis case thought to be related to hyperhomocysteinemia secondary to C677T polymorphism of methylenetetrahyrofolate reductase enzyme.en10.4274/tjo.77785info:eu-repo/semantics/openAccessPapillophlebitishyperhomocycte nemiamethylenetetrahyrofolate reductase mutationArticle46418218528058155N/AWOS:000393279900008N/A
