Abstract
Case reportAn alcoholic patient with loss of vision in his right eye and a peripapillar hemorrhage, who then presented with a venous thrombosis. Blood analysis revealed hyperhomocysteinemia with coagulation parameters within the normal range. In the follow-up he developed a bilateral optic neuropathy. DiscussionAn increase in homocysteine levels is common in alcoholics, and it has been considered a vascular risk factor. Folic acid and vitamins B6 and B12 deficiency may lead to hyperhomocysteinemia, as they participate in its metabolism. ConclusionsWhen presented with a retinal occlusive disease or ischemic optic neuropathy in young patients, coagulation disorders and elevated levels of homocysteine should be ruled out.
