Is Central Retinal Vein Occlusion (CRVO) due to hereditary ischemia risk factors?

Abstract

Introduction: Central retinal vein occlusion is one of the major causes of severe vision impairment and blindness in adults. Case presentation: We present a case of unilateral ischemic central retinal vein occlusion in a 33-year-old man without any acquired ischemia risk factors and glaucoma. Laboratory tests including homocysteine and lipoprotein (a) were increased. Conclusion: Our case illustrates an interesting presentation of unilateral ischemic central retinal vein occlusion, without main risk factors. Thrombophilia screening may be considered in selected cases.
