In this case series, three patients with bilateral simultaneous BRVO due to hyperhomocysteinemia secondary to C677T polymorphism in the metilenetetrahydrofolate reductase enzyme are presented. All three cases were young and presented with unilateral sudden vision loss. Bilateral detailed fundus examination is important for the detection of asymptomatic retinal vein occlusion in the other eyes of young retinal vein occlusion patients.
