Unilateral branch retinal vein occlusion with vitreous hemorrhage mimicking Terson's syndrome.

We report a case of unilateral traumatic vitreous hemorrhage following injury to the anterior cranium. A 55-year-old female presented with gradual loss of vision in her left eye following trauma to the anterior cranium. Funduscopy revealed fresh vitreous hemorrhage. Conservative management was futile with further visual deterioration over the next 2 weeks. During pars plana vitrectomy, fresh retinal hemorrhages were noted along the superotemporal (ST) vein suggesting bleed due to vein rupture. Postoperative fundus fluorescein angiography indicated ST branch retinal vein occlusion. Since trauma can be an inciting factor for both, this case could be a variant of Terson's syndrome.
