Vitreous Hemorrhage Complicating Laser-Induced Chorioretinal Anastomosis for Central Retinal Vein Occlusion

To report a severe complication of laser chorioretinal anastomosis for central retinal vein occlusion. Case report. In the right eye of a 62-year-old woman with nonischemic central retinal vein occlusion, retinal neovascularization at the laser chorioretinal anastomosis site caused dense secondary vitreous hemorrhage. Vitreous hemorrhage prevented laser panretinal photocoagulation for subsequent iris neovascularization, necessitating vitrectomy surgery to clear the hemorrhage and allow the treatment. Laser chorioretinal anastomosis can result in severe vitreous hemorrhage and complicate efforts to manage later sequelae of central retinal vein occlusion.
