Management of breakthrough vitreous hemorrhage from presumed extramacular subretinal neovascularization.

Three patients developed vitreous hemorrhage secondary to breakthrough bleeding from presumed extramacular subretinal neovascularization. In one patient, the vitreous hemorrhage cleared spontaneously. In two other patients, trans-pars plana vitrectomy was performed. All patients regained 20/30 vision or better. Residual peripheral retinal pigment epithelial atrophy, organized subretinal hemorrhage, and/or subretinal fibrous membranes were present in all patients. A definite extramacular subretinal neovascular membrane was identified in one patient. Ocular diseases associated with subretinal neovascularization are tabulated. Indications for trans-pars plana vitrectomy in patients with breakthrough vitreous hemorrhage secondary to presumed extramacular subretinal neovascularization are proposed.
