• We reviewed 14 consecutive cases of subretinal hemorrhage involving the macula, in which surgery to remove the hemorrhage was performed by the authors between February 1984 and January 1989. All patients underwent pars plana vitrectomy and internal subretinal hemorrhage drainage. The causes of subretinal hemorrhages in group 1 were primary rhegmatogenous retinal detachments (three eyes), complications from scleral buckling procedures (three eyes), traumatic retinal detachments (two eyes), and sickle cell retinopathy associated with anticoagulation therapy after a pulmonary embolus (one eye). Group 2 consisted of five eyes with massive subretinal hemorrhage associated with age-related macular degeneration. In group I, recurrent postoperative retinal detachment occurred in five eyes but reattachment was achieved in eight of the nine eyes, and final visual acuities were 20/400 or better in those eight eyes. In group 2, marked subretinal fibrosis occurred in two eyes. Although three eyes had improved visual acuities, final visual acuities were 5/200 or worse in all five eyes.
