ABSTRACT
Sixty-one patients (62 eyes) with vitreous hemorrhage were studied. None were associated with diabetic retinopathy or perforating injuries and all required surgical treatment. The patients had dense vitreous hemorrhage with preoperative visual acuity of counting finger or worse in 55 eyes (88.7%). After the operation, a final visual acuity of 6/60 or better was found in 32 eyes (51.6%). The common causes of vitreous hemorrhage were subretinal neovascularization, blunt trauma, branch retinal vein occlusion, post-cataract extraction, retinal detachment with tears, and retinal vasculitis. There was no association between the postoperative visual outcome and either the preoperative visual acuity or the duration of vitreous hemorrhage. The pathological change at the macular area was the main factor which influenced the visual outcome.
