Abstract
To assess the efficacy and safety of intravitreal injection of recombinant tissue plasminogen activator and sulfur hexafluoride gas for displacement of subretinal hemorrhages in patients with age-related macular degeneration. The authors injected 25 microg of recombinant tissue plasminogen activator and 0.5 mL sulfur hexafluoride gas intravitreally in 11 patients with subretinal hemorrhages of less than 3 weeks duration. Anatomic and functional results were evaluated. Displacement of subretinal blood was successful within the first week after surgery in 10 of 11 patients. This was accompanied by visual improvement in eight patients. After 1 year, visual acuity was better than before surgery in five patients. Diagnosis of a choroidal neovascularization by fluorescein angiography was possible in all patients, and was treated with laser photocoagulation in five. The authors observed no adverse effects of treatment. Recombinant tissue plasminogen activator and gas effectively displace subretinal blood in patients with age-related macular degeneration. Randomized studies are necessary to prove the benefit of this simple and safe method in patients with subretinal hemorrhage due to age-related macular degeneration.
