How do you treat macular hemorrhage?
A second treatment option is pneumatic displacement of macular hemorrhage with or without pretreatment with intravitreal TPA. In one recent study, 5 patients with subretinal hemorrhage (1 from a retinal artery macroaneurysm and 4 from AMD) were treated with pneumatic displacement of blood without the use of TPA.
