[Therapy of preretinal macular hemorrhages]

Within the first 3 to 4 days after occurrence of a premacular subhyaloid hemorrhage the posterior vitreous boundary layer may be lacerated by argon laser coagulation in such a way, that the blood floats into the vitreous body, where it is absorbed within a few weeks. Older premacular hemorrhages under an intact vitreous boundary layer, typically green-white in color have to be treated by more invasive vitreo-surgical procedures.
