Age-related macular degeneration and vitreous hemorrhage

Age-related macular degeneration led to vitreous hemorrhage (VH) in six eyes of four patients. Macular involvement was bilateral in three patients and fluorescein angiography performed before VH showed extensive subretinal hemorrhage in the macular region in all eyes. We examine the possible causal mechanisms of VH resulting from age-related macular degeneration. Local risk factors, as outlined in our series by fluorescein angiography, are discussed and systemic risk factors are considered. Three out of the six eyes underwent pars plana vitrectomy for removal of intravitreal blood, and had severe inflammatory reactions in the postoperative period. In the three non-operated eyes spontaneous reabsorption of VH was observed at the end of follow-up.
