Many vitreoretinal pathologies are increasingly related to abnormal posterior vitreoretinal relationships. Dynamic study of the posterior vitreous allows for identification of abnormal posterior vitreous detachment. This study is designed to characterize the acute symptomatic posterior vitreous detachment related to age and to observe the natural history to describe hypothetical adverse outcomes.
An inception cohort of patients with diagnosis of posterior vitreous detachment were followed during a mean follow-up of 5 years to describe the natural history and outcomes of abnormal posterior vitreous detachment.
One third of patients (38%) presenting with PVD have an incomplete PVD. Eleven out of 131 patients (8,3%) developed an epimacular membrane, 4 patients developed a retinal tear (3%), and 9 other patients developed a retinal tear in the fellow eye (6,8%). Adverse events were more likely to occur in patients who had an abnormal posterior vitreous adherences.
Epimacular membranes, and late retinal tears are late adverse outcomes related to symptomatic PVD.
