Posterior Vitreous Detachment It is a separation of the posterior vitreous cortex from the neurosensory retina - the vitreous collapses anteriorly towards the vitreous base. Initially there is liquefaction and syneresis → rupture in the posterior hyaloid → liquified vitreous flows out → separates the posterior hyaloid from the retina Begins as a partial PVD at the perifoveal region → progresses to optic disc and formation of Weiss ring Vitreous traction at firm sites of adhes
