I'm Jerry Sebag, professor of clinical optomology at the Doheny Eye Institute and founding director of the VMR Institute for Vitreous Macula Retina in Southern California. We'll now consider the visual impact of a posterior vitreous detachment that is not anomalous in part 2.

The last topic that I'm going to be discussing is a consequence of posterior vitreous detachment that has previously been considered an innocuous event but is currently being reconsidered in terms of a disease. Recall that posterior vitreous detachment requires liquefaction of the gel, vitreous, as well as dehiscence at the vitreo-retinal interface in order for the poster vitreous detachment to be innocuous. And by innocuous, what we're referring to is that there are none of the anomalous changes that we've just considered that result in retinal tears and detachments, vitreo-macular traction syndrome, macular holes, and macular pucker. In the absence of all of those manifestations of anomalous PVD, it has previously been considered that a PVD is innocuous. However many patients experience floaters. And in some of those individuals, the floaters are serious.
