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
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
And in some of those individuals,
the floaters are serious.
