PVD -> Retinal Detachment?

Given PVD symptoms like peripheral flashes, how likely is it that you
won't get retinal detachment, and what are the signs that things are
settling down without detaching retina (only Posterior Vitreous
Detachment)? This case involved someone with risk characteristics,
suddenly getting couple hours of strong light flashes (even with closed
eyes) but not much increase in floaters.

Puhleeeeze, pretty please fill in some info instead of deferring
entirely to obvious urgent reccomendations to see eye doc asap.
Gravity of the danger is understood: http://www.vrmny.com/PVD.htm , but
need to be a prepared consumer of medical services, which can be an
excruciatingly slow and uncooperative player in this case.
Additionally, the standard dilation exam has proved infeasible in past
due to particular patient issues; what about this ultrasonography
approach? Thanks!

 

Usually the odds are in your favor that a pvd will not develop into a
retinal tear and detachment. I see pvd's almost daily and, I think, out
of the last 20 pvd's I've seen , one had a horseshoe tear. But it's
kind of weird, you can go weeks without seeing a pvd with a tear
and suddenly have two back to back.

Many times, unless one has a tear that develops into a
detachment involving the macula, the symptoms can be
minimal.
