A Huge Floater!

Posterior Vitreous Detachment (PVD) is common and occurs when the vitreous gel that fills the eye separates from the retina.    Symptoms include floaters and flashes in your vision.  In this photo, the patient had cataract surgery, so the floater is more visible.

Symptoms usually subside over several weeks.   Rarely, a PVD can develop into something more serious, like a  retinal detachment or epiretinal membrane.
