Posterior Vitreous Detachment (PVD)

What exactly does PVD (posterior vitreous detachment) mean?

When the gel that covers the eyeball separates from the retina, it results in posterior vitreous detachment (PVD). The thin layer of nerve tissue that lines the back of the eyeball is called the retina. It's in charge of recognizing light and converting it into pictures.

Causes

Due to aging and normal wear and tear, the vitreous gel that fills the eye condenses (shrines) with time. The gel eventually runs out of space in the eye's vitreous cavity, which is positioned at the very back of the eye cavity and stays the same size throughout maturity. As a result, the gel separates from the retina.

Up until the PVD is finished and the vitreous gel is solely connected to the retina at the vitreous base, the vitreous gel continues to compress over the next one to three months.

The space between the condensed vitreous gel and the retina is filled with clear vitreous fluid.

The symptoms of a PVD are often modest if it develops slowly, consistently, and uniformly. However, the PVD can rupture the retina or a retinal blood artery if the forces of separation are severe or concentrated in one area of the retina, or if there is an abnormal adhesion (sticking together) between the vitreous gel and the retina (such as lattice degeneration). When PVD is made more severe by a retinal tear or vitreous haemorrhage, flashes and floaters are often more noticeable. These abnormalities can develop into more serious problems like epiretinal membrane or retinal detachment, which can impair vision permanently.

However, nearly 85% of individuals with PVD never encounter difficulties, and the flashes and floaters often go away in 3 months.
