How do you check for posterior vitreous detachment?

How do you check for posterior vitreous detachment?

Posterior vitreous detachment is usually diagnosed with a dilated eye examination. However, if the vitreous gel is very clear, it may be hard to see the PVD without additional testing, such as optical coherence tomography (OCT) or ocular ultrasound (see Figure 2).

How do you know when PVD is complete?

When a PVD is “complete,” the examiner will classically observe a Weiss ring on exam (Figure 2). A “Weiss ring” is the circular peripapillary attachment that is visible within the vitreous after it has become detached from the optic nerve head.

When to see a specialist for posterior vitreous detachment?

In posterior vitreous detachment (PVD), the gel that fills the eyeball separates from the retina. It’s a common condition with age. PVD can cause floaters or flashes of light, which often fade over time. PVD isn’t painful or sight-threatening. But you should see an eye specialist right away to make sure you don’t have another retina problem.

What causes posterior vitreous detachment ( PVD ) in eye?

What causes posterior vitreous detachment (PVD)? The eyeball is filled with vitreous gel. This gel is made mostly of water and a protein called collagen. As you age, the gel becomes more liquid and the attachment of the back surface of the gel to the retina dissolves, leading to the gel separating from the retina.

Where is the firm vitreous attachment in the retina?

Other areas of firm vitreous attachment are at the edges of retinal scars, in areas of lattice and other vitreoretinal degenerations, at the optic disc, and along the major vascular arcades. Posterior vitreous detachment (PVD) occurs when the posterior vitreous separates from the retina and collapses anteriorly toward the vitreous base.

When to consider a vitrectomy for a PVD?

Vitrectomy can be considered with non-clearing vitreous hemorrhage. There are no medical therapies recommended for a PVD. After the diagnosis of an acute PVD, a follow up dilated fundus examination should be performed approximately 1 month afterwards.
