What is posterior vitreous detachment?
Posterior vitreous detachment (PVD) occurs when the gel that fills the eyeball separates from the retina. It’s a natural, normal part of aging. PVD can cause floaters or flashes in your sight, which usually become less noticeable over time. The condition isn’t painful, and it doesn’t cause vision loss on its own.
How do you induce PVD?
In most cases, PVD can usually be induced by active aspiration of the vitreous cortex over the optic disc margin; however, this can be quite challenging in cases where the posterior hyaloid is firmly adherent to the optic disc edge and the retina.
Can I run with PVD?

How do you induce posterior vitreous detachment?

Can stress cause eye floaters?
If you frequently experience stress you might wonder, can stress cause eye floaters? The simple answer is, stress alone is not responsible for eye floaters appearing. Eye floaters are caused by deterioration of the vitreous humor which often happens as people age.

What are the risks of a vitrectomy for floaters?
During this procedure, nearly all the vitreous is removed, and with it, almost all of the vitreous opacities. Risks associated with vitrectomy include, but are not limited to, cataract formation, retinal tear and detachment, macular pucker, and macular edema (swelling). There is a small risk of vision loss.
How is CSF used to diagnose vitreous floaters?
A CSF assessment provides a functional evaluation of the impact of vitreous (as well as cornea or lens) opacification on vision, by measuring the ability to distinguish shades of gray, said Dr. Sebag. One of his studies found that patients with bothersome floaters had a 67% reduction in CSF compared with age-matched controls. 2
