Living with Posterior Vitreous Detachment. Neither cataract surgery nor PVD (posterior vitreous detachment) have any adverse effect on retinoschisis (neither will cause it to progress - pathology is within the retina and not at the vitreoretinal interface.) A posterior vitreous detachment in itself is normal. A Posterior Vitreous detachment can usually be detected diring a dilated retinal exam. Spontaneous posterior vitreous detachment (PVD) is a common age-related condition in patients aged ≥45 years.

The vitreous is attached to the retina by millions of microscopic fibers. Posterior vitreous detachment (PVD) is a common condition among patients of 45 years or older (Dayan et al. 1. But it can sometimes signal . The peripheral vitreous gel then collapses into the central, liquefied vitreous, detaching from the retina (like Jell-O separating from the inside of a gelatin mold or bowl). As one ages, the vitreous undergoes "syneresis," in which it becomes more fluid or liquid-like. Neudorfer M, Fuhrer AE, Zur D, Barak A Indian J Ophthalmol 2018 Dec;66(12):1802-1807. doi: 10.4103/ijo.IJO_373_18. The retina is a light-sensitive area at the back of the eye.

My experience and feelings with PVD. OCT provides a detailed, high magnified, cross-section . PVD occurs when the vitreous gel that fills the eye separates from the retina—the light-sensing nerve layer at the back of the eye—and is associated with seeing flashes of light or "floaters" in your peripheral vision. Vitreous degeneration, which is sometimes also known as a posterior vitreous detachment or PVD, is an eye problem that happens when the vitreous membrane on the surface of the eyeball detaches from the retina temporarily.

Early in life the vitreous gel (analogous to the yolk of an egg) fills the entire inner cavity of the eye (like the yolk fills the eggshell). As the vitreous begins to collapse and tear away from the retina, sometimes this attachment is so strong that a tear or break can occur in the sensory retinal tissue as the vitreous separates from it. The membrane has attachments at specific sights in the back of the eye, but also can have random unknown . I think as you have been checked and there is no tear you will be ok.

OCT is a non-invasive, quick photograph that uses light rays to measure the thickness of the retina. A posterior vitreous detachment (PVD) is defined as the separation of the posterior hyaloid face from the neurosensory retina. It's responsible for detecting light and turning it into visual images. The lower rate of posterior vitreous detachment induction at 25 U/ml was associated with a weakening of the attachment of retinal pigment epithelium to Bruch's membrane by the higher concentration of dispase since the retinal pigment epithelium, sensory retina and vitreous left the eye cup as an intact unit when the eye cup was tilted. A posterior vitreous detachment occurs when the vitreous gel separates from the retina, which lines the back wall of the eye. Distinguishing between retinal detachment and posterior vitreous detachment should be done with an abundance of caution since accuracy is not perfect and these pathologies can occur simultaneously.

Posterior Vitreous Detachment. Eye floaters resulting from a posterior vitreous detachment are then concentrated in the more liquid vitreous found in the interior center of the eye. PVD may produce retinal breaks in areas of firm vitreoretinal attachments and on narrow posterior extensions . Retinal detachment, defined as the presence of subretinal fluid extending beyond 1 disk diameter of the edge of the tear, is estimated to occur in 3% to 7% of eyes with symptomatic PVD.
