Posterior Vitreous Detachment And Exercise
Wouldnt pars plana vitrectomy reduce the risk of retinal tears or detachments due to vitreoretinal traction for someone with lattice and vitr degen?
The vitreous jelly is normally attached to the back of the eye (posteriorly), to the optic nerve and macula (central retina). When this collagenous jelly separates from these normal attachment areas, it's called a posterior vitreous detachment (pvd). This happens with age (normal and most common reason), trauma, eye surgery, nearsightedness. A retinal tear or detachment ...Read more
If prior retinal tear, risk at 60 of developing a retinal detachment or a posterior vitreous detachment?
See a retina special: You do have a somewhat increased risk of developing a retinal detachment if you've had a retinal tear (even if it was treated), though you should speak to your retina specialist to gauge your true risk based on your exam. Everyone develops posterior vitreous detachments as we age - that is regardless of having had a tear or not. ...Read moreSee 1 more doctor answer
During posterior vitreous detachment, the vitreous separates from the macula first or peripheral retina or no preference?
Generally peripheral: Vitreous degeneration, the conversion of the vitreous gel into a dense syrup, usually starts peripherally and eventually involves the center including the macula. In most cases it is a benign and normal event but if adhesions exist, then the retinal can lift up and tear or become detached. ...Read more
Does doing a laser retinopexy around areas of lattice degeneration reduce the risk of tractional tears ensuing from posterior vitreous detachment?
Yes,it should reduce: Yes, the decision for retinopexy is best made by retina subspecialist who can assess whether the degree of lattice ; or the presence of high risk thinning would warrant the risks. Retinopexy creates a tighter bonding so that in event of PVD there is lower likelihood of retinal tears. ...Read more
See below: A posterior vitreous detachment is a condition of the eye in which the vitreous humour separates from the retina. Broadly speaking, the condition is common for older adults and over 75% of those over the age of 65 develop it. Although less common among people in their 40s or 50s, the condition is not rare for those individuals. Some research has found that the condition is more common among women. ...Read moreSee 1 more doctor answer
Why do post-cataract surgery retinal detachments occur? Is there some retinal pulling involved from posterior vitreous detachment (pvd)?
Destabilization: The natural lens and its supports stabilize the front of the eye and vitreous. Removal of the thick natural lens and substitution with a thin artificial lens, increases the chance for the vitreous to move in ways that can destabilize the attachments of the vitreous over the retina. If there are weak places, this can increase the chance of detachment, even in the best of cataract surgeries. ...Read moreSee 1 more doctor answer
Does vitreous degeneration always lead to a posterior vitreous detachment (pvd) or pvd may not happen altogether in presence of vitreous degeneration?
Can anterior vitreous detachment occur before pvd? Does it reduce the retinal risks assoc with cataract surgery? Symptoms other than floaters?
Vitreous detachment: May occur at the level of the anterior retina adjacent to an area called the ora serrata. The vitreous may delaminate from the retina at any location, meaning either posterior or anterior at anytime either from trauma or idiopathic. If the vitreous is already detached from the retina, then the risks of a retinal detachment is theoretically reduced. ...Read moreSee 1 more doctor answer
Opth diagnosis of few vitreous floaters ou & no posterior vitreous detach noted ou. What is the difference between floaters and pvd? Same prognosis?
Floaters and pvd: Floaters are "things" in the vitreous cavity that you can see floating in your vision. The "things" can be blood, inflammatory cells, parasites, or most commonly, clumps of the normal vitreous material. A posterior vitreous detachment is when the back of the vitreous becomes separated from the retina. A PVD is usually accompanied by floaters. ...Read moreSee 2 more doctor answers
See a retina special: As we age, the vitreous jelly pulls away from the retina (a posterior vitreous detachment). New or worse floaters in your vision or flashing lights or loss of peripheral vision (like a curtain or veil obstructing the vision) could indicate a retinal detachment. These symptoms require an urgent dilated retinal exam. Do not delay. ...Read moreSee 1 more doctor answer
Yes: The vitreous jelly that fills the eye and attaches to the back wall of the inside of the eye (the retina) will detach from the retina with age (posterior vitreous detachment). At that time or days/weeks later a retinal tear or detachment may or may not occur as well. The latter conditions require urgent treatment before blindness ensues. A vitreous detachment is not treated. ...Read moreSee 2 more doctor answers
What are the chances of pvd leading to a retinal tear or detachment in young high myopia(30-40)age group?Can flashes of eyes persist 4ever after pvd?
Higher: The risk is probably 10 x greater than a patient without these characteristics. Still probably about 1/1000 unless you have a family history of retinal tear and detachment. ...Read more
Normal process: The vitreous is a gel that fills the back of the eye, holding everything in place (it is why boxers can do what they do). Starting in middle age, the vitreous changes to a dense fluid and detaches from its normal position. This sometimes causes floaters and light flashes, Usually it is benign, but it is universal and can be detected by an ophthalmologist as a P.V.D. ...Read more
Age: The vitreous jelly changes as we age and it pulls away from the back of the eye (retina) - a posterior vitreous detachment. During this process, if the jelly pulls hard enough on the retina (especially in a thin or weak area) it can tear the retina which can subsequently detach. Other risk factors include myopia, cataract surgery, head/eye trauma, family history, lattice degeneration, etc. ...Read more
Any one older: Vitreous detachment is universal in older age and represents the transition of the gel vitreous into a dense syrupy liquid. It usually happens silently but when symptoms occur (floaters, light flashes, visual changes) these mimic those of retinal detachment which is serious. If you have these symptoms, see your ophthalmologist for evaluation to distinguish these two. ...Read more
If posterior vitreous detachment happen in yung high myopic like me without retinal tear, is der a chance of future retinal tear due 2 cataract/glucoma?
Higher: The risk is probably 10 x greater than a patient without these characteristics. Risk ia about 1/1000 unless you have a family history. Having glaucoma and a cataract do not increase this risk. Having cataract surgery does increase the risk of retinal tears. You should talk your eye md. ...Read moreSee 1 more doctor answer
