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
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
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
Ciliary body: The aqueous functions as the clear "blood" of the front of the eye. It is produced in a ring gland behind the outer edge of the iris called the ciliary body. The fluid bathes the eye interior and supplies oxygen and nutrients to the lens and the inside of the cornea, carrying away waste products and carbon dioxide. Dysfunction of the drains can lead to glaucoma. ...Read more
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
Yes: Most common procedure to repair a retinal detachment resulting from a macular hole is a vitrectomy (remove the fluids from the back of the eyeball), replace it with a gas, and position the patient face down for some period of time (sometimes weeks) to allow the hole to close and the detachment to resolve. Most macular holes do not cause a detached retina, but many require a similar operation. ...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
Many possible causes: As we age, the vitreous may pull away from its attachment to the retina at the back of the eye. If the vitreous pulls hard enough to tear the retina in one or more places, fluid may pass through, lifting the retina off the back of the eye, causing it to detach. Some risk factors for detachment are: nearsightedness, trauma to the eye or a family history of retinal detachment. ...Read more
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
Does vitreous degeneration always lead to a posterior vitreous detachment (pvd) or pvd may not happen altogether in presence of vitreous degeneration?
Older Adults Common: Retinal detachment is typically a disorder associated with older adults, usually over 50. It can occur in younger folks due to trauma or genetic conditions. The best way to be sure is to be seen by an ophthalmologist and get a dilated exam of the retina. Common symptoms of retinal detachment are flashing lights and floaters, a dark curtain, and vision loss. Rd is a potentially blinding condition. ...Read moreSee 3 more doctor answers
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
