The risk of retinal detachment is the greatest in the first 6 weeks following a vitreous detachment, but can occur over 3 months after the event.. The risk of retinal tears and detachment associated with vitreous detachment is higher in patients with myopic retinal degeneration, lattice degeneration, and a familial or personal history of previous retinal tears/detachment.
Peripheral (posterior) vitreous detachment occurs when the gel around the eye separates from the retina. This can naturally occur with age. However, if it occurs too rapidly, it can cause photopsia which manifests in flashes and floaters in the vision. Typically, the flashes and floaters go away in a few months.
As one gets older, pockets of fluid can develop in the vitreous. When these pockets develop near the back of the eye, the vitreous can pull away from the retina and possibly tear it. [2] Posterior vitreous detachment accounts for 3.7–11.7% of vitreous hemorrhage cases. [1]
Retinal detachment is typically painless, with symptoms often starting in the peripheral vision. [3] [9] [10] Symptoms of retinal detachment, as well as posterior vitreous detachment (which often, but not always, precedes it), may include: [3] [4] [9] [10] [12] Floaters suddenly appearing in the field of vision or a sudden increase in the ...
Weiss ring: a large, ring shaped floater that is sometimes seen if the vitreous body releases from the back of the eye. As part of the normal human aging process the liquefied vitreous body loses support and contracts. This leads to posterior vitreous detachment in which the vitreous membrane is released from the sensory retina. [9]
Vitreomacular traction syndrome (VTS) is a medical condition in the eye that is the result of tractional forces (pulling) being placed on the retina. [1] [2] VTS is common in people who have an incomplete posterior vitreous detachment, a type of retinal detachment at the periphery of the retina. [1]
Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes.Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
However, some patients may present with the symptoms of a posterior vitreous detachment or serous retinal detachment. This is because optic pits are associated with these disorders and are even speculated to be the actual cause of these disorders when they arise in patients with optic pits (see "Associated Retinal Changes" below for a more in ...
