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.
The ultimate release of the vitreous around the optic nerve head sometimes makes a large floater appear, usually in the shape of a ring ("Weiss ring"). [15] Posterior vitreous detachment is more common in people who: are nearsighted; have undergone cataract surgery or clear lens extraction; have had Nd:YAG laser surgery of the eye;
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 ...
Vitreous shrinkage or liquefaction, which is the most common cause of photopsia, causes a pull in vitreoretinal attachments, irritating the retina and causing it to discharge electrical impulses. These impulses are interpreted by the brain as flashes.
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]
Vitreous hemorrhage can be caused by proliferative diabetic retinopathy, vitreous detachment with or without retinal breaks, and trauma. Less common causes include vascular occlusive disease , retinal arterial macroaneurysm , hemoglobinopathy , age-related macular degeneration , and intraocular tumors .
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).
