The presence of retinal tears with new onset of floaters was surprisingly high (14%; 95% confidence interval, 12–16%) as reported in a meta-analysis published as part of the Rational Clinical Examination Series in the Journal of the American Medical Association. [21]
Even after treatment, it can take months for the body to clear all of the blood from the vitreous. [2] In cases of vitreous hemorrhage due to detached retina, long-standing vitreous hemorrhage with a duration of more than 2–3 months, or cases associated with rubeosis iridis or glaucoma , a vitrectomy may be necessary to remove the standing ...
Rhegmatogenous retinal detachment is caused by a tear or break in the retina. [6] [9] This allows vitreous humor, the fluid that normally sits in the center of the eye, to build up behind the retina. [6] [9] As a result, the retina can eventually separate from the tissues underneath it. [6] [9] [10] This is the most common type of retinal ...

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.
An important differential diagnosis is Vogt–Koyanagi–Harada syndrome (VKH), which is thought to have the same pathogenesis, without a history of surgery or penetrating eye injury. Still experimental, skin tests with soluble extracts of human or bovine uveal tissue are said to elicit delayed hypersensitivity responses in these patients.
Proliferative vitreoretinopathy (PVR) is a disease that develops as a complication of rhegmatogenous retinal detachment.PVR occurs in about 8–10% of patients undergoing primary retinal detachment surgery and prevents the successful surgical repair of rhegmatogenous retinal detachment.
