Individuals with certain types of retinal tears or breaks may require treatments such as lasers or freezing (cryotherapy) to prevent detachment. [ 8 ] [ 10 ] Additionally, these patients are advised to avoid contact sports , eye trauma, and other high-risk activities, and to wear protective eyewear to reduce the risk of eye injury.
Treatment is largely aimed at reducing the amount of new blood vessel growth and preventing complications that may arise as a result, including retinal tears and detachments. Using a laser, an ophthalmologist burns the portions of the retina that are not supported by blood vessels, a technique known as laser photocoagulation. [1]
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.
A Snellen chart, which is frequently used for visual acuity testing Acute visual loss is a rapid loss of the ability to see . It is caused by many ocular conditions like retinal detachment , glaucoma , macular degeneration , and giant cell arteritis , etc.
During rhegmatogenous retinal detachment, fluid from the vitreous humor enters a retinal hole. The mechanisms by which retinal holes or tears form are not fully understood yet. The accumulation of fluid in the subretinal space and the tractional force of the vitreous on the retina result in rhegmatogenous retinal detachment.
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]
A tear in the retina can allow fluids from the eye to leak in behind the retina, which causes retinal detachment. When this occurs, blood from the retinal blood vessels can bleed into the vitreous. [4] Retinal tear accounts for 11.4–44% of vitreous hemorrhage cases. [1]
If the separation of the vitreous from the retina is not complete, areas of focal attachment or adhesions can occur, i.e. a VMA. The pulling forces or traction from this adhesion on the retinal surface can sometimes cause edema within the retina, damage to retinal blood vessels causing bleeding , or damage to the optic nerve causing disruption ...
