Common causes of failure in retinal detachment repair include missed or poorly sealed retinal breaks, new retinal breaks, and proliferative vitreoretinopathy (PVR). [ 10 ] [ 14 ] PVR, a condition where scar tissue grows on the retina, occurs in approximately 8–10% of patients undergoing treatment for retinal detachment.
A scleral buckle is one of several ophthalmologic procedures that can be used to repair a retinal detachment. Retinal detachments are usually caused by retinal tears, and a scleral buckle can be used to close the retinal break, both for acute and chronic retinal detachments. [citation needed] Scleral buckles come in many shapes and sizes.
Laser photocoagulation, or photocoagulation therapy, is the use of a laser to seal a retinal tear. [21] Pneumatic retinopexy; Retinal cryopexy, or retinal cryotherapy, is a procedure that uses intense cold to induce a chorioretinal scar and to destroy retinal or choroidal tissue. [24] Macular hole repair; Partial lamellar sclerouvectomy [25]
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.
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.
Laser photocoagulation can help prevent the deterioration of some retinal disorders and reduce the risk of future vision loss, but it cannot restore vision once it has been lost. The procedure is safe and effective for treating indicated retinal disorders, such as tears and glaucoma. It is typically an outpatient procedure lasting 15 to 20 minutes.
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] By doing so, this tissue will no longer release molecules that stimulate blood vessel growth. If a retinal detachment occurs, laser therapy or surgery may be required to repair the retina ...
Retinal tufts increase the risk of a retinal tear or a detached retina, although the risk is not high- 1% of tufts are thought to lead to retinal detachment. [2] [6] In addition if there is retinal thinning near a zonular traction tuft, there is an increased risk of retinal detachment. [5]
