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.
A scleral buckle is used in the repair of a retinal detachment to indent or "buckle" the sclera inward, usually by sewing a piece of preserved sclera or silicone rubber to its surface. [23] Laser photocoagulation, or photocoagulation therapy, is the use of a laser to seal a retinal tear. [21] Pneumatic retinopexy
Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4] Retinal detachment is a medical emergency that requires surgery. [2] [3]
Photocoagulation – In cases when there is a tear in the retina, or when there are unhealthy damaging blood vessels (which can be seen in patients with diabetic retinopathy), laser treatment can be used. [7] In such cases, the laser is used to seal the hole or prevent growth of the unhealthy, damaging blood vessels.
The first successful use of photodisruption was in 1972, on a case of trabecular meshwork. [1] Photodisruption came to wide use in the early 1980s for the treatment of extracapsular cataract extraction. [1] The technique is most commonly used for lithotripsy of urinary calculi and the treatment of posterior capsulotomy of the lens. [3]
Barrage laser is at times done prophylactically around a hole or tear associated with lattice degeneration in an eye at risk of developing a retinal detachment. It is not known if surgical interventions such as laser photocoagulation or cryotherapy are effective in preventing retinal detachment in patients with lattice degeneration or ...
Laser surgery is a treatment option which uses a laser beam to seal off damaged blood vessels in the retina. [9] Anti-vascular endothelial growth factor (VEGF) drugs like Avastin and Lucentis have also been shown to repair retinal hemorrhaging in diabetic patients and patients with hemorrhages associated with new vessel growth. [10] [11]
In order to see a clear image, the eye must focus rays of light on to the light-sensing part of the eye – the retina, which is located in the back of the eye.This focusing – called refraction – is performed mainly by the cornea and the lens, which are located at the front of the eye, the anterior segment.
