An American research team has found that retinal detachment, a condition that puts an individual at risk for vision loss or blindness, can be treated with using one of three currently available surgical techniques.
"Although no randomized trials have been conducted that show definitively that one procedure is best for every situation, improvements in these surgical techniques have led to effective treatments for most patients," says Dr. Donald J. D'Amico, ophthalmologist-in-chief at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, professor and chairman of ophthalmology at Weill Cornell Medical College, and an international leader in vitreoretinal surgery.
Retinal detachment can occur when holes, tears or breaks appear in the light-sensitive retina as a result of trauma or pulling away of the gelatinous mass, known as the vitreous, that fills the back of the eye.
Though retinal tears occur most often in adults over age 60, they may occur much earlier, especially among people with high myopia.
The sudden onset of light flashes and "floaters" may signal an impending retinal detachment.
Dr. D'Amico has revealed that there are three surgical options that can be used to treat retinal detachment, namely scleral buckling, pneumatic retinopexy, and vitrectomy
In scleral buckling. a piece of silicone is sutured onto the outside wall of the eyeball and left in place permanently to create an indentation, or buckle, that restores contact with the detached retina. The individual tears are then closed by a localized scar that is induced with a freezing probe or laser.
