Retinal tears 180 degrees and greater. Management with vitrectomy and intravitreal gas.

A new technique for the treatment of giant retinal dialysis of 180 degrees or more has been devised. After the lens and vitreous have been removed via the pars plana, the patient is rotated into a prone position on a special operating table. The retina is unfolded by filling the eye completely with gas and is held in place by gas. The patient is then brought back into the normal supine position, and a scleral encircling procedure is added. The initial success rate of reattachment is 12 out of 14 cases. Afterward, many eyes develop massive periretinal proliferation. After six months or more of follow-up, the retina remained attached in six of 14 cases.
