Intraocular argon laser photocoagulation in the management of severe proliferative vitreoretinopathy.

We surgically repaired seven eyes with severe proliferative vitreoretinopathy with intraocular argon laser photocoagulation. Five of the seven retinas were still attached six or more months postoperatively. Endolaser photocoagulation was used in conjunction with pars plana vitrectomy, periretinal membrane stripping, fluid-air exchange, and planned retinotomies. The advantages of endolaser photocoagulation include easier management of posterior retinotomies in an air-filled eye, isolation of anterior traction and retinal breaks by creating an encircling demarcation line posterior to the problem, and less manipulation of existing scleral buckling material.
