Abstract
Fifty patients with retinal detachment accompanied by vitreous haemorrhage, perforating eye injuries, intraocular foreign bodies, massive preretinal retraction,.giant tears greater than 180 degrees, and proliferative retinopathies underwent pars plana vitrectomy, cryocoagulation, scleral buckling, and intravitreal gas injection. Intraoperative complications included minimal to moderate bleeding and iatrogenic retinal tears, but no retinal dialysis was produced at the pars plana sclerotomy site. Postoperative complications included recurrent vitreous haemorrhage, rubeosis, haemolytic, erythroclastic, or neovascular glaucoma, transient increase of intraocular pressure, uveitis, and macular pucker. Phthisis bulbi occurred in 6 eyes; in 3 of these eyes enucleation was required. Successful reattachment was accomplished in 56% of these complicated retinal detachments, most of which had been considered inoperable by conventional techniques. Visual improvement was achieved in 46% of eyes. Follow-up ranged from 6 to 29 months.
