          Abstract

          We report a case with multiple recurrences of retinal detachment (RD) with severe proliferative vitreoretinopathy in a 12-year-old child who underwent vitrectomy using a heavy liquid perfluoro-n-octane (PFO) as a short-term postoperative tamponade. He had an encircling band and three vitrectomies with gas, followed by silicone oil tamponade for retinal redetachment prior to the use of PFO as a short-term tamponade. Short-term PFO tamponade was used in which inferior retinal reattachment was considered to be difficult with conventional gas or silicone oil tamponade, especially in regard to proper postoperative posturing. The PFO was left in the eye for 1 week, and the retina remained reattached after removal of the PFO which was replaced with silicone oil tamponade in this case. PFO appears feasible and tolerable as a short-term postoperative tamponade in the management of complex pediatric RD.

          Low viscosity liquid fluorochemicals in vitreous surgery.

           S. Chang (1987)
          Low viscosity liquid fluorocarbons have physical properties potentially useful as intraoperative adjuncts during vitreous surgery for complicated retinal detachments. These substances are optically clear, have specific gravity greater than that of water, and interfacila tension properties similar to those of silicone oil. In four patients who had complicated retinal detachments I used perfluorotributylamine and perfluorodecalin during vitreous surgery. Two giant retinal tears were flattened intraoperatively without turning the patient into the prone position. In two patients with severe proliferative vitreoretinopathy, perfluorotributylamine allowed adequate retinal tamponade and avoided a posterior retinotomy for internal drainage of subretinal fluid. Endophotocoagulation was applied.

            Intraoperative perfluorocarbon liquids in the management of proliferative vitreoretinopathy.

            Three low-viscosity perfluorocarbon liquids were used intraoperatively for hydrokinetic manipulation of the retina during vitreous surgery for retinal detachment with advanced proliferative vitreoretinopathy. All 23 patients had massive proliferative vitreoretinopathy (Grade D, Retina Society classification), and 16 (69.6%) had Grade D-3 with a closed-funnel configuration. In 21 eyes the retina could be flattened intraoperatively by perfluorocarbon liquids without requiring posterior retinotomy for internal drainage of subretinal fluid. The temporary mechanical fixation of the retina provided by this tool facilitated the removal of epiretinal membranes and release of traction. Fifteen eyes (65.2%) maintained long-term retinal reattachment with follow-up of six months or more. These liquids are useful adjuncts in the management of retinal detachment with severe proliferative vitreoretinopathy.

              Outcomes and complications associated with giant retinal tear management using perfluoro-n-octane.

              To report visual acuity and anatomic outcomes, as well as complications, associated with giant retinal tear management using intraoperative perfluoro-n-octane and to investigate clinical features associated with anatomic and visual acuity outcomes. A prospective, noncomparative, observational, multicenter study. Two hundred twelve patients (212 eyes) > or =15 months of age who underwent giant retinal tear management with intraoperative perfluoro-n-octane at 24 study sites between April 1994 and February 1996. Giant retinal tear was defined as a retinal tear extending > or =90 degrees. Vitrectomy with perfluoro-n-octane intraoperative retinal tamponade. Visual acuity and rates of retinal reattachment, reoperation, retained perfluoro-n-octane, corneal edema, elevated intraocular pressure (IOP > 25 mmHg), hypotony (IOP or =20/200 was measured in 56 (27%) patients preoperatively and 67 (47%) patients at 6 months. Postoperative visual acuity improved in 107 (59%) eyes, remained stable in 44 (24%) eyes, and worsened in 29 (16%) eyes (percentages are based on the number of patients for whom the data were available at these time points). Of the 124 patients with visual acuity or =20/200 include male gender, no prior vitrectomy, better preoperative vision, and no need for relaxing retinotomy. After adjusting for recurrent detachment, factors significantly associated with vision > or =20/200 include no prior vitrectomy, better preoperative vision, and no need for relaxing retinotomy. Retinal reattachment and preserved visual acuity were achieved in most eyes that underwent giant retinal tear management with intraoperative perfluoro-n-octane. Significant risk factors for recurrent retinal detachment include size of retinal tear, age, prior vitrectomy, and female gender. After adjusting for recurrent detachment, significant predictors of postoperative vision >or =20/200 include no prior vitrectomy, better preoperative vision, and no need for relaxing retinotomy.
