To avoid postoperative "compartmentalization" of the vitreous cavity, which can potentially accelerate the recurrence of proliferative vitreoretinopathy (PVR), 32 eyes of 32 selected patients with complicated retinal detachment were managed with lensectomy, vitrectomy, 5-day internal tamponade with perfluorocarbon liquids (PFCL) and postoperative supine positioning until PFCL removal. Intraoperatively, 19 eyes had grade C3 or greater PVR; 10 eyes exhibited ocular trauma and 6 displayed giant tears. All but 5 patients (PFCL/fluid exchange) underwent PFCL/silicone oil exchange 5 days after surgery. Anatomic attachment of the retina was achieved with one operation in 25 (78%) of the 32 eyes with a median follow-up of 8 months (mean 8.4 months). Of the 20 eyes that underwent silicone oil removal, none redetached. Nineteen eyes (61%) showed no or only mild reproliferation; a macular pucker developed in 50% of the 20 eyes successfully reattached after PFCL/silicone oil exchange and in none of the 5 eyes successfully reattached after PFCL/fluid exchange. Intraocular tolerance of PFCL for up to 5 days of internal tamponade appeared to be good as judged by static threshold perimetry in the two patients tested and by our functional outcomes, with 88% of the reattached eyes showing a final visual acuity of 5/200 or better.
