Application of perfluorocarbon liquids in vitrectomy

Objective To popularize the use of perfluorocarbon liquids in vitrectomy and increase the cure rate of complicated retinal detachment. Methods The clinical application of perfluorocarbon liquids during vitrectomy for complicated retinal detachment of 76 eyes has been summarized. The postoperative retinal detachment rate and visual acuity of 54 eyes with retinal detachment complicated with severe proliferative vitreoretinopathy and 11 eyes with giant retinal tears were analyzed statistically. Results The retina was reattached in 71 of 76 eyes (93.4%), in 50 of 54 eyes with severe PVR (92.6%) and in 9 of 11 eyes with giant retinal tears (81.8%). The postoperative visual acuity was above 0.02 in 69 eyes (90.8%) and >0.1 in 29 eyes (38.2%) of 76 eyes, respectively in 50 (92.6%) and 18 (33.3%) of 54 eyes with severe PVR and 9 (81.8%) and 4 (36.4%) of 11 eyes with giant retinal tears. During surgery, perfluorocarbon entered through tears into subretinal space and was removed immediately in 6 of 76 eyes. Postoperatively, a small portion of residual perfluorocarbon liquid was observed in the anterior chamber of 17 of 76 eyes and in the vitreous cavity of 2 phakic eyes of 76 eyes, no complication was observed except one case with mild corneal opacification. Conclusion Perfluorocarbon liquids are the useful adjunct to the hydrokinetic manipulation in vitreous surgery.
