Use of perflurocarbon liquids in vitrectomy for complicated vitroretinopathy

Objective:To investigate the role of perflurocarbon liquids (PFCLs) in vitrectomy for complicated vitroretinopathy.Methods:Eighteen cases (18 eyes) of complicated proliferative vitroretinopathy were treated by vitrectomy.A small quantity of PFCLs was used during and after retinal membrane peeling,retinal funnels opening and posterior retina stabilization.Edolaser photocoagulation was performed and C3F8 or silicon oil was filled.Visual acuity and retinal reattachment condition were examined after the operation.Results:The rate of retinal reattachment reached 77.8%.The final visual acuity of 10 cases reached 0.05 or above.The effect was obvious (P<0.01).A small amount of PFLCs retained in 2 cases (11.1%) and secondary glaucoma occurred in 1 case.Conclusions:As a hydrodynamic operative tool,PFCLs can be used in vitrectomy for complicated vitroretinopathy to facilitate the operation and improve the outcome.
