Abstract
Objective To explore the operative effectiveness of scleral cryotherapy combined with intraocular laser photocoagulation under operation microscope on retinal detachments with giant retinal tear.MethodsNineteen cases(19 eyes)of retinal detachments with giant retinal tear were enrolled in this study.All cases underwent pars planar vitrectomy,intraocular laser photocoagulation combined with scleral cryotherapy and temporary silicone oil tamponade under operation microscope.The effect on the reattachment rate and visual acuity were evaluated postoperatively.ResultsMean postoperative follow-up time was 21.3 months(ranging from 6 months to 36 months),15 cases(78.9%)achieved retinal reattachment after the initial surgery;owing to postoperative proliferative vitreoretinopathy caused retinal holes unclosed,4 cases(21.1%)were redetached under silicone oil tamponade postoperative from 2 weeks to 5 months.Among 11 eyes removed silicone oil,recurrent retinal detachment occurred in 1 eye.Postoperative acute vision improved in 15 cases,unchanged in 3 cases and decreased in 1 case.As compared with preoperative blindness rate(78.9%),the postoperative blindness rate(26.3%)was significantly decreased(χ2=10.526 3,P0.05).Postoperative cataract occurred in 6 phakic eyes,high intraocular pressure in 5 eyes,subretinal hemorrhage in 3 eyes,vitreous hemorrhage in 2 eyes and band degeneration of cornea in 1 eye.ConclusionsThe intraocular laser photocoagulation combined with scleral cryotherapy and temporary silicone oil tamponade under operation microscope can achieve favorable anatomical and visual results in the treatment of retinal detachments with giant retinal tear.
