Intraocular photocoagulation combined with transcleral cryotherapy under operation microscope for complicated retinal detachment

Objective To investigate the therapeutic efficacy of vitrectomy,intraocular photocoagulation combined with transcleral cryotherapy on retinal hole under operation microscope for complicated retinal detachment.Methods A total of 42 cases(42 eyes)with complicated retinal detachment were underwent vitrectomy,intraocular photocoagulation on slit pore combined with transcleral cryotherapy on retina under operation microscope.Visual acuity,intraocular pressure and complications were examined postoperatively.All patients were followed up for 6 months to 36 months,averaged in 25.3 months.Results About 36 cases(85.7%)were cured after the initial surgery,and achieved completely retinal reattachment.About 3 cases(7.1%)achieved complete retinal reattachment after the second surgery.About 39 cases(92.9%)were with retinal hole closed,complete retinal reattachment.Postoperative blind rate was 26.2% obviously lower than 81.0% at pre-operation(χ2=25.320,P0.001).There were 2 eyes(4.8%)with vitreous hemorrhage and 8 eyes(19.0%)with ocular hypertension postoperatively.Conclusion Vitrectomy,intraocular photocoagulation combined with transcleral cryotherapy on retinal hole under operation microscope for complicated retinal detachment is with favorable efficacy and important clinical application value.
