Local dry vitrectomy combined with segmental scleral buckling and viscoelastic tamponade for rhegmatogenous retinal detachment with vitreous traction

摘要

AIM:To demonstrate local dry vitrectomy combined with segmental scleral buckling and viscoelastic tamponade for the treatment of partial rhegmatogenous retinal detachment(RRD)with local vitreous traction in patients at high-risk for proliferative vitreoretinopathy(PVR).METHODS:Eleven eyes of 11 patients were retrospectively studied,including 5 retinal dialysis and 6 retinal detachment(RD;5 eyes with peripheral retinal hole and I eye with giant tear).All patients exhibited partial RD and local vitreous traction.Combined local dry vitrectomy without conventional infusion and segmental scleral buckling was performed.Viscoelastic fluid was injected into the vitreous cavity if needed Demographic information,preoperative and post­operative complications,and outcomes were recorded.RESULTS:The mean age of the patients at presentation was 26.55±13.52y.All 11 patients obtained retinal reattachment after a single surgical intervention.Postoperative visual acuities were improved or remained stable in all patients.None of them developed complications,except for temporary mildly increased intraocular pressure in 3 cases.CONCLUSION:Combined local dry vitrectomy and segmental scleral buckling are effective for patients of RRD with local vitreous traction.The technique avoids many complications associated with regular surgery and was minimally invasive to both the external and internal eye.
