INTRODUCTION Cataract surgery increases the risk for rhegmatogenous retinal detachment. Pars plana vitrectomy and scleral buckling are two surgical procedures used for its repair. The combination of both techniques had been proposed for rhegmatogenous retinal detachment in patients with previous cataract surgery (pseudophakic or aphakic), but its effectiveness remains unclear. METHODS We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS We identified four systematic reviews with eight studies overall, one of them was a randomized trial. With this data, we conclud-ed that pars plana vitrectomy plus scleral buckle may make little or no difference in primary or final retinal reattachment rate nor in final visual acuity, but the certainty of the evidence is low. In terms of surgery complications, we are uncertain if vitrecto-my plus scleral buckle increases the risk of proliferative vitreoretinopathy or reduces the risk of glaucoma because the certainty of the evidence is very low.

Introduction: Cataract surgery increases the risk for rhegmatogenous retinal detachment. Pars plana vitrectomy and scleral buckling are two surgical procedures used for its repair. The combination of both techniques had been proposed for rhegmatogenous retinal detachment in patients with previous cataract surgery (pseudophakic or aphakic), but its effectiveness remains unclear., Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach., Results and Conclusions: We identified four systematic reviews with eight studies overall, one of them was a randomized trial.

Background: A giant retinal tear is defined as a full thickness break in the neurosensory retina that extends circumferentially for 3 or more clock hours around the retina in the presence of a posterior vitreous detachment. It is one of the more complex surgical scenarios that a retina surgeon can face. There is no consensus on the ideal surgical technique; however, the "traditional" approach has been to perform a combined procedure including lensectomy, scleral buckle and vitrectomy., Objective: To report the outcome over 2 years of five patients with giant retinal tears managed with lens sparing, bimanual 23-gauge vitrectomy without scleral buckle., Methods: Retrospective analysis of patients with giant retinal tears managed with lens sparing, bimanual 23-gauge vitrectomy without scleral buckle. Included in the analysis were age, lens status, etiology and size of the tear, pre- and postoperative visual acuity, anatomic success, tamponade used, laser or criopexy where recorded., Results: Three patients had high myopia, one secondary to blunt trauma and one with Wagner-Stickler syndrome were included in the analysis. The size of the tear varied from 120-280°. Anatomic success was achieved in all patients. One patient developed proliferative vitreoretinopathy and was re-operated and the retina remained attached., Conclusions: In this group of selected patients, lens-sparing bimanual 23-gauge vitrectomy without scleral buckle seems a safe and effective option in the management of retinal detachment associated with giant retinal tears. Further prospective and comparative studies are warranted to establish the role of this technique in the treatment of patients with this complex pathology.
