Scleral buckle versus pneumatic retinopexy for rhegmatogenous retinal detachments.

INTRODUCTION

Rhegmatogenous retinal detachment is caused by a tear in the retina and is a frequent cause of vision loss. Its treatment is mainly surgical and the following alternatives can be identified: scleral buckling or classic surgery, pneumatic retinopexy and vitrectomy. Between the first two options, most professionals prefer scleral buckling over pneumatic retinopexy, but the latter is a simpler, cheaper and lower-risk procedure, so it is still considered as an option for selected patients. However, there is little evidence comparing both interventions.

METHODS

To answer this question we used 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 three systematic reviews including six studies overall, of which three were randomized trials. We concluded the anatomic result might be better with scleral buckling in terms of retinal reattachment and risk of recurrence, but the risk of ocular adverse events might be lower with pneumatic retinopexy.
