Purpose: Outcomes of pneumatic retinopexy (PnR) using surgical microscope, wide-angle viewing system, and chandelier endoilluminator (microscope-assisted pneumatic retinopexy) for primary rhegmatogenous retinal detachment (RRD)., Methods: Retrospective study. 43 consecutive eyes with RRD undergoing microscope-assisted PnR surgery (MAPR) were analysed. Inclusion criteria comprehend phakic eyes with single retinal break or a group of breaks in detached retina in the same quadrant above 8- and 4-o'clock meridians. Follow-up was at least 6 months., Results: Of the 43 eyes, a total of 25 (58%) presented preoperatively a single retinal break, 15 (35%) had two retinal breaks in the same quadrant and 3 (7%) presented three or more retinal breaks in the same quadrant. Other retinal breaks not observed preoperatively were discovered intraoperatively in 12 eyes (28%). In 9 (21%) the missed retinal breaks were in the same quadrant as the main diagnosed break(s), while 3 (7%) had missed retinal breaks in a different one. These 3 eyes as no longer adhering to the PnR indication criteria switched intraoperatively to other surgical procedures and were excluded in the reattachment rate results. The total primary reattachment rate with MAPR was achieved in 37 eyes (92.5%). No significant BCVA changes were observed postoperatively., Conclusion: MAPR is an effective and safe surgical option, it allows to work with both hands free and provides an adequate visualization of the retina during the procedure minimizing the risk of missed retinal breaks potentially leading to surgical failure.
