BACKGROUND AND OBJECTIVE: Most surgeons now utilize small-gauge (23- or 25-gauge) pars plana vitrectomy (PPV) with or without scleral buckling for repair of rhegmatogenous retinal detachments (RRD), in addition to primary scleral buckle (SB), but comparative data between the two gauges are limited. PATIENTS AND METHODS: This study is an analysis of primary RRD repairs comparing 23- versus 25-gauge vitrectomy for PPV or combination PPV/SB from January 1, 2015, through December 31, 2015, across multiple institutions. The primary outcome was single-surgery success and secondary outcomes included postoperative complications. RESULTS: There were 1,932 eyes that met inclusion criteria. There was no statistically significant difference in single-surgery success (82.9% vs. 83.8%; P = 0.6329). There were similar rates of postoperative hypotony, endophthalmitis, vitreous hemorrhage, and choroidal detachment. The findings were similar when analyzing only eyes that underwent primary PPV without SB. CONCLUSION: Both 23- and 25-gauge vitrectomy systems have similar anatomic and visual outcomes in the primary repair of RRD. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:70–76.]
Introduction Machemer et al. derived the first single-port pars plana vitrectomy (PPV) in 1971 using a closed 17-gauge vitreous cutter. (1) Since that time, PPV has continuously advanced to smaller [...]
