Autologous-Fibrin Induction: A Novel Approach for Sutureless Sclerotomy Closure in Pars Plana Vitrectomy.

AbstractPurposeMethodsResultsConclusionThis study presents a novel sutureless closure approach for sclerotomies following pars plana vitrectomy (PPV) and assesses its efficacy and safety.A total of 142 eyes were included in the study. PPV procedures were performed using 23-gauge (23 G) or 25-gauge (25 G) systems. Preoperative characteristics, intraoperative findings, and postoperative outcomes were documented.The cohort included 80 males and 62 females (mean age: 60.4 ± 12 years), primarily undergoing surgery for retinal detachment (59%). Among the patients, 87% underwent 25 G PPV (35% three-port, 52% four-port), while 13% underwent 23 G PPV (12% three-port, 1% four-port). Gas tamponade was administered in all cases, with perfluoropropane used in 45.7% of instances, sulfur hexafluoride in 29.5%, and air in 24.6%. Spontaneous closure was observed in 9.4% (47 of 501) of sclerotomies, autologous-fibrin induction approach successfully closed 75.8% (380 of 501) of the sclerotomies (83.7% of leaking sclerotomies) and 14.7% (74 of 501) of sclerotomies needed sutures. Visual acuity improved postoperatively, and first-day hypotony rate was 6.3%. Importantly, no serious complications such as choroidal detachment or endophthalmitis were observed during the postoperative period.The autologous-fibrin induction offers a simple, cost-efficient, and reliable approach for sutureless sclerotomy closure in PPV, with promising outcomes.
