Purpose: The purpose of this study was to determine the merits of a transconjunctival vitrectomy with the releasable suture technique in a large series of 20-gauge, 23-gauge, and hybrid trocar vitrectomy and to assess its effectiveness in minimizing the occurrence of incompetent wound closures.

Methods: One hundred and one patients, with a variety of vitreoretinal disorders, and totaling 125 eyes, were enrolled. Each entry site wound was closed, with the releasable suture technique using 8-0 nylon. Postoperatively, sutures were released under a slit lamp at the office a mean 22.9 hours after surgery. In addition to the usual intraoperative and postoperative identification of complications, preoperative and postoperative intraocular pressures were monitored.

Results: The full results from all 337 sclerotomies (206, 20 gauge; and 131, 23 gauge) were assessed. It was observed that there were no significant differences between preoperative and postoperative intraocular pressure measurements (P > 0.05); no eyes required fluid or gas supplements, there was no significant wound leakage or hypotony; and no significant complications occurred, such as endophthalmitis or choroidal detachment.

Conclusion: These results indicate that transconjunctival vitrectomy with releasable sutures, including those conducted with larger instrument trocar systems, offer patients excellent chances for a favorable outcome without incidences of postoperative wound leakage or hypotony.
