Objective:
To investigate the effects of needle infusion on preventing wound leakage and hypotony in sutureless vitrectomy.
Methods:
We retrospectively reviewed 230 consecutive eyes of 23-gauge pars plana vitrectomy with or without needle infusion, and further measured the wound leakage and intraocular pressure (IOP) without using a suture.
Results:
In the eyes with primary needle infusion inserted before infusion cannula removal, IOP was stable during and after infusion cannula removal. No suture was needed in the procedure. Postoperative hypotony did not occurred in all eyes with needle infusion either.
Conclusion:
Needle infusion inserted before infusion cannula removal can avoid using sutures and prevent hypotony intraoperatively and postoperatively.
