Abstract
Purpose :
Over the last two decades microincision small gauge vitrectomy surgery has become widespread. Many small gauge cases still warrant suturing of sclerotomies. We describe the use of four-loop single throw suture for the closure of conjunctival peritomies and some sclerotomies.
Methods :
A retrospective review of sutured 23- and 25-gauge pars plana vitrectomy cases where all the overlying focal peritomies were closed using a four-loop single throw 7-0 and 8-0 vicryl suture. Main outcome measures on postoperative follow ups included maintenance of closure, and position of the knot ends.
Results :
The retrospective review included 23 cases with 69 peritomy closures and 6 sclerotomy closures using the four-loop single throw technique. The wounds remained closed with no unraveling of the suture at day 1, week 1, and month 1. The ends of the knot stayed flat against the ocular surface with no obvious significant suture related discomfort. No suture granulomas or hypotony was noted in 6 scleral closures with this technique over a 1 month follow up.
Conclusions :
The described technique is an effective way of closing conjunctival peritomies and some sclerotomies using minimal suture material which reduces the operative time, and may minimize suture related discomfort.
