Purpose: To characterize the healing of the sutureless sclerotomies of the transconjunctival 25 gauge pars plana vitrectomy system (TSV25) with ultrasound biomicroscopy (UBM) compared to traditional sutured 20-gauge pars plana vitrectomy (PPV). Methods: UBM was used to evaluate the sclerotomies of patients undergoing vitrectomy with the TSV25 system and traditional PPV. Scans were obtained on post-operative day 1, week 1, and month 1. Results: UBM evaluation of the TSV25 vitrectomies showed open sclerotomies with intact overlying conjunctiva on day 1. By week 1, the sclerotomies had closed with vitreous incarceration visible in the majority of sclerotomies evaluated. Month 1 UBM evaluation did not appreciably differ from week 1 scans. The UBM characteristics of traditional 20-gauge PPV sclerotomies did not differ from those of the TSV25 sclerotomies by week 1. Conclusions: Sclerotomies made with the TSV25 system follow a predictable wound healing pattern with vitreous incarceration. The UBM evaluations of the TSV25 sclerotomies appear similar to traditional sutured 20-gauge PPV sclerotomies.
