Abstract
Introduction: To investigate whether a previous history of vitrectomy affects sclerotomy self-sealing under gas tamponade in 23-gauge transconjunctival sutureless vitrectomy. Materials and Methods: This study retrospectively reviewed two groups, a vitrectomized group (seven consecutive cases) and an initial vitrectomy group (82 consecutive cases), who underwent 23-gauge transconjunctival sutureless vitrectomy at Jikei University School of Medicine Daisan Hospital in Tokyo. Factors affecting sclerotomy self-sealing were examined using multiple regression analysis. The criterion variable was massage time, and independent variables were age, surgical time, axial length, vitreous incarceration, history of vitrectomy, preoperative intraocular pressure (IOP), and postoperative IOP. Results: Age (F = 10.4) was the only significant factor. History of vitrectomy was not a significant factor (F = 0.06). Conclusions: Previous history of vitrectomy does not affect sclerotomy self-sealing under gas tamponade in 23-gauge transconjunctival sutureless vitrectomy.
