Horowitz S, et al. - In this observational prospective study involving 327 patients (327 eyes), researchers assessed diathermy to minimize sclerotomy leakage during small-gauge vitrectomy and prevent ocular hypotony. The study sample consisted of patients who had diathermy to close the sclerotomy sites during 23-gauge pars plana vitrectomy (PPV). Glaucoma patients, topical/systemic steroids use exceeding 30 days, ocular inflammation, or trauma have been excluded. To assess potential risk factors, Chi-square, Kruskal–Wallis, Fisher Exact test, and multivariate statistical analyses were performed. The authors concluded that diathermy was secure and feasible to close sclerotomies. The most significant risk factors for persistent sclerotomy opening, which can be functionally closed without evidence of leakage or ocular hypotony, were vitreoretinal surgery reoperations and longer surgeries.
