Safety and efficacy of ultrasound-guided pars plana vitrectomy: a prospective, single-arm study.

ABSTRACT: To estimate the amount of eliminated vitreous after ultrasound-guided pars plana vitrectomy and complete the safety profile of the technique. We enrolled patients with vitreous hemorrhage and clear media who had an ultrasound-guided pars plana vitrectomy. The amount of eliminated vitreous was calculated by digital analysis (ImageJ) of before and after photos, obtained intraoperatively. All cases were completed under direct visualization for safety evaluation. All patients had a comprehensive ophthalmological examination at baseline and at day 1, and 1 month follow-up. Adverse events were reported in proportions ± 95%CI. A learning curve was plotted via the formula y = ax^b. Interobserver agreement was assessed with a Cohen-Kappa test. We enrolled 62 patients. Mean age: 64.3 ± 13.3 years. D
