To evaluate the outcome of 25-gauge transconjunctival pars plana vitrectomy and compare it with that of 20-gauge pars plana vitrectomy for primary repair of rhegmatogenous retinal detachment.
A retrospective study of a consecutive series of 166 eyes of 164 patients who underwent pars plana vitrectomy for primary rhegmatogenous retinal detachment was performed. One hundred nineteen eyes underwent 25-gauge vitrectomy and 47 eyes underwent 20-gauge vitrectomy.
The anatomic success rates after the initial surgery in the 25-gauge vitrectomy and 20-gauge vitrectomy groups were 93.3% and 91.5%, respectively. The median visual acuity improved significantly from 20/80 preoperatively to 20/30 postoperatively in the 25-gauge group, and from 20/90 to 20/30 in the 20-gauge group.
Good anatomic and functional results were achieved with 25-gauge vitrectomy and the outcomes compared favorably with those of 20-gauge vitrectomy for the treatment of rhegmatogenous retinal detachment.
评估25G经结膜平坦部玻璃体切除术的效果，并将其与20G平坦部玻璃体切除术治疗原发性孔源性视网膜脱离的效果进行比较。
对164例因原发性孔源性视网膜脱离接受平坦部玻璃体切除术的患者的166只眼进行回顾性研究。119只眼接受了25G玻璃体切除术，47只眼接受了20G玻璃体切除术。
25G玻璃体切除术组和20G玻璃体切除术组初次手术后的解剖成功率分别为93.3%和91.5%。25G组的中位视力从术前的20/80显著提高到术后的20/30，20G组则从20/90提高到20/30。
25G玻璃体切除术取得了良好的解剖和功能效果，在治疗孔源性视网膜脱离方面，其效果与20G玻璃体切除术相比具有优势。
