[Pars plana vitrectomy techniques guiding by the pathological anatomy in rhegmatogenous retinal detachment]

Rhegmatogenous retinal detachment (RRD) is a retinal vitreous disease, with increasing incidence in recent years. Pars plana vitrectomy is one of the most common treatments for RRD. To prevent re-detachment after the primary surgery and guarantee the visual outcome of the patients, we highlight the techniques for RRD during the PPV, including the surgical skills to manipulate the breaks, peripheral retina and vitreous base, meanwhile, empathized on the posterior vitreous detachment and posterior vitreous cortex. The aim is to increase the rate of anatomical re-attachment and to improve visual function.孔源性视网膜脱离（RRD）的发病率逐年升高。玻璃体切除术（PPV）是治疗RRD的重要手术方式之一，提高PPV的成功率对于患者视力预后具有重要意义。本述评以玻璃体视网膜组织解剖特点为基础，提出了针对玻璃体视网膜交界面处理RRD的手术技术要点，包括裂孔周围玻璃体，周边部视网膜玻璃体和玻璃体基底部的操作要点以及人工玻璃体后脱离和玻璃体后皮质的处理。旨在通过提高手术技术，降低复发性视网膜脱离的发生率，提升患者术后视功能。.
