[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.
