Retinal Detachment after Vitrectomy; Risk Factors, Pathogenesis, Clinic, and Management

Intraoperative iatrogenic retinal tears leading to postoperative retinal detachments secondary to vitrectomy are an important sight-threatening complication of pars plana vitrectomy. Peripheral vitreous traction and retinal tears that incompletely removed, surgical instruments causing shrinkage on the basis of vitreous and incarceration of the vitreous to the entry points of the surgical instruments during entry and exit can be counted among the main causes of tears. In addition, small ruptures that may have been missed before the operation may cause retinal detachment after PPV. In order to reduce postoperative RD, it is based on the principle of detecting and treating the retinal breaks, if it is formed. Removing the peripheral vitreous completely without traction during PPV is important in preventing the formation of new tears.
