[Indications for pars plana vitrectomy after perforating injuries (author's transl)].

A preliminary report is given on 100 consecutive cases of pars plana vitrectomy after perforating injuries due to nonmagnetic IOFB (9 cases), magnetic IOFB (32 cases) and lacerating injuries (19 cases). Pars plana vitrectomy was performed to remove persistent vitreous membranes, to prevent proliferative transformation with following retinal detachment or to make the IOFB become visible for extraction. These eyes were practically amaurotic but in 43 cases out of 100 a positive results could be achieved (i.e. the retina being attached, posterior pole becoming visible). Indications, technique and complications of both pars plana vitrectomy and FB extraction are discussed. As a result pars plana vitrectomy should be performed within an interval of at least 2 weeks after the first intervention (i.e. wound closure of FB extraction).
