The intraocular foreign body. Principles and problems in the management of complicated cases by pars plana vitrectomy

In a retrospective study, the results of pars plana vitrectomy in treatment of injuries with intraocular foreign bodies were described. The patient material was subdivided into five different groups. In 41.6% of the cases, practical blinding could not be prevented. A visual acuity of 0.2 and better was present in 26.6% of the cases. The preoperative (45%) and postoperative (30%) traumatic retinal detachment have an extremely unfavorable prognosis with a reattachment rate of 40 or 21% respectively. The results in the treatment of injuries with magnetic splitters and their sequelae are very much better than those with nonmagnetic foreign bodies. The gunshot and air rifle pellet injuries were the most unfavorable group.
