The intraocular foreign body

Abstract

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.

Management of postequatorial magnetic intraretinal foreign bodies

“…The fibrous capsules were very thick, the foreign bodies very small, ~ind as they did not elevate from the retinal surface, they may well have been captured within the scleral wall. The danger of their forced removal could have been greater than their presence [6]. Regular follow-up examinations with visual acuity, slit-lamp biomicroscopy, indirect binocular ophthalmoscopy, ERG, and dark adaptation have been carried out revealing no signs of siderosis so far.…”

“…While intravitreal foreign bodies can be extracted either by a magnet or with forceps [4,9], an intraretinal foreign body is better removed with a special forceps to avoid dragging of the retina [2,6].…”
