Our experience in intraocular foreign-body removal

Foreign bodies embedded in the retina and choroid that cannot be extracted by a magnet and require vitreous surgery for their removal comprise a separate group. A retrospective review of 40 consecutive cases (between 1977-1990) showed that this type of trauma frequently accompanied extensive ocular damage, including corneal and or scleral perforation, disruption of the lens, significant vitreous hemorrhage, retinal and choroid hemorrhage, and retinal detachment. Intraoperative and late complications occurred frequently, making the visual and structural outcomes of such eyes uncertain; therefore, another alternative must be sought that might improve the prognosis of these eyes. In this review, we emphasize (1) the time elapsed between the accident and the removal of the foreign body and (2) the final visual acuity and the time before the surgery.
