Migration of an intraocular, nonmagnetic foreign body from a site near the disc toward a corneal portal of entry is a rare event. The following report of a case of this type illustrates some of the mechanisms involved in the migration of intraocular foreign bodies.
Report of Case
A 19-year-old white youth was admitted to the Illinois Eye and Ear Infirmary on April 8, 1962, for treatment of a penetrating injury to the right eye. One hour prior to admission the patient had been standing 5 feet from a friend who was firing a 22 open-chamber revolver at a tin can. At the instant of firing the patient felt something fly into the right eye. This was accompanied by pain and blurring of vision of the right eye.Pertinent physical findings were limited to the right eye. The visual acuity was counting fingers at 2 feet with excellent light projection.
