Abstract

The authors studied the hospital records of 47 patients(47 eyes) with ocular injuries involving retained intraocular foreign bodies at the Kyungpook National University Hospital from March 1985 through March 1990. Forty-two(89%) of the 47 patients were male and the third decade occupied about 40% of all cases. Most of the IOFB was located at the posterior segment and the size was usually 2-10 mm2. The nature of IOFB was mostly magnetic. The injury was due to hammering in 45% of the cases. The most frequent preoperative complication of IOFB were lens opacity(30%), followed by hyphema(21%) and vitreous hemorrhage(15%). Predictive indicators of good visual outcome(20.5) were: 1) the more anteriorly located in the eyeball; 2) the smaller size of IOFB less than 10 mm2; 3) initial visual acuity better than 0.1; 4) a wound size 3mm or less in length; 5) the need for only 0ne or two operations in the treatment of the injury.
