PATIENTS AND METHODS: This retrospective r eview examined consecutive cases of ocular injury associated with intraocular fo reign bodies; 71 eyes included had a single metallic intraocular foreign body (< 5 mm) located in the vitreous cavity removed by external magnet or intraocular forceps. Variables included preoperative and postoperative visual acuity, retina l break formation, retinal detachment, presence of an afferent pupillary defect, intraocular pressure, entrance site, foreign body size, method of extraction, a nd time between occurrence and surgical extraction. RESULTS: Factors predictive of good visual outcome (visual acuity >20/200) were: shortest interval between t rauma and foreign body extraction, preoperative visual acuity of 20/200 or bette r, and absence of afferent pupillary defect. CONCLUSIONS: In this nonrandomized study, good visual results could be obtained in eyes undergoing prompt foreign b ody removal, especially those with good preoperative visual acuity and no affere nt pupillary defect.展开更多
