Of 105 eyes with ocular injuries involving retained intraocular foreign bodies, 63 (60%) had a final visual acuity of 20/40 or better; 20 (19%) were 20/50 to 5/200; and 15 (14%) were worse than 5/200. Six eyes (6%) were enucleated. The extent of visual recovery was limited in selected cases by the characteristics of the initial injury. Multivariate analysis was used to identify prognostic factors. Predictive of a good visual outcome (greater than or equal to 20/40) were: (1) initial visual acuity better than 20/40 and (2) the need for only one or two operations in the treatment of the injury. Predictive of a poor visual outcome (less than 5/200) were: (1) initial visual acuity worse than 5/200 and (2) a wound 4 mm or longer in length, independent of wound location. The visual outcome in this series of patients was compared with other large series of intraocular foreign bodies reported before the development of vitreous microsurgical techniques. The percentage of patients with a visual outcome of 20/40 or better has remained the same, whereas the incidence of enucleation has diminished.
在105例伴有眼内异物残留的眼外伤患者中，63例（60%）最终视力达到20/40或更好；20例（19%）为20/50至5/200；15例（14%）低于5/200。6例（6%）眼球被摘除。在部分病例中，视功能恢复程度受初始损伤特征限制。采用多因素分析确定预后因素。预测良好视力结果（大于或等于20/40）的因素为：（1）初始视力优于20/40；（2）损伤治疗仅需一至两次手术。预测不良视力结果（低于5/200）的因素为：（1）初始视力低于5/200；（2）伤口长度4mm或更长，与伤口位置无关。将该系列患者的视力结果与玻璃体显微手术技术发展之前报道的其他大量眼内异物病例进行比较。视力结果为20/40或更好的患者百分比保持不变，而眼球摘除率有所下降。
