The authors present a retrospective, observational case study of seven patients, who presented with retained Intra-Orbital Foreign Bodies (IOrbFBs) following penetrating orbital injury at a tertiary eye hospital over a period of one year. Cases were reviewed for epidemiological features, mechanism of injury, nature of foreign body, clinical features, imaging modality, associated complications, management outcomes, and the final prognosis. The mean age of presentation was 27.43 years. Amongst the seven patients, two were children (aged <10 years). The male : female ratio was 4 : 3. Of the seven retained IOrbFBs, two were plastic, two wooden, and three metallic in nature (one gunshot injury, one ball projectile (commonly referred to as BB) injury, and one with knife). Two out of seven had no light perception at presentation. The periocular location of the foreign bodies was inferior in 4 cases and medial in 3 cases. Computed Tomography scan confirmed the diagnosis in five cases and Magnetic Resonance Imaging (MRI) was diagnostic in one. Surgical intervention was done in five cases, and two cases were managed conservatively. The authors conclude that favourable outcome can be achieved even without surgical removal in cases of inert metallic/inorganic IOrbFBs. The properties of plastic FBs can frequently render them invisible on imaging, or they may mimic chronic inflammatory conditions like tuberculosis. Long-standing wooden IOrbFBs evade identification radiologically due to prolonged hydration. The ultimate choice of intervention must be individualised, weighing the risks of retention against the risk of iatrogenic damage.
作者进行了一项回顾性观察性病例研究,研究对象为7例患者,他们在一家三级眼科医院因眼眶穿透伤而出现眼眶内异物残留(IOrbFBs),为期一年。对病例进行了流行病学特征、损伤机制、异物性质、临床特征、影像学检查方式、相关并发症、治疗结果及最终预后的评估。患者的平均就诊年龄为27.43岁。7例患者中,2例为儿童(年龄<10岁)。男女比例为4:3。7例残留的IOrbFBs中,2例为塑料异物,2例为木质异物,3例为金属异物(1例枪伤,1例弹丸伤(通常称为BB弹伤),1例刀伤)。7例中有2例就诊时无光感。异物位于眼周下方的有4例,位于内侧的有3例。计算机断层扫描(CT)在5例中确诊,磁共振成像(MRI)在1例中具有诊断价值。5例进行了手术干预,2例采取保守治疗。作者得出结论,对于惰性金属/无机眼眶内异物,即使不进行手术取出也可获得良好预后。塑料异物的特性常常使其在影像学上不可见,或者可能类似于结核病等慢性炎症性疾病。长期存在的木质眼眶内异物由于长期水化而在放射学上难以识别。最终的干预选择必须个体化,权衡异物残留的风险与医源性损伤的风险。
