BB injuries continue to be one of the most common causes of severe ocular injury among adolescent males. Extraocular and nonperforating anterior globe injuries most commonly result in favorable visual outcomes. The appropriate medical management of both perforating and nonperforating anterior globe injuries resulting from BB trauma and their potential ocular sequelae are reviewed.
Three cases illustrating typical as well as atypical anterior globe injuries caused by BBs are presented. Two cases involve nonperforating anterior globe injuries--one with intracranial and one with intraorbital involvement. The third involves a retained intraocular foreign body. The biomicroscopic and ophthalmoscopic features of these injuries are discussed, as are potential complications and management strategies associated with these types of trauma.
Injuries associated with intraocular BBs often result in enucleation if functional vision is not salvageable. Sequelae to such injuries include endophthalmitis, traumatic hyphema, ocular siderosis, and sympathetic ophthalmia. Plain-film radiography and axial computed tomography are critical first steps in determination of the position of any intracranial or intraorbital metallic foreign body. Routine observation for the development of ocular sequelae resulting from retained intraocular, intracranial, and intraorbital BB injuries is recommended.
气枪铅弹伤仍是青少年男性严重眼外伤最常见的原因之一。眼外和非穿孔性前眼球损伤通常会带来良好的视觉预后。本文综述了气枪铅弹创伤导致的穿孔性和非穿孔性前眼球损伤的适当药物治疗及其潜在的眼部后遗症。
本文介绍了3例说明气枪铅弹导致的典型和非典型前眼球损伤的病例。2例为非穿孔性前眼球损伤,1例累及颅内,1例累及眶内。第3例涉及眼内异物存留。文中讨论了这些损伤的生物显微镜和检眼镜特征,以及与这类创伤相关的潜在并发症和处理策略。
如果无法挽救功能性视力,眼内气枪铅弹伤常导致眼球摘除。此类损伤的后遗症包括眼内炎、外伤性前房积血、眼铁质沉着症和交感性眼炎。普通X线摄影和轴向计算机断层扫描是确定任何颅内或眶内金属异物位置的关键的第一步。建议对因眼内、颅内和气枪铅弹伤导致的眼部后遗症的发生进行常规观察。
