PURPOSE
To describe a case of left eye corneal perforation, cataract, hyphema, and intraocular foreign body after airsoft pellet injury.
METHODS
The authors reviewed the medical history and diagnostic imaging of a 12-year-old boy injured by a pellet from an airsoft gun. Typically, plastic airsoft pellets cause blunt trauma to the globe, which can lead to visual disability from corneal abrasion or hyphema. Initial computed tomography of the left orbit showed a 6.1 mm × 7.6-mm radiodense foreign body with beam-hardening artifact, a radiographic feature associated with metallic objects.
RESULTS
The patient was taken to the operating room for globe repair, lensectomy, vitrectomy, and removal of intraocular foreign body. The removed foreign body was a plastic airsoft pellet.
CONCLUSION
This is the first report of a plastic intraocular foreign body showing beam-hardening artifact. This finding may have implications in the diagnosis and management of retained intraocular or intraorbital plastic foreign bodies.
目的
描述一例气枪软弹损伤后出现左眼角膜穿孔、白内障、前房积血和眼内异物的病例。
方法
作者回顾了一名12岁男孩被气枪软弹击伤的病史和诊断影像。通常，塑料气枪软弹会对眼球造成钝挫伤，可导致因角膜擦伤或前房积血而致视力残疾。左眼眼眶的初始计算机断层扫描显示一个6.1毫米×7.6毫米的高密度异物，并伴有束硬化伪影，这是一种与金属物体相关的影像学特征。
结果
患者被送往手术室进行眼球修复、晶状体切除术、玻璃体切除术和眼内异物取出术。取出的异物是一枚塑料气枪软弹。
结论
这是关于显示束硬化伪影的塑料眼内异物的首例报告。这一发现可能对眼内或眶内留存塑料异物的诊断和处理具有启示意义。
