Determining the precise location of intraocular foreign bodies is crucial for the management of patients with open-globe injury. Computed tomography is the most common method for detecting intraocular foreign bodies in the posterior segment. In this article, we describe three cases of open-globe injury with different types of intraocular foreign bodies in the posterior segment that were accurately located using computed tomography scans and B-scan ultrasonography.
Each of the three cases of open-globe injury described in this report had different types of ocular trauma, clinical symptoms, and intraocular foreign bodies. Computed tomography scans showed the exact location of the intraocular foreign bodies in the posterior segment in two of the three cases. A B-scan ultrasound was used to determine the location of a non-metallic intraocular foreign body in the third case. All three patients had intraocular foreign bodies, and one of them had an additional orbital foreign body. Case 1 had a perforating eye injury with the additional intraorbital foreign body; Cases 2 and Case 3 had different types of intraocular foreign bodies and prognoses. Various treatment approaches were used, ranging from observation to surgery, depending on the location of the intraocular foreign bodies, and all cases were successfully managed. These three cases show that proper use of various types of imaging tests is indispensable in the context of an intraocular foreign body related to open-globe injury.
Imaging techniques are crucial for the detection of an intraocular foreign body, and computed tomography is one of the simplest and most useful, especially in cases of open-globe injury.
确定眼内异物的精确位置对于开放性眼球损伤患者的治疗至关重要。计算机断层扫描是检测后段眼内异物最常用的方法。在本文中，我们描述了三例开放性眼球损伤病例，后段存在不同类型的眼内异物，通过计算机断层扫描和B超超声检查准确确定了异物位置。
本报告中描述的三例开放性眼球损伤病例，每例都有不同类型的眼外伤、临床症状和眼内异物。计算机断层扫描在三例中的两例显示了后段眼内异物的确切位置。在第三例中使用B超超声来确定非金属眼内异物的位置。所有三名患者都有眼内异物，其中一名患者还有眶内异物。病例1为眼球穿孔伤并伴有眶内异物；病例2和病例3有不同类型的眼内异物和预后情况。根据眼内异物的位置，采用了从观察到手术的各种治疗方法，所有病例均成功处理。这三例表明，在与开放性眼球损伤相关的眼内异物情况下，正确使用各种类型的影像学检查是必不可少的。
成像技术对于检测眼内异物至关重要，计算机断层扫描是最简单且最有用的方法之一，尤其是在开放性眼球损伤病例中。
