Corneal foreign bodies are reported to be the second most common type of ocular injury. Anterior segment optical coherence tomography (AS-OCT) is a valuable tool for the early diagnosis and monitoring the progress of treatment in cases of ocular trauma. Herein we aimed to report on a patient with an intra-corneal foreign body and the role of AS-OCT in management.
A 34-year-old male presented with foreign body sensation in his left eye. Slit-lamp biomicroscopic examination revealed a peripherally located intrastromally embedded foreign body with a free anterior edge extending outwards from the cornea. It was not possible to visualize the foreign body's entire route through the cornea because of localized corneal edema. AS-OCT showed shadowing of the corneal layers corresponding to the location of the corneal foreign body. A hyper-reflective lesion was observed close to the inside edge of the foreign body in the cornea, indicating that the foreign body had not completely penetrated the cornea. The foreign body was removed via the external route, as it had not completely penetrated the cornea. During the postoperative period the patient was asymptomatic, although the left eye's cornea healed with scar tissue.
AS-OCT facilitates non-invasive rapid imaging of ocular tissue at va rious depths, thereby providing accurate assessment of foreign body characteristics.The location of an intracorneal foreign body and the status of the surrounding ocular structure dictate the optimal surgical technique to be employed.
AS-OCT in the present case facilitated localization and determination of the size of a corneal foreign body. In addition, AS-OCT findings assisted in selection of the appropriate surgical intervention.
据报道，角膜异物是第二常见的眼外伤类型。眼前段光学相干断层扫描（AS-OCT）是眼外伤早期诊断和监测治疗进展的重要工具。在此，我们旨在报告一例角膜内异物患者以及AS-OCT在治疗中的作用。
一名34岁男性因左眼有异物感就诊。裂隙灯生物显微镜检查发现角膜基质层周边有一嵌入的异物，其游离的前缘从角膜向外延伸。由于局部角膜水肿，无法看清异物在角膜内的完整路径。AS-OCT显示与角膜异物位置相对应的角膜各层有阴影。在角膜异物内缘附近观察到一个高反射病变，表明异物未完全穿透角膜。由于异物未完全穿透角膜，通过外部途径将其取出。术后患者无症状，尽管左眼角膜愈合后留下了瘢痕组织。
AS-OCT有助于对不同深度的眼组织进行无创快速成像，从而准确评估异物特征。角膜内异物的位置和周围眼结构的状况决定了应采用的最佳手术技术。
本病例中，AS-OCT有助于角膜异物的定位和大小测定。此外，AS-OCT的检查结果有助于选择合适的手术干预方式。
