METHODS: A 74-year-old woman with a history of rheumatoid arthritis visited a local clinic because of right eye discomfort that had persisted for 5 months. Eversion of the upper eyelid revealed an embedded foreign body, and she was referred to our hospital. A transparent and smooth-surfaced foreign body was found embedded at the center of the upper eyelid conjunctiva. Additionally, fatty tissues were found behind the foreign body. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a foreign body rich in water at the same site. The foreign body was a spherical object with a diameter of 9 mm reaching as deep as the tarsus. On removal, the foreign body was identified as an RGP contact lens. On further questioning, it was discovered that the patient had lost an RGP contact lens 7 years earlier. The symptoms disappeared after removal of the foreign body.
CONCLUSIONS: RGP contact lenses are not detected on MRI scans, but cysts around the lenses are detected, which may result in multiple detections. CT cannot differentiate a foreign body from granulation tissue. The foreign body itself or a reactive granuloma can be seen when the eyelid is everted.
CONCLUSIONS: A contact lens embedded in the eyelid without symptoms is rare but can be detected via a detailed interview, visual examination, and diagnostic imaging.
方法:一名74岁有类风湿性关节炎病史的女性因右眼不适而到当地诊所就诊,并持续了5个月。上眼睑的外翻显示了一个嵌入的异物,她被转诊到我们医院.发现透明且表面光滑的异物嵌在上眼睑结膜的中心。此外,在异物后面发现了脂肪组织。计算机断层扫描(CT)和磁共振成像(MRI)显示同一部位有富含水的异物。异物是直径为9毫米的球形物体,其深度与the骨一样深。拆卸时,异物被鉴定为RGP隐形眼镜.在进一步的提问中,发现患者7年前失去了RGP隐形眼镜。取出异物后症状消失。
结论:MRI扫描未检测到RGP隐形眼镜,但是晶状体周围的囊肿被检测到,这可能导致多次检测。CT不能区分异物和肉芽组织。当眼睑外翻时,可以看到异物本身或反应性肉芽肿。
结论:隐形眼镜嵌入眼睑而没有症状是罕见的,但可以通过详细的访谈来检测,目视检查,和诊断成像。
