PURPOSE
This case report aims to describe a rare case of asymptomatic retained metallic intraocular foreign body (IOFB) in the retina with reduced full-field electroretinography (ff-ERG) in a Chinese woman.
METHODS
This is a clinical investigation of a patient who unexpectedly presented with a metallic IOFB at the superior-temporal region of the left eye ring during a brain computed tomography.
RESULTS
Her best-corrected visual acuity was 20/20 in both eyes. The dilated fundus photograph of the left eye revealed a metallic IOFB in the retina. She reported no ocular symptoms. A diagnosis of asymptomatic metallic IOFB was made definitely. The subsequent ff-ERG demonstrated subnormal amplitudes of dark and light adaption in the left eye, whereas responses were normal in the right eye.
CONCLUSIONS
Our findings suggest the application of ff-ERG has important benefits for evaluating the visual function in patients with retained IOFB.
目的
本病例报告旨在描述一名中国女性视网膜中罕见的无症状金属性眼内异物（IOFB）且全视野视网膜电图（ff-ERG）降低的病例。
方法
这是一项对一名患者的临床研究，该患者在脑部计算机断层扫描期间意外发现左眼环颞上区域有金属性IOFB。
结果
她双眼的最佳矫正视力均为20/20。左眼散瞳眼底照片显示视网膜中有金属性IOFB。她未报告眼部症状。明确诊断为无症状金属性IOFB。随后的ff-ERG显示左眼暗适应和明适应的振幅低于正常，而右眼反应正常。
结论
我们的研究结果表明，ff-ERG的应用对评估留存IOFB患者的视觉功能具有重要意义。
