To identify the presence of silver deposits in the cornea using a new-generation confocal microscopy technique.
Case report.
A 70-year-old man, who had been a jeweler for many years, was referred to our center for assessment of corneal opacity and ocular pigmentation. Slit-lamp examination revealed grayish, dense confluent deposits in the central and peripheral cornea, deep stroma, and Descemet's membrane. On confocal microscopy, we observed typical images of hyperreflective keratocytes across the entire stromal surface and two hyperreflective plaques coinciding with areas of metal deposition, one at Descemet's membrane and the other at Bowman's membrane. This last deposition site has not been previously identified in vivo by confocal microscopy.
Confocal microscopy is a useful tool for the diagnosis of corneal argyrosis because it allows the in vivo visualization of silver deposits at different corneal levels.
使用新一代共焦显微镜技术来确定角膜中是否存在银沉积。
病例报告。
一名 70 岁男性,多年来一直是珠宝商,因角膜混浊和眼部色素沉着被转至我们中心进行评估。裂隙灯检查显示中央和周边角膜、深基质和 Descemet 膜有灰色、密集融合的沉积物。在共焦显微镜下,我们观察到整个基质表面有典型的高反射性角膜细胞图像,以及两个高反射性斑块,与金属沉积区域相对应,一个在 Descemet 膜上,另一个在 Bowman 膜上。这个沉积部位以前在体内没有通过共焦显微镜来识别。
共焦显微镜是诊断角膜含银沉着症的有用工具,因为它可以在体内不同的角膜水平可视化银沉积。
