To highlight the novel application of anterior segment optical coherence tomography (AS-OCT) to detect corneal silver deposition in a case of ocular argyrosis.
This is a case report and review of the literature.
A 67-year-old man with a 30-year history of chronic occupational exposure to silver-halides secondary to photographic film manufacturing presented with significant ocular argyrosis. His ophthalmic examination was notable for bilateral, widespread pinpoint gray deposits throughout his conjunctiva and cornea at the level of Descemet membrane. Further evaluation with AS-OCT showed deposition in 2 distinct, diffusely hyperreflective bands, corresponding to Bowman layer and Descemet membrane.
AS-OCT provides a useful imaging modality in evaluating corneal deposition diseases. In this case of ocular argyrosis, AS-OCT led to the detection of a hyperreflective Bowman layer and Descemet membrane, representing silver deposition in both these anatomic locations.
强调眼前节光学相干断层扫描（AS-OCT）在检测眼部银质沉着症中角膜银沉积的新应用。
这是一份病例报告并对文献进行了回顾。
一名 67 岁男性，因从事摄影胶片制造的职业性慢性银盐暴露，有 30 年病史，患有明显的眼部银质沉着症。他的眼科检查显示双侧弥漫性针尖状灰色沉积物，遍及整个结膜和角膜达角膜基质层。进一步的 AS-OCT 检查显示，在 2 个不同的弥漫性高反射带中存在沉积，分别对应 Bowman 层和角膜基质层。
AS-OCT 为评估角膜沉积性疾病提供了一种有用的成像方式。在本例眼部银质沉着症中，AS-OCT 检测到 Bowman 层和角膜基质层的高反射性，代表这两个解剖部位的银沉积。
