Anterior Segment Optical Coherence Tomography in Ocular Argyrosis.

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 male with a 30-year history of chronic occupational exposure to silver-halides secondary to photographic film manufacturing presented with significant ocular argyrosis. His ophthalmic exam was notable for bilateral, widespread pinpoint grey deposits throughout his conjunctiva and cornea at the level of Descemet’s membrane. Further evaluation with AS-OCT showed deposition in two distinct, diffusely hyper-reflective bands, corresponding to Bowman’s layer and Descemet’s 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 hyper-reflective Bowman’s layer as well as Descemet’s membrane, representing silver deposition in both of these anatomic locations.

强调前段光学相干断层扫描（AS - OCT）在一例眼部银质沉着病中检测角膜银质沉积的新应用。 这是一篇病例报告及文献综述。 一名67岁男性，有30年因胶片制造而长期职业性接触卤化银的病史，出现明显的眼部银质沉着病。他的眼科检查显著特征为双侧结膜和角膜的德斯密膜层面广泛存在针尖状灰色沉积物。通过AS - OCT进一步评估显示，在两个不同的、弥漫性高反射带存在沉积，分别对应于鲍曼层和德斯密膜。 AS - OCT为评估角膜沉积性疾病提供了一种有用的成像方式。在这例眼部银质沉着病中，AS - OCT检测到高反射的鲍曼层以及德斯密膜，表明在这两个解剖位置均存在银质沉积。
