%X Purpose. To evaluate the confocal microscopy findings of a 46-year-old male with bilateral biopsy proven argyrosis. Materials and Methods. Besides routine ophthalmologic examination, anterior segment photography and confocal microscopy with cornea Rostoch module attached to HRT II (Heidelberg Engineering GmbH, Heidelberg, Germany) were performed. Findings. Squamous metaplastic changes on conjunctival epithelium and intense highly reflective extracellular punctiform deposits in conjunctival substantia propria were detected. Corneal epithelium was normal. Highly reflective punctiform deposits starting from anterior to mid-stroma and increasing through Descemet¡¯s membrane were evident. Corneal endothelium could not be evaluated due to intense stromal deposits. Conclusion. Confocal microscopy not only supports diagnosis in ocular argyrosis, but also demonstrates the intensity of the deposition in these patients. 1. Introduction Prolonged exposure to silver might cause irreversible pigmentation of the skin (argyria) and/or the eyes (argyrosis) [1]. Hands, eyes, and mucous membranes are affected in most of the patients, and discoloration of the ocular surface is the main ocular evidence [1¨C3]. A direct relationship was shown between the amount of discoloration and the length of time worked [1]. Confocal microscopy provides high-resolution, high-contrast in vivo images and is a powerful tool for studying the ultrastructure of the cell, its molecular components, and their functions. The Rostock cornea module is an option of the Heidelberg Retina Tomograph (HRT II, Version 3.0; Heidelberg Engineering GMBH, Dossenheim, Germany) introduced as an improvement over older confocal microscopes. The module consists of a monochrome laser radiation source which avoids chromatic aberrations and provides extremely sharp images and a high-powered lens that allows the operator to change the confocal plane within the cornea to capture images at different depths without losing sharpness [4]. The aim of this study is to demonstrate the location of conjunctival and corneal silver deposits by confocal microscopy and to evaluate the correlation between conjunctival histopathology and confocal microscopy findings in a case of occupational argyrosis. To the best of our knowledge this is the first biopsy proven argyrosis case to be evaluated by confocal microscopy. 2. Report of a Case A 46-year-old long-standing silver worker who was diagnosed as ocular argyrosis 4 years earlier was evaluated with confocal microscopy. His visual acuity was 10/20 and intraocular pressures were normal
