Ocular argyrosis

Abstract

The absorption of silver presents as a grayish coloration in different locations as the skin and eye. Corneal argyrosis is characterized by micro-deposits in the stroma, Bowman or Descemt membranes. This metal could also affect other structures as the retina. We describe the case of a male jeweler with corneal argyrosis. Small whitish–grayish predescemetic depositis were observed by biomicroscopy, which were described as punctate and extra-cellular by in vivo confocal microscopy. Our patient presented a significative impairment of contrast sensitivity under scotopic conditions which could not be attributed to other condition. This test could be helpful in detecting retinal functional alteration before the structural anatomical alteration are visible.
