title: An analytical electron microscopic study of a corneal tattoo.
abstract: A case of corneal tattoo was studied histologically, and by electron microscopy. Most of the electron dense granules were seen in keratocytes, either singly or in clumps; some were found between collagen fibrils. Platinum was localized in the granules by means of x-ray microanalysis.
