![]() ![]() ![]() ![]() Corneal stromal pigmentations are secondary to the formation of corneal sequestra, incursions of a limbal melanoma, or the invasion of a pigmented fungus. A corneal epithelial pigmentation is due to the presence of intraepithelial melanocytes, or melanin granules within epithelial cells, and is termed a pigmentary keratitis. In the canine, corneal pigmentation may arise in the corneal epithelium, the corneal stroma, the corneal endothelium, or may extend from an iris prolapse following corneal rupture. This article will concentrate on corneal opacifications arising from pigmentation. These include corneal pigmentation, fibrosis, calcium or lipid deposition, cellular infiltration, the presence of a foreign body, sequestrum, and/or edema. There are several etiologies of corneal opacifications that do not stain with fluorescein. This is the third in a series of articles discussing corneal opacifications. ![]()
