Abstract
Two glaucomatous patients had a clinical picture of atypical band keratopathy develop several years after local antiglaucoma treatment, including pilocarpine, tiloptic, and epinephrine. These medications consisted of three preservatives: benzalkonium chloride, edetate disodium tetra acetate (EDTA), and boric acid. The combination of benzalkonium chloride and EDTA was reported to cause a toxic effect on superficial stromal keratocytes. It is assumed that this atypical band keratopathy has developed in a primarily degenerated superficial stroma, which is associated with the toxic effect of this combination of three preservatives.
