Adherence of fluorescein sodium dye to diseased epithelial cells, a hitherto unreported phenomenon, was captured in photomicrographs in severe herpes zoster and keratoconjunctivitis sicca keratopathies. It is notable that this phenomenon differs completely from the well known fluorescent property of the dye penetrating into defective corneal epithelium, and that the staining pattern shown by adherent fluorescein correlates well with the staining pattern shown by rose bengal dye.

The authors describe 19 patients with toxic ulcerative keratopathy. These patients were referred with other diagnoses and were victims of overtreatment. Fourteen of these patients had iatrogenic toxic keratopathy, and the other five had self-induced keratoconjunctivitis. The corneal defects tended to be inferior or inferonasal and associated with an intense, coarse superficial keratitis in "comet's impact" fashion. Conjunctival hyperemia, chemosis, and conjunctival staining were considerably more prominent inferiorly and inferonasally. Diagnosis was the key element in management. Treatment consisted of discontinuation of the offending medication or preservative. Other important measures included preservative-free medications, patching, therapeutic contact lenses, goggles, and viscoelastic agents. Many of the patients with iatrogenically induced toxic keratopathy had significant ocular surface disease such as keratoconjunctivitis sicca (6 patients), previous intraocular surgery (6 patients), herpes simplex infection (1 patient), or herpes zoster infection (1 patient).
