case_images: He had been under regular observation by his ophthalmologist because of recurrent herpes simplex keratitis in his left eye from 8 years before the first visit.  Figure 1 shows a slit-lamp photograph of the patient's left eye 6 years before the first visit.
case_images: Slit-lamp photographs of the patient's left eye at his initial visit. Slit-lamp examination revealed corneal perforation (a). Corneal epithelial defects were seen using fluorescein staining (b). The space in his left anterior chamber had almost disappeared (c).
