A case of simultaneous bilateral herpetic epithelial keratitis.

The patient, a 56-year-old man, presented with dendritic keratitis in the right eye and geographic keratitis in the left, with decreased corneal sensation in both eyes. The virus isolated from both eyes was identified as herpes simplex virus (HSV-1) by the indirect immunofluorescent method using anti-HSV-1 monoclonal antibody. Antibody tests of paired sera suggested that the epithelial lesions were not primary but recurrent. No significant difference was observed in DNA cleavage patterns between the virus isolates obtained bilaterally.
