title: Morphology of epithelial keratitis in herpes zoster ophthalmicus. A non-contact photomicrographic in vivo study in the human cornea.
abstract: OBJECTIVE
  To investigate the in vivo morphology of epithelial changes in acute herpes zoster keratitis.
  
  
  METHODS
  10 patients with acute disease. In 7, systemic acyclovir treatment was started at presentation, in 2 < or = 24 hours before, 1 was not treated. The corneae were examined with the slit lamp, followed intermittently for 3-30 days, and photographed at intervals ranging between 1 to 7 days.
  
  
  RESULTS
  All but one patient had epithelial changes at presentation; all developed new ones. The smallest discernible entities were abnormal cells of about 10-15 microm in diameter, singular or grouped. Larger foci measured about 100-200 microm. 2 patients showed pseudodendrites at presentation, and further 3/9 observed > or = 2 weeks developed them. Some lesions showed white surface plaques. No ulcerations were observed. Healing occurred < or = 10-22 days after the onset of symptoms.
  
  
  CONCLUSIONS
  The study seemed to have followed the natural course of the disease. The rapidly changing morphology in the absence of ulcerative features indicated successive damage counteracted by reparative forces.
