title: Primary herpes simplex subepithelial dendritic keratitis.
abstract: A 37-year-old man developed an acute follicular conjunctivitis with preauricular lymphadenopathy believed to be epidemic keratoconjunctivitis. On the eighth day of his disease, subepithelial dendritic opacities developed in the cornea which were not typical of either epidemic keratoconjunctivitis or herpetic keratitis. A diagnosis of primary herpes simplex virus infection was established by positive viral culture and a rise in serum antibody titer to herpes simplex virus. Subepithelial dendritic keratitis as a manifestation of herpes simplex infection of the cornea has not been previously described. The lesions seen in this patient were not reproducible in rabbits and we believe they represent an unusual host response to the virus. This form of herpetic keratoconjunctivitis is extremely difficult to differentiate from epidemic keratoconjunctivitis. Corticosteroids should be used with caution in cases that are not completely typical of epidemic keratoconjunctivitis.
