Herpes simplex keratitis in renal transplant recipients.

Herpes simplex epithelial keratitis developed in four renal transplant recipients while they were receiving high-dose systemic corticosteroid and immunosuppressive therapy. In all cases the presentation was atypical, and in two cases the course was protracted, leading to some visual loss from corneal scarring and opacification. With the immunocompromised patient it is important to seek early ophthalmologic consultation when even minor ocular symptoms develop.
