Persistent epithelial defect after penetrating keratoplasty caused by adenoviral infectious keratitis

A causal role of herpes simplex infection in persistent epithelial defect following penetrating keratoplasty (PKP) has been documented in the past. Instead, not much information is available on the role of adenovirus infection in delayed epithelization following PKP. Here, we describe a case of persistent epithelial defect due to adenoviral infection keratitis confirmed by PCR analysis. Adenovirus keratitis can be an unusual cause of delayed epithelization after PKP.
