Pterygium is a common conjunctival degeneration and surgical excision is the mainstay of treatment. HSV keratitis after ocular surgery has been attributed to various factors including reactivation of latent infection secondary to surgical trauma to the corneal subepithelial nerve plexus and the modulation of the ocular immune response in the postoperative period caused by steroids. In the current case, the patient had persistent epithelial defect which was non responsive to routine topical lubricant therapy and showed a classical dendritic ulcer pattern upon staining with fluorescein dye. Upon initiation of conventional anti-viral therapy, the patient improved and the epithelial defect was gradually healed. HSV keratitis can rarely present as a non-healing epithelial defect after pterygium surgery and a close follow-up in the post-operative period, timely diagnosis and prompt antiviral therapy plays an important role in achieving a favourable clinical outcome in such cases.
