Bilateral herpes simplex keratitis reactivation after lacrimal gland botulinum toxin injection

We report a case of a 59-year-old female injected with 2.5 units of BTA injection in each lacrimal gland for functional epiphora. The patient had a history of herpes simplex viral keratitis that was quiescent for more than 2 years. After 3 weeks, she developed reactivation of viral keratitis bilaterally, which was successfully managed with antivirals and topical steroids. Reactivation of quiescent herpes simplex keratitis is a possibility after lacrimal gland BTA and caution should be exercised in such cases.
