Migration of retained tarsal bee stinger onto the ocular surface causing superficial keratopathy

Abstract

We report a case of keratopathy due to retained stinger elements following a bee sting and envenomation of the ocular adnexa. A 48-year-old woman presented with a 2-day history of right-sided eye pain, photophobia, and reduced visual acuity. Six days prior to presentation, she had been stung on the right upper eyelid by a bee. Her usual practitioner had removed the stinger and commenced a course of oral antibiotics. Anterior segment examination revealed coarse linear abrasions and superficial punctate keratitis with associated epithelial edema. Eversion of the right upper eyelid revealed the presence of retained stinger lancets near the medial eyelid margin.  The retained stinger was removed, and the patient responded well to treatment with topical antibiotics, steroids, and cycloplegia.
