Jellyfish sting injury to the cornea

Abstract

A 25-year-old woman presented to the emergency room 2 hours after a Jellyfish sting to the left eye. Centrally located linear epithelial defects were observed on slit-lamp evaluation. The epithelial defects improved but did not heal totally after meticulous patching with antibiotic ointment and cycloplegic drops. Small, subepithelial negative staining areas within the epithelial defects were observed on day 3. Confocal microscopy was performed and revealed thread-like hyperreflective structures, mainly located at the basal epithelial layer. Following debridement of the traumatized areas, the corneal epithelium healed completely in 24 hours, resulting in increased visual acuity and decreased foreign body sensation. Jellyfish stings to the eye may involve the intrusion of the nematocysts, thread-like venomous structures, into the cornea. Debridement of these foreign bodies can be helpful in the treatment of resistant cases.
