A case of bilateral palytoxin-induced keratoconjunctivitis is presented. A 63-year-old man presented to the emergency department with symptoms of red eye, purulent discharge, and foreign body sensation in both eyes. On slit lamp examination, epithelial defects in both eyes with a ring-shaped corneal stromal infiltrate in the right eye and a marginal stromal infiltrate in the left eye were noted. High-resolution anterior segment optical coherence tomography (HR-AS-OCT) showed stromal hyperreflectivity and Descemet folds. Bacterial, fungal and amoebic cultures were taken. Empirical treatment with topical dexamethasone as well as antibiotics and systemic doxycycline was started.
The next day the patient informed that he had been handling zoanthid coral without gloves and had rubbed his eyes after. A bilateral palytoxin-caused keratoconjunctivitis was diagnosed. His eyes were irrigated abundantly with saline solution, and umbilical cord serum eye drops were added to the treatment. The treatment was tapered according to the corneal infiltrates and epithelial defects improvement.
After four months, the stromal infiltrates were resolved, and corneal scars persisted in both eyes. HR-AS-OCT showed anterior stromal hyper-reflectivity corresponding to corneal leucomas.
Palytoxin is a toxin produced by corals like zoanthid coral. It can cause ocular adverse effects such as keratolysis and corneal inflammation, and in some cases, it can lead to corneal perforation. It can also produce systemic adverse effects, hence the importance of the preventive measures when handling corals that can produce the toxin.
