Euphorbia trigona toxic keratopathy

Abstract

Background: African milk tree (Euphorbia trigona) sap contains toxic components, notably ingenol esters, causing cytotoxicity to corneal cells and hindering healing, thereby causing toxic keratopathy.

Case report: We present a case of ocular injury in a 45-year-old man following exposure to Euphorbia trigona sap during gardening. Despite immediate irrigation, the patient experienced discomfort, redness, and reduced vision in his right eye. Treatment involved aggressive topical antibiotics and subsequent corneal debridement.

Conclusion: Euphorbia trigona sap contains cytotoxic properties results in defective corneal epithelial healing. Understanding variations in latex compositions across species aid in clinical anticipation and individualised treatment.
