Clinical findings in 3 cases of ocular injuries caused by the milky latex from Euphorbia tirucalli and Dieffenbachia sequine were reported. The initial symptoms of all patients were burning pain with subsequently blurred vision. Visual acuity was reduced between 6/30 and 6/20. Euphorbia sap caused punctate erosion, microbullae and Descemet's folds; while Dieffenbachia sap induced conjunctival chemosis and fine blue crystals in the stroma. Ocular symptoms developed in 5 to 18 hours despite immediately copious irrigation. Supportive treatment resulted in a full recovery without sequalae over 1 week. Wearing eye protection and washing the exposed areas with soap and water are advised while handling such plants.
