OMNICIDE® is a broad-spectrum animal health disinfectant containing glutaral-dehyde and cocobenzyl dimethyl ammonium chloride. Ocular chemical injury caused by animal health disinfectant has never been described in the previous literature. Herein, we presented a 57-year-old man who mis-instilled animal health disinfectant into his right eye. Extensive conjunctival chemosis, large corneal epithelial defect, and limbal ischemia were noted in his right eye with Dua classification grade III. In addition to the conventional medical therapy, we used the biologic corneal bandage device, PROKERA®, to stabilize the ocular surface inflammation and promote corneal re-epithelialization. The corneal epithelial defect healed completely, and the visual acuity improved and remained stable during the follow-up period.
