Objective: To present the successful outcome of regenerating agent (RGTA) treatment in a patient with severe ocular surface chemical injury.Methods: Case reportResults: A 14-year-old female patient was admitted to our clinic following chemical burn in the left eye. Her best corrected visual acuity (BCVA) was 20/40; and she had total corneal and 75% conjunctival epithelial loss, corneal haze, and limbal ischemia for nine clock hours in the left eye. The patient had already received standard therapy consisting of patching, preservative-free artificial tears, topical netilmicin, topical dexamethasone, oral doxycycline, and vitamin C for two weeks. We initially cleaned the conjunctival necrotic tissues, applied the silicon hydrogel bandage contact lens, exchanged the topical netilmicin with preservative-free moxifloxacin and supplemented this therapy with RGTA (Cacicol20, Paris, France) once in two days. The BCVA of the patient improved to 20/20 and the ocular surface re-epithelization was completed on day 20.Conclusion: RGTAs are effective biological agents for the treatment of corneal epithelial defects following severe ocular surface chemical injuries.
