Topical anesthetic abuse is one of the causes of ring keratitis. Ring keratitis is easily overlooked because it can mimic acanthamoeba keratitis or other infectious keratitis. The outcome is often poor leading to persistent epithelial defects corneal scarring and perforations. Case presentation We report the clinical presentation diagnosis and treatment of a 65-year-old Caucasian man who worked as a health care worker with bilateral toxic keratopathy caused by topical anesthetic abuse. Nonpreserved amniotic membrane transplantation was performed for both eyes of the patient. Conclusion It is important to identify and treat patients who abuse topical anesthetics before permanent vision loss ensues. Nonpreserved amniotic membrane transplantation may be useful in relieving pain and improving corneal surface in anesthetic agent abusers. Introduction Corneal damage associated with abuse of topical anesthetics has been reported by various sources 1-3 . Topical anesthetic abuse is one of the causes of ring keratitis 2 . This rare clinic entity is easily overlooked because it can mimic acanthamoeba keratitis or other infectious keratitis.

A case of bilateral toxic keratopathy caused by topical anesthetic abuse that was treated with nonpreserved amniotic membrane transplantation NP-AMT has been reported. To the best of our knowledge this is the first report of NP-AMT use for the treatment of bilateral toxic .
