persistent corneal epithelial defect as a complication of tetracaine abuse
نویسندگان
چکیده
purpose: to describe the clinical signs, diagnosis and treatment of toxic keratopathy in a patient who abused tetracaine drops. case report: a 32-year-old man was referred to the emergency ward of our center with persistent corneal epithelial defect associated with a ring infiltrate in the corneal stroma, without any history of ocular trauma or contact lens use. the patient was hospitalized and a thorough ocular examination was accomplished. a detailed history in our patient revealed topical anesthetic abuse keratitis. the topical anesthetic was deliberately taken from the pharmacy without a prescription. the hallmark of topical anesthetic abuse keratitis was a persistent corneal epithelial defect and a complete ring infiltration in the corneal stroma in our case. functional and anatomic results after appropriate treatment were not favorable in this case. conclusions: although topical anesthetic abuse keratitis is rare, it should be carefully explained to patients that although topical anesthetics numb the eye, more than a few drops can actually prevent healing and may lead to permanent damage. the unrestricted availability of topically applied ophthalmic anesthetics as over-the-counter medications in iran must be reevaluated.

متن کاملAmniotic membrane transplantation in the treatment of persistent epithelial defect on the corneal graft.
It has been shown that amniotic membrane transplantation (AMT) improves healing of the epithelium defects as it serves as a basement membrane for endothelial cells growth, prevents inflammatory cell infiltration and reduces apoptosis in keratocytes. Having in mind the healing properties of AM we investigated the efficacy of AMT in persistent epithelial defect (PED) on the corneal graft. 80 corn...
