Ocular manifestations of transconjunctival heroin abuse: a case report of an unusual route of substance abuse.

PURPOSE: The purpose of this study was to present a patient with atypical corneoconjunctival lesions as a result of transconjunctival heroin abuse. METHODS: The authors conducted a prospective 8-month follow up of a 16-year-old girl who presented with bilateral atypical corneoconjunctival lesions. RESULTS: After a period of close observation, running diagnostic tests, and conservative treatment, the nature of the disease was suspected. Further discussion with the patient's family and her final confession revealed that she was using heroin through the conjunctiva. CONCLUSION: Substance abuse should be considered in the list of differential diagnoses in patients with an unusual presentation of ocular disease.
