PURPOSE This study aimed to describe the demographic and clinical characteristics of victims of fireworkrelated ocular trauma treated at the ophthalmologic emergency de partments of two reference centers in Pernambuco, Brazil, and to identify risk factors related to poor visual prognosis. METHODS We retrospectively evaluated the medical records of patients admitted in emergency departments with a report of firework-related trauma between January 2012 and December 2018. Data collected included patient's age, sex, place of origin, month and year of the accident, ocular structures affected, characteristics of the injuries, and type of treatment that patients received. For patients who were followed for >30 days, the final visual acuity and patient's origin were analyzed. RESULTS Three hundred and seventy eyes from 314 patients were included, of which 248 (79.0%) were male and 160 (51.0%) were from the metropolitan region of Recife. The mean patient age was 25.6 ± 18.8 years. In 56 (17.8%) patients, the ocular trauma was bilateral. A total of 152 (48.4%) cases occurred in June. The most affected sites were the eyelids in 91 (24.6%) eyes and ocular surface in 252 (68.1%). Surgical treatment was required in 87 (23.5%) eyes. After clinical and surgical management, 37 (10.0%) eyes presented final visual acuity of <20/400. Of these, 34 (91.9%) eyes were from patients from the countryside or from another state. Patients from the countryside presented higher risk of developing blindness after a firework trauma than those from the metropolitan area (odds ratio of 5.46). CONCLUSIONS Victims of firework-related ocular trauma were mostly male, from the metropolitan region of Pernambuco state and mainly pediatric patients or economically active. Those coming from the countryside and other states had higher risk of developing blindness.
