ABSTRACT

PURPOSE: To report the ophthalmological signs, symptoms, and clinical management observed during an unprecedented outbreak of chemical ocular injuries related to cosmetic hair ointments in Brazil.
METHODS: This descriptive, cross-sectional study reviewed medical records of patients treated at the emergency center of Fundação Altino Ventura for chemical ocular trauma associated with cosmetic hair ointment use between February 2022 and February 2023. Records with incomplete medical information were excluded.
RESULTS: The study included 168 patients (95.2% [n=160] female), with a mean age of 30.8 ± 9.7 years. The most frequently reported symptoms at presentation were pain (167/168, 99.4%) and photophobia (92/168, 54.8%). Severe pain was reported by 137 patients (80%). Keratitis was present in 280 of 336 eyes (83.3%), conjunctival hyperemia in 256 eyes (76.4%), and corneal abrasions in 174 eyes (51.8%). A decrease in visual acuity (worse than 20/25) was documented in 18.5% (31/168) of cases. Lubricants, antibiotics, and re-epithelialization ointments were prescribed to 64.8% (109/168) of the patients. Topical corticosteroids and oral vitamin C were administered to 34% (57/168) and 1.2% (2/168) of patients, respectively. Followup visits were required in 19% (33/168) of cases.
CONCLUSION: The outbreak of chemical ocular injuries linked to cosmetic ointments used for braiding and hair modeling in Brazil was marked by intense ocular pain, conjunctival hyperemia, keratitis, and corneal abrasions. Most patients were treated with lubricants, antibiotics, and re-epithelialization ointments, although approximately one-fifth required followup care, and one-third received additional treatment with either topical corticosteroids and/or oral vitamin C.
