RESUMO
Ocular burns can have three origins: chemical (by acid or alkaline agents), luminous (by ultraviolet radiation) or thermal. We report the cases of eight patients with ocular burns (3 thermal and 5 chemical). Of these, one patient had a grade 2 burn according to the Dua classification, two had grade 3 damage and one had grade 4. One patient had grade 3 damage in the right eye and grade 4 in the left eye. Anterior segment optical coherence tomography (AS-OCT) was performed in two patients, showing corneal de-epithelialization, corneal thickening and a hyper-reflective line in the posterior stroma. All patients received medical treatment with topical antibiotics, topical corticosteroids, cycloplegics and wetting agents. Five patients had outpatient treatment with clinical improvement. Three patients were hospitalized, one of whom received an amniotic membrane graft (AMG), one had an AMG followed by a transfixing keratoplasty (TK), and the other is scheduled for a TK. Ocular burns are associated with significant functional risk, warranting prompt and effective management.
