Particular circumstances of ocular alkali burns in Martinique (French West Indies) have been indentified in this study which established the seriousness of these burns and their social and sometimes legal consequences. The importance of prevention is emphasized. It would seem that minor ocular alkali burns do not require a treatment duration longer than 15 days. Finally, the clinical data reported in this study show that a delay of several minutes is required for the development of severe ocular alkali burns.
