Eye burns, which are usually caused by chemicals such as acidic, alkaline and heat-related substances, are true medical emergencies. These substances can lead to potential permanent damage to the eyelids, cornea, ocular surface and intraocular tissues. In severe cases, eye burns may result in blindness. Currently, there is a lack of uniform and standardized guidelines for the diagnosis and treatment of eye burns. As a result, a considerable number of patients have a poor prognosis. Therefore, the Cornea Group of Chinese Ophthalmological Society has developed this consensus statement after thorough discussions, hoping to provide guiding opinions on the clinical diagnosis and treatment of eye burns.
