眼烧伤（Eye burn） brief introduction When the eye is exposed to high fever or chemicals, eye hazard is rapidly reflected and closed to prevent burns. But extreme temperatures can still burn the eyeball. The severity and pain of burns. Chemical burns can be caused by certain irritating substances entering the eye. Even less irritating substances can cause significant eye pain and injury. Ocular burn Region: eye Department of Ophthalmology: burn department, Department of Ophthalmology Symptoms and signs: eye pain, hearing loss, eye movement disorders, abnormal pupillary sensation, dehydration Pathogeny Among the causes of eye burns, thermal and chemical burns are the most common. Other sources include radiation burns. 1., chemical eye burns: by sulfuric acid, nitric acid, hydrochloric acid and other acidic substances or potassium hydroxide, sodium hydroxide, ammonia, lime and other basic substances accidentally hurt the eye. 2. heat source eye burns: high temperature substances such as fire, boiling water, hot oil, steam, etc., and direct contact with the eye tissue, causing burns, mostly with facial or systemic skin burns combined. 3. radiation burns: radiation injury including the electromagnetic spectrum of various radiation damage, such as microwave, infrared, visible light, ultraviolet ray, X-ray and R neutron or proton beam can also cause this kind of damage. (1) infrared damage: glass processing and high temperature environment can produce a large number of infrared eye damage is mainly the thermal effect of short wave infrared (wavelength 800-200mm), can be caused by cataract and iris crystal absorption (formerly known as glassblower cataract). (2): visible light injury can cause macular burns, such as the naked eye observation eclipse caused by eclipse retinopathy youth and emmetropia rare, and high myopia is rare, light damage and seasonal weather related properties of the eclipse of the retina (photic damage). The mechanical, thermal, and photochemical effects
