Ocular trauma is not uncommon in our daily life, and most of them occur instantly. On-site self-help and rescue are the key to restoring eyesight later. Eye trauma is divided into two categories, one is mechanical eye trauma, that is, caused by sharp or blunt objects, mainly eye penetration injuries, eye rupture injuries and intraocular foreign body injuries; the other category is non-mechanical eye trauma, that is, caused by chemicals, high temperature and radiation, mainly alkali, acid, thermal burns. Penetrating eye injuries are mostly characterized by hot tears and blurred vision, while ruptured eye injuries are mostly characterized by bleeding and tearing and loss of vision. Therefore, when the eye injury is confirmed, the first thing is to protect the injured eye, but do not rub the eye again, even a small pressure, can lead to intraocular tissue and eye contents from the wound out of the eye, aggravating the damage to the eye. Next, cover the injured eye with your hand to determine if the injured eye can see clearly, and quickly refer to a hospital with ophthalmology. Mechanical eye injuries rely heavily on surgical repair by an ophthalmologist, while non-mechanical eye trauma focuses more on self-help, and successful self-help at the scene can reduce eye damage. After a chemical splash into the eye, you must immediately flush with water for more than 15 minutes; if there is no clean water source at the scene, use pond water, ditch water, well water can also be used, do not look for clean water near and far. It is important to know that high concentrations of acid can make the surface of the eye protein coagulation denaturation, while high concentrations of alkali has tissue permeability, can make deeper intraocular tissue damage. Therefore, after the injury, the concentration can be reduced by rinsing with a large amount of water to minimize the damage to the eye tissue. Do not use alkali to neutralize acid or acid to neutralize alkali when rescuing at the scene, as any concentration of industrial alkali or acid can aggravate the damage to the eye. Thermal burns are mainly flame injuries and contact burns. In the case of flame injury, the damage to the eye is mostly minor because of the eye closure function of the eyelid which plays a role in protecting the eye. Contact thermal burns are mostly caused by boiling water, boiling oil in daily life or molten iron or aluminum water splashed into the eye in the workplace. The former damage is slight, the latter in addition to high temperature to the eye injury, often due to foreign body embedded, chemical reaction and aggravate the injury. Therefore, in addition to on-site flushing with water, should be immediately transferred to the hospital by the ophthalmologist treatment.
