Eye foreign body injury

Foreign body injuries of the eye are relatively common, and can be divided into two types of metal foreign bodies and non-metal foreign bodies according to the nature of the foreign body. Most foreign objects are iron and steel magnetic metal foreign objects, and there are also non-magnetic metal foreign objects such as copper and lead. Non-metallic foreign bodies include glass, crushed stone, plant-based (such as linden, wood) and animal-based (such as wool, thorn) foreign bodies. The damage caused by different types of foreign bodies in different parts of the eye and their treatment are different.
