Most of them are caused by accidents. Common orbital foreign bodies include metal shrapnel, gunshot, or wood or bamboo fragments. There may be local swelling and pain. The foreign body can be removed in stages, that is, the exposed shallow foreign body is discharged first, and the foreign body buried in the deep layer of the cornea can be left untreated. If the foreign body is large and has partially penetrated the cornea into the anterior chamber, foreign body extraction should be performed in the operating room, and the corneal wound should be sutured if necessary. Most of the orbital foreign bodies enter the orbit from the front between the eye and the orbital rim, and the eye can be directly uninjured and most of them retain their vision. Injury-causing objects are mainly metallic foreign bodies such as lead bullets and steel, but a few are non-metallic such as glass and plants. Orbital pseudotumor: Pseudotumor ofthe orbit is a nonspecific chronic proliferative inflammatory disease, named because of its true symptoms. In the aura stage, there is a paroxysmal pain in the orbital distribution area, accompanied by tearing, conjunctival edema and protrusion of the eyeball. The disease is self-limiting, and after a certain stage of development, the masses become fibrotic and the lesions become stable. Ocular trauma: Ocular trauma is the direct action of mechanical, physical and chemical factors on the eye, causing structural and functional damage to the eye. According to the causative factors of trauma, it can be divided into mechanical and non-mechanical. Mechanical ocular trauma usually includes contusions, penetrating injuries, foreign body injuries, etc. Non-mechanical ocular trauma includes thermal burns, chemical injuries, radiation injuries, and toxic gas injuries, etc.
