Most of the orbital foreign bodies enter the orbit from the front between the eye and the orbital rim. The eye can be left without direct injury and most retain vision, while a few foreign bodies that fly at high speed can penetrate the eye and remain deep in the orbit. 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. Diagnosis of orbital foreign bodies: Orbital foreign bodies, common orbital foreign bodies include metal shrapnel, steam gun shells, or wood or bamboo fragments. There may be local swelling and pain. If combined with purulent infection, it can cause orbital cellulitis or fistula. Since most intraorbital metal foreign bodies are wrapped in soft tissues and there are fine nerves, blood vessels and muscles in the deep orbital area, it is not necessary to remove such foreign bodies from the deep orbital area. Vegetative foreign bodies can cause chronic purulent inflammation and should be removed completely as soon as possible. In the case of orbital foreign bodies, the accompanying symptoms are: Visual impairment: Visual impairment refers to a certain degree of impairment of visual function, resulting in diminished vision, loss of vision, etc. The types of visual impairment include reduced visual acuity and affected visual fields. Visual acuity is a more precise representation of the function of the form of vision, and is divided into central vision and peripheral vision. Central vision is obtained through the macular center, and peripheral vision refers to the function of the retina beyond the macula. Eye distention: Eye distention is one of the diagnostic bases for eye fatigue. Eye fatigue is also known as visual fatigue. Eye fatigue is mostly caused by excessive eyesight, emotional and mental disorders, liver, spleen and kidney deficiencies. The main manifestation of the disorder is the inability to see for a long time, and the main manifestation of the disorder is dizziness, headache and eye distension. Eye pain: Eye pain is also known as ophthalmoplegia, a manifestation of pain in the eyes. There are two causes of eye pain, one is due to external factors and the other is due to eye diseases. Eye pain due to trauma is felt as pain along with a foreign body sensation, and eye pain due to intraocular or orbital disease is mostly a deep, dull pain in or behind the eye. Ocular pain can be seen in keratitis, corneal ulcer, ocular trauma, glaucoma, sclerositis, orbital pseudotumor, etc.
