eye piercing
Introduction
Introduction The perforation of the eyeball is seen in the perforation of the eyeball, and the sharp or foreign body perforates the wall of the eyeball, which is called the perforation of the eyeball. According to the different parts of the perforation, it can be divided into corneal perforation injury, scleral perforation injury and corneoscleral perforation injury across the limbus. Corneal perforation is the most common clinically due to corneal exposure. It is most common to strike the eye with the debris splashed by the metal. The consequences and functional recovery of the perforation injury are mainly determined by the severity of the injury, followed by whether the treatment is timely, appropriate, and whether there are serious complications.

1. Vision: The degree of vision loss varies depending on the location of the perforation. For example, simple perforation in the peripheral part of the cornea, the wound is small, and the visual acuity can be unaffected.
2. Anterior chamber: If the perforation is in the cornea or cornea, the aqueous humor is constantly overflowing, the front is shallow, and the wound is larger. The iris tissue can be pulled out and invaded in the wound, and the pupil is deformed; for example, the perforation is in the sclera, and the eye content is The wound is prolapsed and the depth of the anterior chamber can be unchanged or deepened. Should be carefully compared with both eyes.
3. Intraocular pressure: due to the perforation of the eye wall, the aqueous humor overflows, the eye content is released, and the intraocular pressure is significantly reduced. Be careful when checking the intraocular pressure, so as not to aggravate the release of the contents of the eye.
Diagnosis
Differential diagnosis
Eyeball perforation confusing symptoms:
1. Eye blunt contusion: equivalent to Chinese medicine impact injury. Clinical manifestations vary, such as swelling of the eyelids, blood stasis, laceration, subconjunctival hemorrhage or corneal opacity, dilated pupils, reduced or not round, turbid aqueous humor, lens dislocation, vitreous hemorrhage, fundus hemorrhage, edema, exudation, The omentum is detached.
2. Eyeball perforation injury: equivalent to the true eye damage of Chinese medicine. Often combined with foreign bodies in the eye; and there are eye pain, photophobia, tears, and sharp drop in vision. The severity depends on the location, size and treatment of the perforation. Piercing the wound is an important way to invade the sinister poison, and some will affect the healthy eye, that is, the sympathetic ophthalmia of Western medicine.
3. Chemical injury: Chemical substances enter the eye, that is, see eye pain, photophobia, tears, conjunctival congestion and edema, even gray necrosis, corneal opacity, especially alkaline burns are more serious. In the later stage, corneal total vasospasm can be formed, which seriously affects vision or blindness.
4. Electro-optic ophthalmia: refers to a certain incubation period (6-8 hours) after exposure to ultraviolet rays, and there is burning pain in the sand, strong fear of light and tears, and the eyelids are extremely difficult.
