Ocular trauma includes damage to which eye structures?

Ocular trauma is caused by mechanical, physical, and chemical factors that act directly on the eye, causing structural and functional damage to the eye. Ocular trauma can be divided into mechanical and non-mechanical depending on the causative factors of the trauma. Mechanical ocular trauma usually includes contusions, penetrating injuries, foreign body injuries, etc.; non-mechanical ocular trauma includes thermal burns, chemical injuries, radiation injuries and gas injuries, etc. The traumatic injuries can be divided into 3 categories: minor injuries include eyelid abrasions and bruises, subconjunctival hemorrhage, foreign bodies on the conjunctival and corneal surfaces, corneal epithelial abrasions, eyelid first-degree thermal burns, irritating gas injuries, and electrophthalmic uveitis; moderate injuries include eyelid and tear duct lacerations, eyelid second-degree thermal burns, bulbar conjunctival tears, and superficial corneal foreign bodies; severe injuries include extensive eyelid lacerations and defects, eyelid third-degree burns, penetrating eye injuries, intraorbital foreign bodies, blunt contusions with intraocular hemorrhage, chemical injuries to the eyelid of degree II or higher, radiation injuries, orbital bone fractures, etc. Ocular trauma is divided into two categories: mechanical and non-mechanical mechanical ocular trauma including non-perforating trauma (very mainly blunt contusion of the eye) perforating ocular trauma foreign body injuries these traumas can cause sympathetic ophthalmia blunt contusion of the eye injuries arising from blunt force trauma to the eye are commonly seen as follows: 1. subcutaneous bleeding and emphysema subcutaneous emphysema of the lid is a combination of blunt contusion of the eye and fracture of the medial wall of the orbit (often the septal sinus) gas in the septal sinus enters Subcutaneous petechial hemorrhage and emphysema are usually self-absorbing and should be prevented when accompanied by subcutaneous emphysema. 2, corneal epithelial exfoliation to prevent infection apply antibiotic ointment and cover the injured eye with a bandage. 3, anterior chamber hemorrhage is caused by iris or ciliary body hemorrhage can be secondary to glaucoma when the patient’s cause should be bed rest in a semi-sitting position so that the blood is deposited below the anterior chamber without obscuring the pupil appropriate application of hemostatic drugs secondary to glaucoma should be internalized to lower the intraocular pressure drugs if necessary anterior chamber puncture. 4, iris root disconnection and traumatic pupil dilatation disconnection range of small improvement is generally not dealt with Shunxin disconnection range of large should be performed surgical hours suture answers to restore the original position of the pupil due to trauma dilatation ambassador sphincter paralysis or tear is often not easy to this recovery. 5, vitreous hemorrhage ciliary body choroid or retinal hemorrhage caused by patients in the meal should be less active appropriate application of hemostatic drugs. 6, retinal concussion after injury retinal clouding edema grayish white can disappear on its own serious impact trauma can cause retinal rupture hole leading to retinal detachment need surgery know ashamed treatment. 7, traumatic cataract and lens dislocation can cause secondary glaucoma. 8, choroidal hemorrhage and rupture injury early rupture is often covered by hemorrhage hemorrhage absorption to reveal the rupture is gray-white fracture is bowed concave surface toward the optic papilla. 9, eye rupture injury serious blunt contusion can cause eye rupture before the eye is good in the corneoscleral rim of the eye is good in the posterior part of the eye is good around the optic nerve before the eye can often be surgically sutured by heart the posterior part of the eye is sutured to seek medical help difficult.
