Penetrating eye injury

Introduction to eyeball penetrating injury Perforating wounds (perforating wounds) are cuts or stabs of objects with a favorable edge or tip, foreign matter debris entering the eyeball, and blunt injuries and eyeballs causing eyeball rupture. The double-punch through which the front part penetrates through the entire eyeball and is pierced from the back is called a penetrating wound (health wound), which is a kind of eyeball penetrating injury. The diagnosis of eyeball penetrating injury is summarized as follows: (1) history of trauma; (2) eyeball wound; (3) decreased intraocular pressure; (4) shallow anterior chamber; (5) iris perforation; (6) pupil deformation; (7) crystal turbidity; (8) vitreous injury channel; Retinal damage; (10) foreign body retention; (11) decreased vision. Some of the above may not be obvious or not, especially small penetrating injuries, and even all symptoms are not obvious. Therefore, for every patient with suspected eye trauma, the medical history must be inquired in detail, and the examination should be carried out in detail to avoid delay in diagnosis and delay treatment. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: retinal detachment headache

Cause of eyeball penetrating injury

A sharp object accidentally penetrates into the eye or a small fragment explodes into the eye at a high speed to cause an eyeball penetrating injury.

Eye penetrating injury prevention

Prevent cutting or stabbing of sharp edges or sharp objects. First-aid method: use sterile gauze for the eyes, or cover with a clean handkerchief. Do not apply pressure. The face can be cold-applied with an ice pack or a cold towel to help stop the blood. Avoid bumps to prevent aggravation. Reasonable dietary habits: Maintain a light diet.

Such as porridge, milk, soft rice, soy milk, eggs, lean meat, fresh vegetables and fruits rich in vitamins A, B, C.

Eyeball penetrating injury Complications retinal detachment headache

Post-traumatic endophthalmitis: Common infections include Pseudomonas aeruginosa, Staphylococcus, etc., rapid development, eye pain, severe headache, obvious irritation, severe visual loss, or even no light perception, high conjunctival edema, congestion, corneal opacity, Anterior fibrin inflammation or extreme pus, vitreous snowball-like opacity or abscess formation.

Sympathetic ophthalmia: First, the uveal inflammation of the injured eye (called induced eye) continues to retreat, and gradually worsens, KP appears, the pupillary margin may have small pearl-like gray-white nodules, after 2 weeks to 2 months of incubation, Another eye (called sympathetic eye), suddenly appeared similar to uveitis, visual acuity decreased sharply, yellow-white punctate oozing out of the fundus, mostly located in the peripheral part (called Dalen-Fuchs nodules), sympathetic ophthalmitis, long course, Repeated episodes, due to extensive destruction of the retinal pigment epithelium in the late stage, the entire fundus is a dark red tone, called the evening glow-like fundus. When the treatment is improper or the condition cannot be controlled, complications such as secondary glaucoma, retinal detachment, and eyeball atrophy may occur.

The diagnosis of eyeball penetrating injury is summarized as follows: (1) history of trauma; (2) eyeball wound; (3) decreased intraocular pressure; (4) shallow anterior chamber; (5) iris perforation; (6) pupil deformation; (7) crystal turbidity; (8) vitreous injury channel; Retinal damage; (10) foreign body retention; (11) decreased vision.
Some of the above may not be obvious or not, especially small penetrating injuries, and even all symptoms are not obvious. Therefore, for every patient with suspected eye trauma, the medical history must be inquired in detail, and the examination should be carried out in detail to avoid delay in diagnosis and delay treatment.

Eye penetrating injury inspection

According to the clinical diagnosis, you can do head CT to understand the trauma.

Diagnosis and differentiation of eyeball penetrating injury

diagnosis

Diagnosis can be performed based on clinical performance and laboratory tests.

Differential diagnosis

It is differentiated from eye trauma, eye burns, and eye burns. When the eye encounters high heat or chemicals, the eyelids quickly and reflexively close to avoid burns. However, extremely high temperatures can still cause eyeball burns. Chemical burns can be caused by certain irritating substances entering the eye. Ocular trauma is one of the main causes of blindness caused by unforgettable mechanical physical or chemical damage from the eyeball and its appendages.
