Swollen and bruised eyelids, difficulty opening eyes, when eyelid hematoma occurs, attention should be paid to the time of appearance, which appears immediately after the impact.

Outline

Eye injury is a common accident, the third leading cause of blindness after cataracts and glaucoma. Traumatic eye damage is often complicated, requiring a proper and timely management attitude to partially limit the serious consequences of trauma.

Circumstances arise

Eye injuries can arise in many different situations, the most common being accidents in life, accounting for about 70% of cases. Most of them are found in children and students. Domestic injuries include accidents in the family, at school, sports, and traffic accidents.

Eye injury due to occupational accidents accounts for about 25% of cases. Injuries in industrial production are often caused by metal fragments thrown from high-speed machines such as milling machines, lathes, grinders ... so there is often an internal foreign object. Injuries in agricultural production are often very serious due to bacterial infections, especially green pus bacillus because the trauma agents are the sickle, scythe, steel wire ... often contaminated with soil and animal manure.

Fire trauma accounts for only about 5% of cases, but the damage is often complex, sometimes with both eyes, the risk of infection is high and there are many combined damages to the system.

Classify

Two clinical scenes:

Eye injury.

The wound in the eye.

Eye injury

The causes of trauma are often large, head-on objects such as fists, soccer, tennis balls, badminton ... The impact force causes vibration and pushes the eyeballs toward the wall of the socket. Strong compression increases intraocular pressure causing partial or complete rupture of the iris legs and Zinn cords. Then the negative feedback continues to shock the eyeballs.
