This type of sports injury is often encountered in kindergarten or school. Most common injuries include swollen eyelids, skin contusions, corneal epithelial scratches, conjunctival lacerations, hemorrhages in the anterior chamber of the eye, dilated pupils, dislocated lenses, retinal shock, hemorrhages in the fundus of the eye, etc., and fractures of the orbital wall if the force applied is too great. Don’t panic after eye injury, you can’t rub it with your hands or handkerchiefs or other objects, and can’t press it. It is recommended that you don’t wash it, because if there is a wound or corneal epithelium scratches, it will cause infections. You should go to the ophthalmology department of the hospital as soon as possible. Ball injuries can sometimes cause hemorrhage in the anterior chamber of the eye. If you have anterior chamber hemorrhage, you should keep quiet, keep your head elevated, take a semi-recumbent position, and keep both eyes bandaged and braked. If the eyelid swelling is obvious after the injury, ice or cold water can be applied externally to prevent the bruising from worsening.
