Perforation of the eyeball is most commonly seen in perforating injuries of the eyeball, where the wall of the eyeball is perforated by a sharp object or a foreign body, all of which are called perforating injuries of the eyeball. Depending on the location of the perforation, they can be categorized as corneal perforation injuries, scleral perforation injuries, and corneoscleral perforation injuries that cross the corneoscleral rim. Corneal perforation injuries are most common clinically because the cornea is exposed in front. The following is a description of the tests that need to be done for eye perforation. 1, vision Due to the different parts of the perforation, the degree of vision loss is also different. If the perforation is in the peripheral part of the cornea, the wound is small and the vision can be unaffected. If the perforation is in the cornea or corneosclera, the aqueous humor is constantly overflowing, and the anterior aspect becomes shallow; if the wound is large, the iris tissue may be dislodged and embedded in the wound, and the pupil is distorted; if the perforation is in the sclera, the contents of the eye will be dislodged to the wound, and the depth of the anterior chamber may be unchanged or deeper. Both eyes should be compared and carefully distinguished. 3, intraocular pressure Due to perforation of the wall of the eyeball, the aqueous humor spills out, the content of the eye is dislodged, and the intraocular pressure is obviously lowered. Be careful when checking the intraocular pressure so as not to aggravate the prolapse of ocular contents.
