Perforation of the eyeball is one of the common ocular traumas involving injury to the wall of the eyeball, and depending on the location of the perforation, it can be categorized into corneal perforation injuries, scleral perforation injuries, and corneoscleral perforation injuries spanning the corneoscleral rim. Corneal perforation injuries are most common clinically because the cornea is exposed in front. Perforation of the eyeball requires CT examination of the eye and orbital region, intraocular pressure examination, fundoscopy, ultrasound of the eyeball and orbital region to assist in the diagnosis of the disease. The diagnostic criteria for eyeball perforation are described in detail below. 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 the 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 remain unchanged or become deeper. Both eyes should be compared and carefully distinguished. 3. Intraocular pressure (IOP): Due to perforation of the wall of the eyeball, the aqueous humor spills out of the eye, and the contents of the eye are dislodged, and the IOP is obviously lowered. Be careful when checking the intraocular pressure, so as not to aggravate the dislodgment of ocular contents. Perforation of the eyeball is equivalent to the breakage of the true eye in Chinese medicine. It is often combined with intraocular foreign body; there is eye pain, photophobia and tearing, and sharp decrease in visual acuity. Its severity depends on the perforation site, size and treatment. Perforation wounds are an important pathway for the invasion of evil poisons, and some of them may affect the side of the healthy eye, i.e. sympathetic ophthalmia as described in Western medicine.
