Repeated abnormal intraocular pressure (IOP) after an impact on the eye may be related to trauma-induced regression of the atrial angle, intraocular infection and inflammation, and accumulation of blood in the anterior chamber. 1. Atrial angle regression: It is mainly caused by the separation of the ciliary body’s circular fibers from the longitudinal fibers due to the impact, at this time, the position of the iris may change and be deformed, which may cause recurrent abnormal intraocular pressure in severe cases. If the symptoms are severe, filtration surgery is usually recommended as soon as possible. 2. Inflammation of intraocular infection: After the eye is hit, there may be serious damage to the surface, and if daily care is not done properly, bacteria or other microorganisms may enter, which may cause inflammation and lead to recurrent abnormalities of intraocular pressure. Antibiotic drugs such as levofloxacin eye drops can be used as prescribed by the doctor to prevent infection after the impact injury. 3. Hematochezia in the anterior chamber: After an eye injury, there may be hematochezia in the anterior chamber, which, if not eliminated, may cause recurrent abnormal intraocular pressure. Generally high intraocular pressure can be relieved with the absorption of blood in the anterior chamber. After the eye is hit, you should consult the doctor in time to avoid delaying the condition.
