The causes of high intraocular pressure may be physiological factors and pathological factors, physiological factors include drinking too much water, emotional excitement, etc., and pathological factors include glaucoma and ocular inflammation. 1. Physiological factors: Keeping inverted and lying posture for a long time will affect the normal outflow of aqueous humor, which will lead to the increase of intraocular pressure. In addition, excessive drinking water or emotional excitement at one time will increase the secretion of aqueous humor, which will lead to a rise in intraocular pressure, but it is generally a temporary rise in intraocular pressure. 2. Pathologic factors: Diseases can also lead to increased intraocular pressure, such as eye trauma, eye inflammation, glaucoma, etc., of which glaucoma is the most common cause of increased intraocular pressure. Glaucoma is the most common cause of rising intraocular pressure. Patients usually need medication or surgical treatment, and the intraocular pressure will not return to normal on its own. It is recommended that patients with elevated intraocular pressure seek medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
