High intraocular pressure is usually associated with excessive eye use, endocrine, seasonal, blood pressure and other factors. Depending on the degree of high intraocular pressure, the symptoms and hazards of high intraocular pressure may also vary, mainly as follows: 1. At the same time, the high intraocular pressure may cause some degree of stimulation and damage to the optic nerve and surrounding cerebral nerves, causing edema of the cornea and eye tissue; 2. However, in patients with persistent and severe high intraocular pressure, symptoms such as narrowing of the visual field, nausea, vomiting, and iris vision may occur. Long-term or severe high intraocular pressure may lead to bleeding of the optic disc, loss of light perception, dilated pupils, optic nerve atrophy and other consequences, and in severe cases may even cause blindness. For patients with high myopia, glaucoma and other conditions, there is a possibility of high IOP. Therefore, for patients with high IOP themselves, it is recommended to go to the hospital for testing of IOP and fundus optic disc morphology, and if necessary, choose appropriate IOP-lowering drugs for treatment under the guidance of a doctor.
