Intraocular pressure (IOP) of 35mmHg is considered high IOP because IOP of 35mmHg has exceeded the upper limit of the normal IOP value of 10~21mmHg. IOP is the pressure exerted by the contents of the eye (aqueous humor, vitreous humor, lens) on the wall of the eye, and the range of normal IOP is between 10~21mmHg. The intraocular pressure of 35mmHg is already higher than the upper limit of normal intraocular pressure of 21mmHg, so it belongs to high intraocular pressure, but whether it is abnormal or not needs further examination. Patients with intraocular pressure of 35mmHg need to go to regular hospitals for further detailed examination, such as visual acuity, angle of the room, visual field and other examinations, to clarify whether it is simply high intraocular pressure or glaucoma. If it is high intraocular pressure, observation is sufficient and no medication is needed for the time being. If it is glaucoma, it is necessary to follow the doctor’s advice to use intraocular pressure-lowering drugs such as brinzolamide eye drops or surgical treatment, such as trabeculectomy. It is recommended that patients with abnormal intraocular pressure consult a doctor for evaluation of their condition and treatment as prescribed by the doctor.
