Intraocular pressure 29 may not be glaucoma, but it is high intraocular pressure, and it is recommended to go to the hospital in time. In addition, a temporary increase in intraocular pressure can be caused by factors such as mood swings. Intraocular pressure (IOP) is the pressure exerted by the structures and substances inside the eyeball on the wall of the eyeball, and the normal range is between 10 and 21 mmHg. Excessive intraocular pressure can put greater pressure on the optic nerve, causing necrosis of the optic nerve and defects in the visual field. An intraocular pressure of 29 mmHg does not confirm glaucoma. To confirm the diagnosis of glaucoma, the visual field and optic nerve should be examined. In addition to glaucoma, there is also hypermetropia, which is a condition in which the intraocular pressure remains higher than normal after several measurements, but there is no damage to the optic nerve or visual field. Patients with hypermetropia should have their IOP checked regularly, and should go to the hospital promptly if they have visual field defects. Patients are also susceptible to elevated IOP when they have severe emotional fluctuations, and after rest, the IOP will decrease to normal levels.
