High intraocular pressure (IOP) can be categorized from a clinical point of view into pseudo-elevated IOP and true elevated IOP. Pseudo-elevated intraocular pressure is mostly due to non-disease factors, while true elevated intraocular pressure is related to disease factors. The management of elevated intraocular pressure varies according to the cause. 1. Pseudo-elevated intraocular pressure (IOP): Excessive use of the eyes, such as long hours of work, study, computer, cell phone, etc., can cause a transient increase in intraocular pressure, resulting in soreness, swelling and discomfort in the eyes. This situation can be dealt with at home. Through massage around the eyes, rest with eyes closed, gaze away and relax to relieve. 2. Genuine elevated intraocular pressure: elevated intraocular pressure caused by glaucoma can be treated with intraocular pressure-lowering medications such as latanoprost; if the medications are not effective, laser surgery is needed to lower the intraocular pressure. If there is a tumor in the eye, the growth of the tumor will also squeeze the eye tissues and cause the IOP to rise. In this case, the tumor should be actively treated first, including surgery and radiation therapy. Patients who suspect that they have high intraocular pressure, which cannot be relieved after proper rest and adjustment, should go to the hospital for examination and treatment in time, so as to avoid delaying the condition. Drugs should be used under the guidance of a doctor, do not self-medicate.
