Intraocular pressure is the pressure between the three eye contents – vitreous humor, lens, and atrial fluid – interacting with each other and acting on the inner wall of the eye. High intraocular pressure is generally associated with eye fatigue, and there may also be pathological conditions such as high myopia, glaucoma, and cataracts, which can be improved by medication or surgical treatment. I. Common causes: 1. Eye fatigue: For patients who study or work for a long time, it is easier to make the eye muscles, blood vessels and nerves imbalanced, resulting in the atrial fluid can not be discharged normally, and then the intraocular pressure is too high; 2. High myopia: For patients with high myopia, the eye axis is relatively long, and the space in the anterior chamber of the eye is therefore smaller, so the pressure between the contents will increase, which will lead to the phenomenon of increased intraocular pressure; 3. 3. Glaucoma: In some patients with glaucoma, there is a reflux obstacle in the channel of the atrial fluid in the eye, which prevents the normal discharge of the atrial fluid, thus causing an increase in intraocular pressure; 4. Cataracts: Patients with cataracts may have a swollen lens that causes the iris to migrate, resulting in the closure of the anterior chamber angle, which leads to an increase in intraocular pressure; 5. Iridocyclitis: These patients have abnormalities in the ciliary body due to inflammation The posterior chamber pressure increases and pushes the iris to expand forward, occluding the anterior chamber angle and leading to elevated IOP; 6, ocular trauma: For patients with trabecular meshwork damage or blood accumulation in the anterior chamber due to falls, car accidents, etc., which causes abnormal atrial drainage, high IOP may occur; 7, other diseases: For patients with diabetes, cerebrovascular disease, cardiovascular disease, etc. For patients with diabetes, cerebrovascular disease, cardiovascular disease, the trabecular network in the anterior chamber of the eye is sclerotic, which leads to excessive atrial fluid, resulting in increased IOP. Second, the treatment: 1, eye massage: in the daily use of appropriate strength to massage the eyes, can play the eye muscles, nerve relaxation, eye fatigue, reduce the effectiveness of eye pressure; 2, drug treatment: can be under the guidance of doctors through local drops to lower eye pressure drops, oral diuretics, intravenous hypertonic solution, through the role of drugs to reduce intraocular pressure. In addition, for high IOP caused by iridocyclitis, anti-inflammatory treatment with hormones and non-steroidal anti-inflammatory drugs is required. 3. PNT non-invasive IOP-lowering surgery: The function of the uveosclera and trabecular meshwork can be improved by placing a therapeutic ring inside the eye to lower IOP. 4. Laser surgery: For some patients with high IOP, laser surgery such as diode ciliary photocoagulation can be performed to change the structure of the eye and relieve the high pressure in the eye; 5. Note: Patients with high IOP should take regular rest and avoid staying up late to avoid aggravating the high IOP situation.
