Glaucoma is an eye disease in which the intraocular pressure rises abnormally beyond the maximum tolerated by the eye, resulting in damage to the optic nerve, visual field defects, and eventually vision loss or even blindness. Myopia is one of the high-risk factors for glaucoma. Clinically, myopia and glaucoma often coexist. According to statistics, myopic eye pressure above 1000 degrees is higher than normal by 30%, while above 2000 degrees is higher than normal by 50%, and myopic eye accounts for 60% of glaucoma patients among young people. Why is the pressure in highly myopic eyes easily increased? There is a fluid in the eye called atrial fluid, which is continuously produced and discharged, and its production and discharge are in balance, so the intraocular pressure is maintained at a certain normal level, and the normal intraocular pressure is 11-21 mmHg. The atrial fluid is discharged through numerous micropores (filter curtains) at the anterior chamber angle and then reaches the veins. In highly myopic eyes, these micropores become fewer in number, smaller in size, and less open, resulting in increased resistance to atrial flow. When less severe, although the IOP is still normal, its functional reserve is poorer than normal, and once there is inflammation and other changes in the eye or when hormonal eye drops are ordered, it is poorly tolerated and can easily cause an increase in IOP. Myopia combined with glaucoma has the following clinical characteristics: 1. high incidence, especially in highly myopic eyes, it is reported that the incidence of glaucoma in highly myopic eyes is 6-10 times higher than that in normal people 2. often no obvious symptoms, especially in the early stage, it is easy to be ignored, and once found, it is already late, 3. signs are not typical, the symptoms of the two diseases are easily confused, and the changes in glaucoma are mistaken for changes in myopia, resulting in missed diagnosis and delayed treatment, 4. 4. High myopia and glaucoma affect each other, as elevated intraocular pressure can cause the eye to grow longer and accelerate the development of myopia, and the development of myopia can be easily damaged by glaucoma, forming a vicious circle. Therefore, patients with myopia, especially those with high myopia, should be aware of the occurrence of glaucoma and should undergo regular comprehensive examinations at hospitals with diagnostic facilities.
