In the eye, there is a fluid called atrial fluid, which is produced and discharged continuously, and the amount of production and discharge is balanced, so that the intraocular pressure is maintained at a certain normal level, and the atrial fluid is discharged through the schlemm’s canal at the anterior chamber angle and then reaches the vein. In highly myopic eyes, the number of schlemm’s ducts becomes smaller, the aperture becomes smaller, and the ducts are less open, resulting in increased resistance to atrial flow. When it is less severe, although the IOP is still normal, but its functional reserve is worse than normal, once the eye has inflammation and other changes or hormonal eye drops, it is poorly tolerated and can easily cause the IOP to rise. When the resistance of atrial water flow is serious to a certain degree, there is no triggering cause for the IOP to rise and the optic nerve is damaged, which is glaucoma. 1, what are the early symptoms of myopia combined with glaucoma (1) emotional excitement or stay in the dark for too long (such as watching movies, television or working in a dark room), there will be eye distension, headache, blurred vision, as if there is a layer of cloud in front of the eyes, which is the early symptoms of closed angle glaucoma. After repeatedly appearing many times, it may suddenly enter the acute grand mal period. (2) Headache occurs when you usually drink more water at one time. This is because drinking water quickly and in large amounts can make the blood dilute causing a decrease in osmotic pressure, and the atrial fluid entering the eye will increase, thus causing an increase in intraocular pressure. Patients often develop eye swelling and headache 15 to 30 minutes after drinking water. (3) Presbyopia appears before the age of 40, especially in women, and presbyopia changes rapidly, requiring frequent replacement of glasses. This may be related to the loss of eye regulation and is directly proportional to the degree of early glaucoma lesions. (4) Visual acuity gradually decreases, and the visual acuity corrected by optometry is less than 1.0. Especially for highly myopic people, they often have headache and eye distension even after wearing moderate glasses. As the sclera of high myopia becomes longer, the elasticity decreases significantly, so when high eye pressure appears, the self-conscious symptoms are not obvious or asymptomatic, and the patient is easy to neglect, while the vision is quietly lost, and the doctor is often easy to miss the diagnosis. (5) After waking up in the morning, it is more difficult to read books and newspapers, and it is easy to have soreness at the root of the nose and swelling of the orbital forehead. Because the IOP of normal people has a pattern of diurnal fluctuations, it is generally higher in the morning and lower at night. Glaucoma patients have a greater fluctuation of IOP over 24 hours, so the IOP is higher in the morning and symptoms will appear. (6) A colorful halo appears at night when looking at lights, as if a rainbow appears in the sky after a rain, which is medically called rainbow vision. This is due to a rise in intraocular pressure and corneal refractive changes caused by corneal edema. This is a very special symptom at the onset of glaucoma and should be taken seriously. 2, myopia combined with glaucoma how to treat glaucoma is one of the main causes of blindness in China, and the damage to visual function caused by glaucoma is irreversible and the consequences are extremely serious. Generally speaking, glaucoma cannot be prevented, but with early detection and reasonable treatment, most patients can maintain useful visual function throughout their lives. Therefore, the prevention of glaucoma must emphasize early detection, early diagnosis and early treatment. The aim of treatment is mainly to lower eye pressure, reduce eye tissue damage and protect visual function. If you have myopia, you need to get an eye exam and glasses, and you also need to check the fundus to see if there are some fundus lesions. 3, myopia combined with glaucoma can be cured glaucoma is due to poor water circulation gradually blocked, resulting in the symptoms of increased intraocular pressure, the main thing is to control the intraocular pressure, to regularly review, if the intraocular pressure continues to rise will cause headaches, eye swelling, eye pain and other symptoms, when the intraocular pressure exceeds the eye tissue (mainly for the optic nerve) can withstand the limit, it will cause optic nerve atrophy, resulting in visual field loss, and optic nerve Once the damage is irrecoverable, only the existing vision can be preserved, so if you have glaucoma must go to a regular hospital for examination, determine the cause, point to lower eye pressure eye drops, laser treatment and surgery, control eye pressure, and regular review. If you have myopia, especially high myopia, i.e. more than 600 degrees, you should also go to the hospital regularly every year to check your eye fundus. If you do not feel well, follow up with your doctor.
