Glaucoma, second only to cataract, is the world’s second blinding eye disease and seriously threatens human visual health. What is glaucoma? Why does glaucoma occur? Which individuals are prone to glaucoma? How to find glaucoma? How should glaucoma be treated? I hope this article can briefly explain these problems. What is glaucoma? Glaucoma is a kind of disease that causes intraocular pressure to be too high due to various reasons and causes optic nerve damage. Generally speaking, it is the intraocular pressure that is too great and optic nerve is compressed, resulting in vision decline and visual field defect. Why does intraocular pressure rise? Maintenance of normal intraocular pressure, Mainly depends on the normal circulation of the liquid in the eyeball-aqueous humor. Aqueous humor comes from the ciliary body. It continuously produces aqueous humor every day, and slowly and steadily drains aqueous humor out of the eyeball to form circulation. Because the eyeball is a relatively closed structure, excessive aqueous humor production or poor aqueous humor drainage will lead to abnormal increase of internal pressure of the eyeball. Is high intraocular pressure necessarily glaucoma? The intraocular pressure of normal people is between 10 mmHg and 21 mmHg. If the intraocular pressure is higher than 21 mmHg, the possibility of glaucoma should be considered. However, it cannot be rigidly considered that if the intraocular pressure is higher than this value, the disease must be caused. Clinically, although the intraocular pressure of some patients has exceeded this value, there is no damage to optic nerve and visual field. Some patients have intraocular pressure within the normal range, But typical optic atrophy and visual field defects have occurred. Therefore, high intraocular pressure is not always glaucoma, and normal intraocular pressure cannot exclude glaucoma. Apart from intraocular pressure, doctors need to combine more examination results (visual field size, optic disc changes, angle opening and closing, etc.) to reach more accurate diagnostic conclusions. Glaucoma has what symptoms? Transient or repeated symptoms such as blurred vision, headache, eye pain, iridescence or vomiting accompanied by photophobia and lacrimation, Need to arouse vigilance. Abnormal increase of intraocular pressure will make the optic nerve compressed, and once the optic nerve is damaged, it is irreversible, vision will become worse and worse, vision shrinks, and even blindness. Therefore, if the above symptoms occur, be sure to diagnose and treat them early. Who does glaucoma prefer? Glaucoma has physical bias-glaucoma patients often have some specific personality characteristics, As melancholy and sentimental as Lin Daiyu and as dry as Zhang Fei, They are all the objects of glaucoma. So keep your mood stable, For preventing glaucoma or delaying glaucoma progression, It’s very helpful. Besides, Research shows that, Glaucoma has a certain genetic tendency. If the immediate family members have glaucoma, My chances of developing glaucoma will be greatly increased. Therefore, Children of glaucoma patients, It is best to screen for glaucoma regularly. Angle, intraocular pressure, visual field, Strive for early detection, early treatment, Keep glaucoma out. Medication and treatment of skilled glaucoma can be controlled and prevented. Through the above introduction, In fact, it can be inferred that Drugs for glaucoma should reduce the production of aqueous humor and promote the outflow of aqueous humor. In addition to drugs, At present, ophthalmic surgery is also very advanced. For example, through laser surgery, Preventive treatment can be achieved, It can also be done through trabeculectomy and other methods, Create a smooth [drainage channel], Let the outflow of aqueous humor become smooth again. However, Whether it’s medication or surgery, Patients should remember to check regularly, Monitor changes in intraocular pressure, visual field, etc. In addition to using drugs according to doctor’s advice, In addition to regular reviews, Glaucoma patients also need to pay attention to the following points in their daily life. Drink a small amount of water many times: To ensure normal water intake, But try to avoid drinking too much water at one time, Also avoid thirst before thinking about drinking water. Make sure the light is suitable: In the dark, our pupils get bigger, The angle of the chamber is narrow, thus blocking the outflow of aqueous humor. Therefore, stay in dark places as little as possible, avoid watching TV without turning on the light, reduce the number of times to watch movies in cinemas, and try to wear or not to wear sunglasses. Maintain a stable state of mind: the mood has a great influence on the disease, and try to keep a cheerful mood. Don’t be too excited, one excited, the pupil is dilated and has the possibility of inducing glaucoma.
