Glaucoma refers to eye-related disorders that causes problem to optic nerve which sends signal to the brain. It is generally found in people above 40 years of age. But sometimes it can also be found in young adults and infants. It is very difficult to recognize if a person has Glaucoma or not at the initial stage, because it has very negligible or no symptom. But if someone has been suffering from Glaucoma, he/she can be diagonised and treated. Glaucoma treatment generally includes eye drops prescribed by the physicians, laser surgery and micro-surgery.
1. Eye drop treatment : These drops reduce the formation of fluid in the front of the eye or in some cases increase its outflow.These drops may also cause side effects.These side effects may include allergy, redness of the eyes, blurred vision, and irritated eyes. Some Glaucoma drugs can also affect the heart and lungs.
2. Laser surgery: Laser surgery slightly increases the outflow of the fluid from the eye or eliminates fluid blockage.Laser surgery for glaucoma includes trabeculoplasty in which a laser is used to open the trabecular meshwork drainage area. Another is iridotomy in which a tiny hole is made in the iris that allow the fluid to flow more freely. Third one is cyclophotocoagulation in which a laser beam is used to treat areas of the middle layer of the eye to reduce the production of fluid.
3. Micro-surgery: It is an operation which is called trabeculectomy. In this operation a new channel is created to drain the fluid which reduces intraocular pressure that causes glaucoma. Sometimes microsurgery fails and must be re-done. Sometimes, a glaucoma implant, a tube that helps to drain fluid from inside the eye, is the best option. Open-angle Glaucoma is generally treated with various combinations of eye drops, laser trabeculoplasty, and microsurgery. If a person is born with it then it is primarily treated with surgery, because the cause of the problem is a very distorted drainage system.
Glaucoma can not be prevented but it can be diagonised and treated under time. So, tegular check-up is necessary to know if a person is facing this problem, especially if he/she has family history of Glaucoma. Food items which are rich in vitamin A, like milk, carrot, tomato, green leafy vegetables and fruits, must be taken by Glaucoma patients.
Beware! I question everything and everybody.
