Introduction

Our vision is a divine gift. With it, we can witness the beauty of nature. For a person with blurry or no vision at all, the world would be dark and non-existent. Even life could be meaningless. We must do our best to protect this gift of God and look after it for it must stay healthy. There are many diseases that hamper the function of our eyes and can cause a loss of vision. One of such disease is Glaucoma.

Glaucoma is the eye disease in which the optic nerve is severely damaged. Our eyes have a lens that focuses on objects when light falls on them. The images are carried to the brain through a nerve called the optic nerve. The optic nerve in this disease gets damaged beyond repair and is unable to transmit optical signals to the brain. As a result of which, a person loses his vision and this loss might be permanent. Anyone can contract this disease but people who are above 60 years of age are more vulnerable to contract this disease.
This disease is caused by the pressure buildup inside the eye around the optic nerve. The
pressure damages the optic nerve and subsequently reduces its ability to carry optical signals to the brain. As the pressure around the optic nerve gets worse so does the disease.

It can cause permanent loss of vision to total blindness. The early symptoms of this disease are not prominent and the symptoms remain mild until the disease gets worse. That is why it is prescribed that people should get their eyes tested regularly.

Symptoms of Glaucoma
There is a fluid inside our eyes that usually flows out through natural openings. If by any chance the natural openings of our eyes get blocked the fluid couldn’t move out, it starts building pressure around the optic nerve. There are several causes of the blockage of natural channels.
Blocked blood vessels inside the eyes, any chemical injury to the eye, a severe eye infection, or inflammation might end up building the fluid pressure which compromises the function of the optic nerve.
This disease has two variants. One of which is called Open or Chronic Angle Glaucoma. During this condition, a patient would not feel any significant symptoms until he has lost a significant percentage of his vision. The first sign which appears in this condition is the loss of side vision which the doctors would refer to as the loss of peripheral vision. Until the loss of peripheral vision is significant and the patient goes to consult a doctor, the disease has already taken hold and had caused significant damage.

The other variant of this disease is called the Acute-, Closed-, or Narrow-Angled Glaucoma. This is associated with severe eye pain. People suffer from throbbing eye pain. Eye-redness and headaches are common. Other symptoms include blurry or foggy vision, dilated pupils, vomiting, and nausea. When these symptoms appear, it is strongly recommended to see a doctor immediately. The optic nerve is very sensitive and the damage starts within a few hours. This condition, in severe cases, might end up with permanently dilated pupils, a reduced vision or, in most critical cases, a complete loss of vision.

Prevention of Glaucoma
Prevention of this disease means taking certain measures so as to detect it before its
occurrence. It is important as it helps in the treatment of the disease, in preventing vision loss or slowing down the spread of the disease.
Getting your eyes tested is the best prevention strategy to stay away from contracting this
disease. Scheduling visits with the specialists would help detect any strange happening in your eye function. The disease is common in people who are 40 years of age or above. People above 60 are the most vulnerable age group. Therefore it is suggested that these people should visit a doctor at least once a year.
Glaucoma tends to run in families. The families in which there have been cases of Glaucoma should be more focused and should regularly visit the specialist. This could be their own chance to tackle this disease.
Certain exercises are helpful which reduces eye pressure. Consult a specialist to know which exercises would suit your condition.
Glaucoma medication is helpful in reducing eye pressure. These eye drops, if are prescribed by a doctor, must be taken regularly.

Treatment or Management of Glaucoma
Open or Chronic Angle Glaucoma appears with symptoms that include the loss of peripheral vision. The cure of Acute Angle Glaucoma includes reducing the fluid levels inside the eye or lowering the fluid production. Medication or eye surgery both can accomplish this task of
reducing levels of eye liquids.
Closed or Acute Angle Glaucoma is different from the Open or Chronic Glaucoma. The Acute Glaucoma happens suddenly and with intense pain. In this condition, laser therapy works best. The Iris of the eye is punctured to let the liquids flow out and to reduce the pressure of the optic nerve.

Conclusion
Glaucoma is a disease which one must try to stay away from. Its sudden occurrence is
dangerous. The organ of the body which it affects, the eye, is very critical as it is one of the five human senses. Once affected, the condition could be irreversible and the result can be complete blindness.
Hence, doing everything to prevent this disease from happening is the best strategy. The
prevention includes getting your eyes tested. It is a common observation that the patients of this disease are the elderly with over 60 years of age. These most vulnerable group should plan yearly schedules with their eye specialists. Since the incidence of this is sudden and most of the cases remain asymptomatic most of the time before the incidence of the disease, therefore, if any of the signs associated with this disease occur, it must not be taken lightly and immediate medical attention should be sought. The optic nerve is very sensitive and it could get damaged permanently in a matter of hours. People should take care of the hygiene of their eyes. We must protect this special gift of nature.
