Glaucoma is an eye disease generally due to a low intake of vitamins and essential nutrients. Any disorder creates high pressure in your eyes which leads to this disease. The disease affects optic nerves adversely and leads to blindness and other optical issues.
Keep reading to know about what Glaucoma is and its effects.
Glaucoma is referred to as a group of eye diseases that are harmful to optical nerves and hamper vision. When the drainage angle (the area through which the eye fluid or aqueous humour drains out) does not function properly, it causes high pressure inside the eyes and leads to Glaucoma. This disease comes genetically and occurs typically in old age.
Though Glaucoma does not cause any pain, it may lead to vision loss. However, it is curable if diagnosed at the right time, and the vision can also be returned.
It is the basic form of the disease that is caused due to blockage of optic nerves. The process is slow and involves no pain. Further, it will not affect your vision at the early stage. People with weak optic nerves are prone to this type of Glaucoma. However, a regular eye examination can reveal this disease's symptoms.
People with iris close to the drainage angles in their eyes face this type of Glaucoma. Here, the iris blocks the drainage channels; thus, the eyes get an immediate shock of high pressure. In this situation, patients can face pain and other complications. Therefore, it is recommended to call a doctor as soon as possible.
Normal-tension Glaucoma happens if you face low pressure inside your eyes due to low fluid production. Though the range remains low to normal, it develops signs of Glaucoma, such as damage to optic nerves and blind spots.
Secondary Glaucoma happens due to injury, medication, accidents, eye inflammation etc. This type also attacks optic nerves adversely and results in vision loss.
When pigmentary granules from the Iris break off with eye fluid that is Aqueous Humour and blocks the drainage channel, it is called Pigmentary Glaucoma. Heavy jogging can sometimes cause the deposition of pigments.
An outer layer from your eye's lens sometimes peels off and sets in between the angle of the Cornea and Iris. Therefore, it blocks the eye's drainage channels and causes Glaucoma. This type of Glaucoma is known for causing severe eye pressure.
Abnormal growth of new blood vessels on the Iris and over the drainage canals causes blockage and high pressure of fluid inside your eyes. Therefore, it harms Optic nerves and causes Glaucoma. This condition occurs due to other health issues such as Diabetes.
The main reason for this disease is eye injury that damages the Optic nerves. It may show symptoms in the early stage or comes after many years.
Generally, this type of eye disorder happens due to inflammation from different drugs. Irritation near the Iris of the eye canal causes channel blockage and leads to Glaucoma.
The leading cause of this disease is damage to optic nerves. When these optic nerves get blocked, a fluid called aqueous humour can not flow properly. Therefore it causes extra pressure inside your eyes and harms optic nerves, leading to Glaucoma.
However, there are some other causes of Glaucoma, which are:
Open-angle Glaucoma does not show any symptoms in its early stage, but the other types can show some noticeable symptoms. These are as follows:
Though this disease hardly shows any symptoms in the first stage, however, the comprehensive risk factors that can mark its presence are:
You should visit an eye specialist if you notice any early signs of Glaucoma, such as blurred vision or eye pain. However, if you do not notice any, you should also go for a routine eye check-up to avoid harmful circumstances. The diagnosis process is as follows:
There are several treatments available for treating this disease. These are:
This disease is curable in an early stage with proper medication. Usually, eye drops are enough to lower eye pressure, which further reduces the chance of this disease. Some eye drops reduce the flow of Aqueous Humour. Thus, the eye pressure decreases.
However, medication may not always suit every patient as it has side effects. In addition, they can react by merging with other regular medicines. Therefore, you should consult an eye expert before starting or stopping any medicine for Glaucoma.
The last method to treat this disease is surgery which involves 3 effective processes. These are:
The preventive measures for Glaucoma are:
Therefore, hope you now have a comprehensive idea of what Glaucoma is and how to prevent and treat it properly. The discussion reveals that this disease is not very harmful in its early stage. However, proper diagnosis can reduce further adversity. Hence, you should consult an experienced eye specialist to know more about this disease.
