Glaucoma is caused due to an increased pressure of the fluid within the eye. This causes atrophy of the retina and the optic nerve with serious vision repercussions. The optic nerve becomes damaged from high eye fluid pressure, and if this damage continues, glaucoma will cause the total loss of vision. It occurs when intraocular pressure increases; this happens when the fluid pressure in the eye's interior chamber rises.
Glaucoma mostly affects both eyes, but may be much serious to a particular eye.

CAUSES
The causes of glaucoma are mostly due to INHERITANCE. Glaucoma is mainly passed on from parents to offsprings.
Other important causes of glaucoma are:

* Blockage of the eye's blood vessels

* Chemical injury to the eye

* Inflammatory conditions of the eye
TYPES
There are mainly two types of glaucoma. They are:

* OPEN-ANGLE GLAUCOMA: This is the most common type of glaucoma. Here, the structure of the eye appears to be normal but the fluid within the eye does not flow properly through the trabecular meshwork, eye drain.

* ANGLE-CLOSURE GLAUCOMA: This type of glaucoma is usually less common but very chronic. Here, drainage usually appears to be poor, due to the angle between the Iris and the Cornea being too narrow.

SYMPTOMS
At first, there are usually very few or no symptoms, but later on the symptoms gradually appears.The symptoms include:

* The loss of side vision, which can go undetected until late in the disease

* Sudden eye pain

* Redness in the eye

* Blurred vision

* Headache

* Nausea or Vomitting.

PEOPLE AT RISK
Certain people are at the risk of having glaucoma.
* People over the AGE OF 40 are at a higher risk of having glaucoma..
* Also, people who have a family history of glaucoma also stands a chance of getting affected..
* Diabetes patients are also at the risk of having glaucoma.
* People having poor vision are also at that risk.
Any individual falling in the above groups i.e linked with any of the above risks, is adviced to consult an eye doctor for a complete diagnosis yearly or on regular basis. If the disease is detected at its earlier stage, it can be controlled.

TREATMENT
Glaucoma are usually treated with antibiotics like eye drop, and also laser surgery can be perfomed.
Glaucoma cannot be prevented, but if detected early in life, it can be controlled.
Diet also plays an important role as foods like Coffee, proteins, Trans-fatty acids aggravates glaucoma.
Other foods that tends to control it are ORANGE and Vitamin A and B1.
