Glaucoma is a condition that is caused by the pressure inside the eye. There are two kinds of liquids or fluids in the eye. One is the aqueous humor, and the other is the vitreous humor.
In a normal eye, both these fluids have to be produced and drained out regularly in a cyclic fashion. It is when the ducts are blocked and the fluids are not draining, the problem occurs. The pressure builds up inside the eye, and leads to a condition called glaucoma. It can become dangerous when the pressure builds up too much.
Untreated pressure can damage the optic nerve, and also cause blindness. However, glaucoma has been a condition that is complicated to understand. Some people have built up fluids causing pressure in the eyes, but they do not suffer from glaucoma as there are no indications found. Some people have no pressure in their eyes and yet suffer from glaucoma. Researchers have not been able to find out why this occurs. What causes glaucoma exactly is still a difficult thing to identify.
Even hypertension, called the ocular hypertension, has become the top reasons for causing pressure behind the eyes. Glaucoma may be caused due to several conditions including local eye problems. The only treatment available for this condition is surgery. The fluid retention is removed through surgery. However, there is no guarantee that the condition may not recur again. Diabetes and glaucoma have found a strong link, and people with diabetes can easily avoid the condition by taking precautions.
