Glaucoma
The eyes of every person has pressure just like the blood. So, when the Intraocular pressure increases to dangerous levels. It damages the optic nerve. This leads to decreased peripheral vision and finally blindness.
Glaucoma is similar to the ocular hypertension but with accompanying optic nerve damage and the vision loss. Glaucoma is regarded as the leading cause of blindness, everywhere in the world. Even if people with glaucoma do not become blind, vision is severally lessened in them.
Signs and symptoms of glaucoma
There are two major types of Glaucoma. One is Chronic glaucoma. Also known as Primary open angle glaucoma. The other one is Acute glaucoma and it is also known as acute closed angle glaucoma.
The Chronic glaucoma is also referred to as silent thief of sight. It is because in this case there is no warning sign or there is no hint that anything wrong is happening. Most of the people with Chronic glaucoma don’t know that they have it.
Glaucoma gradually reduces the peripheral vision but by the time people notices it, the permanent damage has already occurred.
If the person’s Intra ocular Pressure remains high, then the destruction can progress until tunnel vision develops and the person will only be able to see the objects that are straight ahead.
On the other hand, Acute angle closure glaucoma produces sudden symptoms such as eye pain, headaches, dilated pupils, vision loss, red eyes, nausea and vomiting. These signs may last return again for another round. Each attack takes with it the part of the field of vision.
Other signs include blurred vision and difficulty adapting to darkness. The chronic narrow angle glaucoma is often symptom less, until vision loss occurs.
It is very difficult to spot signs for congenital glaucoma because the children are to young to understand. Congenital glaucoma occurs more in boys than girls. Pigmentary glaucoma generally shows no symptoms at all. Person may notice some pain and blurry vision after exercise.
