glaucoma(causes,signs,symptoms)

glaucoma
is a group of diseases, and the distribution of certain functions, usually including the Intraocular hypertension (IOP), optic nerve and damaged, as well as loss of peripheral vision.
The types of glaucoma:
Open-angle glaucoma
Angle closure glaucoma
Low tension glaucoma
Normal tension glaucoma
Congenital glaucoma
Secondary glaucoma
Pigmentary glaucoma
glaucoma caused by Steroid
Neovascular glaucoma
acute glaucoma as follows:
Closed angle glaucoma
Angle closure glaucoma
Narrow-angle glaucoma.
Factors that contribute to glaucoma
Although the reasons for the Blue have not been found, the study identified a number of factors that may increase the risk of glaucoma. These risk factors can be blue to work together to increase the risk further. The risk is higher in the blue waters of the following people: Afro-Americans over the age of 40 Every person over the age of 60 years, especially Mexican Americans Persons who have a family history of glaucoma People with diabetes. Comprehensive eye examination can reveal advanced more risk factors for glaucoma, such as: High eye pressure Proficiency in the cornea Abnormal neural anatomy.
Signs and symptoms of glaucoma
glaucoma is a group of diseases and the sharing of some features, including the high pressure within the eye (intraocular pressure), and the damage to the optic nerve, as well as the loss of peripheral (side) view. Blue symptoms may occur in one or both eyes. There are several types of glaucoma are open angle glaucoma is the most common. In this article we discuss the symptoms have been three forms of glaucoma: Open-angle glaucoma Angle closure glaucoma Congenital glaucoma.
Open angle glaucoma symptoms
Open-angle glaucoma, usually affects people over 50 years. First, people with open angle glaucoma or symptoms, and the state does not cause pain, and vision remains normal. However, as a condition for progress, and people with open angle glaucoma may notice a gradual removal of the side view (from the contrary, it was clear, but they object to this aspect may be missed). This may seem similar to the exploration of the tunnel. If left untreated, glaucoma may begin to cause loss of vision straight ahead and eventually lead to irreversible blindness. Point of view of the conclusion of glaucoma symptoms Primary angle closure glaucoma (also known as the blue water) is another form of glaucoma (see the blue water species). Contrast to the symptoms experienced open-angle glaucoma, and symptoms of this type begin suddenly and severely. In the angle closure glaucoma, the liquid in front of the eyes can not reach the corner, the left eye. Angle gets blocked by part of the midriff. People with this type of glaucoma have a sudden rise in eye pressure. As a result,
the signs and symptoms of angle closure glaucoma
include: Severe pain Nausea Red eye And clarity of vision.
Symptoms of congenital glaucoma
Usually affects the blue waters of the requirement that people over 35 years. However, it affects the children of congenital glaucoma. With this kind of children who are born with defects in the corners of the eye that slows down the natural drainage of fluid. Typically, these children have symptoms of blue and clear, such as:
Cloudy eyes
Sensitivity to light
Excessive gap.
