Another View on Glaucoma
Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often linked with a buildup of pressure inside the eye. Glaucoma tends to be inherited and may not show up until later in life. The increased pressure, can damage the optic nerve, which transmits images to the brain. If damage to the optic nerve from high eye pressure continues, glaucoma will cause permanent loss of vision. Without treatment, glaucoma can cause total permanent blindness within a few years. Glaucoma usually occurs when pressure in your eye increases. This can happen when eye fluid isn't circulating normally in the front part of the eye.
Normally, this fluid, called aqueous humor, flows out of the eye through a mesh-like channel. If this channel becomes blocked, fluid builds up, causing glaucoma. The direct cause of this blockage is unknown, but doctors do know that it can be inherited, meaning it is passed from parents to children. Less common causes of glaucoma include a blunt or chemical injury to the eye, severe eye infection, blockage of blood vessels in the eye, inflammatory conditions of the eye, and occasionally eye surgery to correct another condition. Glaucoma usually occurs in both eyes, but it may involve each eye to a different extent.
There are two main types of glaucoma, open angle and closed angle glaucoma. The fluid in the eye flows through an area between the iris and cornea, where it escapes via the trabecular meshwork (angle refers to this area). Fluid drains into s set of tubes, known as Schlemm's canal, from which they flow into the blood system. Closed Angle Glaucoma can come on suddenly, and the patient commonly experiences pain and rapid vision loss. Fortunately, the symptoms of pain and discomfort make the sufferer seek medical help, resulting in prompt treatment which usually prevents any permanent damage from occurring.
