The causes of the incidence of the disease Glaucoma


Overview of Disease Glaucoma!
Diseases Glaucoma is an eye disease in the main nerve, called the optic nerve. Optic nerve receives implus and transmit nerve from the retina to the brain, where we convert the electrical signals as image. Glaucoma is characterized by progressive damage to the optic nerve that generally begins with a subtle loss of side vision (peripheral vision).
Glaucoma
If glaucoma is not diagnosed then can progress to loss of central vision and blindness. Glaucoma is usually, but not always, associated with high pressure in the eye (intraocular pressure). In general, high eye pressure leads to damage to the optic nerve (optic nerve). In some cases, glaucoma can occur in the normal eye pressure but no disturbance regulation of blood flow to the optic nerve.
Types of Glaucoma Disease

1. Primary Glaucoma
Occurs people who have glaucoma talent.

2. Secondary Glaucoma
Occurred after a preceding cause (eg, vascular disorders, and diabetes hipertense)

3. Chronic Glaucoma (slow)
There is pressure on the eyeball. There was no pain, but the visual field will be narrowed gradually.

4. Glaucoma Acute (sudden)
Corner pressures anterior chamber. Attacks cause pain and can cause permanent damage if not treated promptly.

5. Congenital Glaucoma
Ordinary occurs at birth or immediately after birth. Usually caused by a sewer system in the fluid inside the eye is not functioning properly. As a result, increased eye pressure continues and causes enlargement of the baby's eyes, watery eyes front and foggy and sensitive to light.

Why of Glaucoma
Glaucoma is caused by an increase in prisoners liquid aqueous humor outflow through the trabecular networks, Schlemm's canal, and the venous system episkleral. Trabecular pores can be clogged by any type of debris, blood, pus, or other material.

Under normal circumstances, this fluid is produced in the posterior chamber, through the pupil into the anterior chamber of the eye and then flows through a channel. If the fluid flow is interrupted, there will be an increase in pressure. Increased intraocular pressure will push the boundary between the optic nerve and the retina at the back of the eye.

As a result, the blood supply to the optic nerve is reduced so that the nerve cells die. Because the optic nerve in decline, it will form the blind spots in the visual field of the eye. The first hit is the edge of the visual field, followed by the central visual field. If left untreated, glaucoma can eventually lead to blindness.

Signs or Symptoms of Glaucoma
To find out if you are affected by glaucoma, you should know the least like any signs or symptoms of glaucoma in advance. Here are some signs or symptoms that usually occur when a person experiences glaucoma:
  • Severe eye pain,
  • Blurred vision,
  • Redness of the eye,
  • Eye pain accompanied by nausea and vomiting,
  • When looking at the lights you will see a rainbow and eyes hurt because of swelling of the eyes,
  • Vision problems occur unexpectedly due to lack of light.
In fact, sometimes people with glaucoma did not experience any symptoms or signs of anything but the acute level they could not see. Therefore glaucoma is also often referred to as the "Thief of Sight".
Glaucoma Disease Risk Factors

Glaucoma can affect anyone. Early detection and handling is the only way to avoid serious vision damage caused by glaucoma. For those who are at high risk are advised to check your eyes regularly since the age of 35 years. The following risk factors:
  • A history of glaucoma in the family,
  • High eye pressure,
  • Myopia (nearsightedness),
  • Diabetes (diabetes),
  • Hypertension (high blood pressure),
  • Migraine or narrowing of the blood vessels of the brain (poor circulation),
  • Accident / previous surgery on the eye,
  • Using steroids (cortisone) in the long term,
  • More than 45 years.
