Primary open-angle glaucoma | Health Source

Primary open-angle glaucoma (POAG) is a chronic disease in which the internal pressure of the eye ? intraocular pressure ? too high.

The POAG root cause eye damage and, if left untreated, eventually blindness.

Among those who are at risk for POAG over 35, diabetics, people with a family history of the condition, short-sighted people, black people, and people with heart and blood pressure problems.

Because there are no symptoms until the damage occurred restored, regular pressure checks should be performed on all people over age 35, especially with the increased risk of disease.

POAG is diagnosed by testing the analysis of intraocular pressure, optic disc and visual field measurements.

It can be treated with eye drops, tablets, laser, or surgery and conventional, but lifestyle is also an important factor.

What primary open-angle glaucoma?

Primary open-angle glaucoma (POAG) is characterized by a gradual increase in pressure within the eye (intraocular pressure). This causes a slowly progressive loss of peripheral (side) vision, and if left untreated, loss of central vision late and eventually blindness. It is a chronic disease that usually affects both eyes.

What causes primary open angle glaucoma?

Changes to channel the flow of aqueous humor the eye (the fluid in the eye), resulting in increased pressure in the eye. This pressure causes slow damage of the optic nerve, which usually sends a ?picture? of all that we see in the brain. If either the venous blood flow, blood vessels can be protected from the influence of pressure, but if the blood flow is low, even normal eye pressure can damage the roots.

As the eyes of the root becomes damaged, the field of vision becomes less and less, until eventually the entire field of vision was destroyed and a blind eye.

Who is the main open-angle glaucoma and who is at risk?

It is the most common form of glaucoma. It can affect people at any age but is more common in people over the age of 40.

They are particularly at risk for POAG are diabetics, people with a family history of disease, short-sighted people, blacks, and those with a history of heart or blood pressure problems or migraines.

What are the symptoms and signs of primary open-angle glaucoma?

This disease does not show symptoms until very late in the disease when the damage has occurred. Slow loss of peripheral vision is often not obtained by the affected person.

Cupping of the optic disc, intraocular pressure and visual field defects are symptoms that may arise during the medical examination (see diagnosis below).

What is primary open-angle glaucoma diagnosed?

Because glaucoma may not cause any symptoms until the damage was restored, every routine eye exams ? and perfecting each physical examination ? in all adult patients should include checking the pressure inside the eye. It is called tonometry. Normal readings are not to lead glaucoma eye pressure varies varies according to the time and increased the pressure on early glaucoma may be intermittent.

In addition to checking the intraocular pressure, eye doctor or eye doctor check disk (part of the eye visible veins within the eye) to change characteristics. Optic disc may appear normal or show what is called ?cupping?, in which the center of pressure, indicating glaucoma. Visual field can be checked, and may reflect the nature of the defect around. If glaucoma is suspected, you should have a complete assessment and frequent follow-up examinations by an ophthalmologist (ophthalmologist) and detailed visual field examination.

Primary open-angle glaucoma can be prevented?

The disease itself can not be prevented. However, eye damage from the disease can be prevented if diagnosed early and treated properly. Therefore all those who are at increased risk for these diseases require regular eye examinations.

What is primary open-angle glaucoma treated?

Most people can treat with medication given eye drops. Each patient must be carefully assessed to determine the appropriate remedy.

Eyedrops are used:

Alpha agonists: eg. Brimonidine, Ephedrine.

Beta blockers: eg. Betaxolol, Levobunalol, Carteolole, Metipranol, timolol and others.

Inhibotors carbonic anhydrase: eg. Dorzolamide.

Cholinergic agonists: eg. Pilocarpine.

Prostaglandin agonists: eg. Latanoprost and more readily available in South Africa.

The combination of the above.

If eye drops failed to stop the development of glaucoma, the laser or conventional surgery, or oral medications (Acetazolamide) is used. Laser trabeculoplasty or filtering surgery improve water drainage and Acetazolamide may reduce the production of aqueous fluid. This reduces pressure in the eye and prevent further damage to the roots of optics and vision.

Regular physical exercise reduces the intraocular pressure and protect optic root, and therefore, the best way to treat the condition naturally. You also get the other health benefits of exercise. Low-salt diet potentially dangerous in the eyes of glaucoma. Therefore, the normal amount of salt in your diet is important for the health of your eyes.

What are the consequences of primary open-angle glaucoma?

Untreated, the condition leads to blindness.

Untreated, vision can be saved during the treatment continues for a lifetime.

When to call the doctor

If you have any risk factors for the disease, you should see a doctor or an eye doctor at least annually for glaucoma examination. If you have glaucoma, a condition should be managed by an ophthalmologist for the rest of your life.
