Do not let it to steel your vision




Glaucoma is an eye disease caused by increased pressure inside the eyeball, when detected early enough through regular eye exams is easily treatable.

People who have their eyes regularly checked with either an optometrist or an ophthalmologist as part of a routine eye exam will be as part of the exam tested for a serious eye disease known as glaucoma. This is a relatively silent disease that can strike at anytime, and when symptoms are finally detected, for some it may be too late.

We can sub-categorize glaucoma as--acute and chronic. Thankfully the acute form is rare, but nonetheless when it does occur, immediate treatment should be sought to prevent permanent loss of vision.

Basically, glaucoma is a condition where pressures will build up within the eyeball. It is like a sink that is filling up with water, and with the drain closed. If you place some kind of a flexible cover over the sink, the cover will start to bulge outward. Similarly, this is what happens inside the eyeball, and if left untreated can lead to impaired vision or permanent blindness.

The eye normally discharges this buildup of fluid through a network of tissues called a “drainage angle.” Problems begin when proper drainage within the eyeball does not take place through this area called the “drainage angle,” which is located between the iris and the cornea. As long as this “drainage angle” does not function correctly, the pressures will continue to build in the eyeball, and this in turn will reduce the blood flow to the retina and the optic nerve.

Without nourishment from the blood, fibers of the optic nerve can die. The person’s vision starts to dim, and if left further untreated this can and most often does lead to permanent blindness.

This condition is easily treated through the use of a laser, i.e. by creating a small opening in the iris to relieve the pressure, or even creating a new opening that will successfully correct this potentially debilitating disease.

Some of the early symptoms to watch out for are blurred vision, loss of peripheral vision, teary eyes, and headaches. In the more serious forms there can be sudden eye pain, again blurred vision, halos of lights, even nausea and vomiting.

Other treatments involved in this disease are injections and medications that will help alleviate the pressure behind the eyeball.

Thankfully, glaucoma is treatable, especially the acute form and even if that is present, proper immediate treatment will restore normal vision. In chronic glaucoma, early detection is the only known cure at this time.

If a person is taking certain medications such as for asthma, irritable bowel syndrome, or an antidepressant, they should regularly scheduled an eye exam as certain medication can bring on symptoms of this disease.

By having the eyes examined every three to five years, especially for persons over 40 will provide an early enough detection if glaucoma is indeed present.

What are the symptoms of glaucoma? What are the causes?

You cannot see or feel the pressure in your eye because, in its early stages, glaucoma shows no symptoms. In fact, up to 40% of your optic nerve can be damaged before you notice any vision loss.

It was once thought that high eye pressure was the main cause of glaucoma. Although high eye pressure is a risk factor, it is now known that other factors are involved.

Are there any different types of Glaucoma?

There are many different types of glaucoma, but we have listed only the most common ones below.

Open-angle glaucoma (primary open-angle glaucoma — POAG) is the most common form of glaucoma and the one most often associated with aging. It occurs when fluid from the eye cannot pass through the eye’s filtration area to drain. This buildup causes increased eye pressure, which may damage the optic nerve.

Angle-closure glaucoma (acute glaucoma) is a condition in which fluid at the front of the eye can’t leave because a part of the iris is blocking the angle through which it would flow. This type of glaucoma may result in a sudden increase in eye pressure, which comes with severe pain and nausea, and is considered a medical emergency.

Congenital glaucoma is a condition that exists when children are born with defects in the angle of their eyes. These defects keep the fluid in the eye from draining, causing eye pressure to increase.

Secondary glaucoma can develop following an eye injury or trauma to the eye. This type of glaucoma may develop because of problems from eye surgeries, cataracts, certain eye tumors, or eye trauma.

Pigmentary glaucoma occurs when small parts of pigment from the iris (the colored part of the eye) break off and clog the angle where fluid flows out of the eye. This type of glaucoma is a form of secondary open-angle glaucoma.

Normal-tension glaucoma (NTG) occurs when there is unexpected optic nerve damage in people who have normal eye pressure. This damage comes with the same narrowed side vision as open-angle glaucoma, and is treated in the same way.

Does high eye pressure cause damage to vision?

High eye pressure occurs when drainage channels in the eye become clogged, causing the pressure in the eye to increase. This pressure can damage the optic nerve. The optic nerve is like a cable. It has more than a million fibers that send messages about what we see from the eye to the brain. If left untreated, damage increases, and may eventually lead to blindness.

What are the normal eye pressure ranges?

The normal range of eye pressure is from 8 to 21 mm Hg, but there are a number of factors, for instance, the thickness of your cornea, that can affect this reading. Different people may have different sensitivity to the level of pressure. Some eyes can tolerate a higher pressure than others, but as a general rule, the lower your eye pressure, the lower your risk is of developing glaucoma.

What is the difference between high eye pressure and glaucoma?

Glaucoma and high eye pressure are not the same thing, but are closely related. High eye pressure occurs when drainage channels in the eye become clogged, causing the pressure in the eye to increase. This increased pressure puts pressure on the optic nerve, which can cause damage to it. Glaucoma is the general term used to describe damage to the optic nerve caused by high eye pressure.

How fast does the condition typically progress? Is it reversible?

Glaucoma progresses very differently for each individual, depending on the type of glaucoma, how early it is diagnosed, and if it is being treated. Normally, this damage progresses over a number of years. However, in some cases, it has been known to progress much more quickly.

Unfortunately, damage caused by glaucoma is irreversible. For this reason, it is important to see your eye doctor on a regular basis. Through early detection, you and your doctor can help preserve your vision.

How can I decrease my eye pressure? What are the treatment options?

There are many treatment options for lowering eye pressure, including eyedrops, pills, laser surgery, eye operations, or a combination of methods..

Does medication prevent the condition from worsening?

Yes. Medicated eyedrops focus on lowering eye pressure because studies have suggested that, for most people, lowering eye pressure slows the advancement of glaucoma.

What can I expect in the years to come? Will I go blind?

Although there is no cure for glaucoma at this time, studies suggest, for most people, lowering eye pressure slows the advance of glaucoma. For this reason, glaucoma treatments focus on lowering eye pressure. Glaucoma can be managed and controlled with medication and/or surgery, and you can go about your life as you did before.

The good news is that glaucoma sufferers rarely lose their sight, as long as the proper precautions are taken. If glaucoma is left untreated, damage increases, which may eventually lead to blindness. You should have your eyes examined regularly (check with your eye doctor about how often) and make sure you take your medicine as your doctor has instructed.

Does diet, exercise, or change in behaviors help?

There is no medical research that shows that any type of food or diet affects glaucoma, however, some studies suggest that exercise may be beneficial. Exercise lowers eye pressure and improves blood flow to the entire body, including the optic nerve. It is important to remember that exercise in which the head is lower than the heart for a long period may increase eye pressure. Those exercises should be avoided.

In addition, it is always a good idea to avoid smoking or second-hand smoke. Tobacco can irritate glaucoma and may even worsen the disease.
