Three forms of glaucoma

People with healthy eyes have clear liquid which flows in and out of the anterior chamber of the eye. During this process, the eye tissues get normal “metabolism” and nourishment. There are known a lot of eye problems or diseases affecting different parts of the eye. In particular, the eye problem called glaucoma just involves an abnormality in the anterior chamber. People with glaucoma have blocked liquid flow in the eye, which causes a pressure buildup in the eye. This condition is exactly named as glaucoma that may ultimately lead to visual loss or total blindness. Glaucoma is actually one of the most common eye diseases in the world.

 

In general, there are different forms of glaucoma. Open angle glaucoma is the more common type among all cases. The canals in these patients’ eye get blocked and then the fluid flow stops gradually. Another form is called angel closure glaucoma, which is caused by complete blockage of the canal. This form of glaucoma is more serious that it even restricts the immediate flow of the liquid in the eye. And angle closure glaucoma is also more urgent that there is always accompanied a rapid rise in the eye pressure. A third form of glaucoma is the normal tension glaucoma, which involves no blockage of the eye canals and no buildup of eye pressure, just as its name reflects. However, this group of patients is supposed to suffer from damage to the optic nerve, which in turn also causes visual loss.

 

Unfortunately, most glaucoma patients realize this condition even when they have noticed visual loss. There is nearly no obvious symptom of glaucoma. In order to detect glaucoma as early as possible, individuals should pay enough attention to various abnormal visual and non-visual conditions, such as eye pain, headache, nausea, vomiting, and seeing halos around lights and so on. Once there is a detected glaucoma of the angle closure form, the commonest solution is to surgically remove a part of the iris, facilitating the flow of the liquid in the eyes.

Glaucoma is an eye disease that involves high press in the eyes. This condition can gradually damage one’s vision and even lead to permanent vision loss. Until now, most doctors prescribe glaucoma medicines for treatment, either eye drops or oral medications. This is the commonest way to control glaucoma. In detail, these medicines can effectively control eye pressure at a low level. At the side of patients, medicines are believed to be the safest solution. Glaucoma patients have to maintain these medicines, in case of the buildup of pressure in the eyes. However, medicines used to control glaucoma are always associated with some side effects on the other hand. Some of those side effects are unnoticeable while others are significant.

With the basic knowledge of glaucoma itself, there is still another solution to this disease. In the eye, there is a clear fluid that flows through the passages. Excessive eye pressure will be caused if these passages get blocked which leads to fluid buildup in the eye. This pressure buildup in the eye will finally cause glaucoma, potentially damaging the optic nerve. In general, there are two types of glaucoma: primary open angle and acute angle-closed.

Another treatment for glaucoma is laser surgery. During such a laser surgery for glaucoma, the surgeon will make holes and use them to shrink the clogged areas in the eye. The obvious purpose is to decrease the abnormally high eye pressure by draining the fluid in the eye. In detail, the surgeon will use a tiny but powerful light beam to make such holes. Since glaucoma can affect only one eye, glaucoma laser surgery may treat a sole eye.

Glaucoma laser surgery can be performed in a doctor’s office or in a clinic. In some cases, eye grittiness may occur. Another possible complication is swelling eye or eyes. Light sensitivity and blurry vision are also potential. It is fortunate that these complications are temporary that they will go away in several days. During the healing process, eye drops or oral medications are sometimes needed.

As a special eye disease, glaucoma usually develops slowly and unnoticeably. But this condition can damage the eye seriously and even lead to blindness. The normal circulation of watery fluid in the eye is essential for eye health. Healthy eyes allow eye fluid to enter and exit with ease. The reason of glaucoma is that the exit route for the fluid becomes blocked. As a result, pressure in the eye will increase. Without early detection and treatment, such an increased eye pressure would damage the optic nerve, which is closely associated with visual loss and blindness.

Currently, most eye doctors will prescribe eye drops for the control of eye pressure. Controlling or even lowering the increased eye pressure is actually the only thing that can be done. Of course, there are surgical ways to restore normal exit route for eye fluid. It is less known that there are still natural cures for glaucoma. Called Ayurveda, the ancient Indian natural health system is really an effective means of treating glaucoma in a natural way. Many aspects associated with daily life are involved.

According to Ayurveda, glaucoma patients should consume foods rich in vitamins and minerals, which are beneficial to eye health. Those beneficial nutrients include copper, zinc, vitamin A, B, C and E, and selenium. And recommended foods contain peppers, broccoli, citrus fruit, Brussels sprouts, guavas, kale, parsley and strawberries.

In addition, glaucoma patients are advised to get as much exposure to natural sunlight as possible, get as much as exercise each day as possible and mediate each day for at least 20 minutes. Another two common tips are included in Ayurveda. One is avoiding eye strain that regular breaks are needed during computer work, reading or driving. The other one is to get regular massages. Moreover, Ayurveda encourages people to limit caffeine and alcohol intake. Another extraordinary technique suggested by Ayurveda is to make a tea out of punarnava which is an Indian herb.

Once the glaucoma occurs, the damage on the optic nerves is irreversible. Though this eye problem can be treated, at later stage it is much hard to cure. Therefore, early examination is essential and it can be much easily cured once detected earlier.

Glaucoma is a mixed name of several similar eye problems that can lead to damage onto optic nerves by causing pressure in the eyes. Therefore, reducing such pressure is the key to cure this problem. When glaucoma happens, the pressure will become greater and greater.

With the development in medical technologies, more and more means can be used to treat this problem at very high success rate. Eye drops, eye surgery and medication are three of the commonest methods to tackle it.

Some particular eye drops can be used to reduce the pressure in the eyes. And facts have proved this method is very effective. How do eye drops help reduce the pressure? They can be used to reduce the fluid and speed up the drain in the eyes. Also those materials in the drops can also cure the problem.

Taking some medication is also a very important method. However, some complications may appear with this method. Eye surgery is the last resort. As for eye surgery, both traditional surgery and laser are very effective.

All those methods are just used to reduce the pressures in the eyes.

Glaucoma can be easily cured if detected at early stage. Thus, people should pay more attention to their eye health. Taking regular eye test and examination is essential and very important to maintain eye health. Keep in mind that glaucoma can lead to blindness if not detected early.

There are misconceptions among people who believe that one eye problems may aggravates any of other ones, for example, macular degeneration will aggravate glaucoma, or cataracts will aggravate macular degeneration. The fact is that macular degeneration is independent, and it is not tend to relate to some other conditions. In order to let you know they are unrelated, let’s have a view of each eye condition respectively.

Macular degeneration is always referred as age-related macular degeneration. It is a medical condition which usually affects the elders that result in a loss of vision in the center of the visual field because of damage to the retina.

A cataract is a clouding that develops in the crystalline lens of the eye. It is related to aging, which is very common in older people. Although both macular degeneration and cataract are related to aging, they are totally two different types of eye condition. The former is something affecting the retina or the macula while the latter is not, and a cataract, unlike macular degeneration, can be cured by removing or replacing by new lenses.

Glaucoma is a disease that affects the optic nerve and involves loss of retinal ganglion cells in a characteristic pattern and it is usually caused by high pressure. In a closed and fluid-filled system, if there are too much fluid in eyes, eyes will suffer from increasing pressure. Glaucoma can be a very serious eye condition, if not treated in time, a risk of complete loss of eyesight can be caused. As a matter of fact, glaucoma is fairly easy to be treated at its early stage.

Diabetic retinopathy is damage to the retina caused by complications of diabetes mellitus, which can eventually lead to blindness. It is a leading cause of blindness in American adults. Patients with diabetic retinopathy suffer from vessels bleeding or constricting, causing retinal detachment. This eye condition is usually treated by laser in the early stage. Some patients may even need focal laser surgery more than once to control the leaking fluid. Diabetic retinopathy is not related to macular degeneration, but has an influence on glaucoma and cataracts.

How to Prevent Glaucoma?

Our eyes are greatly ignored, though they are very important organs for our human beings. Generally, receiving eye examinations is very effective to detect some potential eye problems. But most of us have failed to do this. Therefore, many eye diseases become worsened when they are diagnosed.

Most of us seldom pay any attention to our eyes till they become sick. However, those problems can always not be treated easily when detected, though we go to visit eye doctors.

For example, the damage caused by glaucoma is not reversible and sufferers may become blind. But if it can be detected at its early stage and treated properly, suffers’ vision can be saved. In a word, prevention is much more effective than cure and receiving regular eye examinations is essential.

We can always enjoy the brightness of good vision even when we get aged if we can take care of our eyes. Receiving Regular eye examination is one of the best preventive methods. It is a bad habit to neglect eye care and visit the eye doctor until the problems get worsened.

In most cases, some symptoms can tell the existence of particular eye diseases. However, some disease will show no such symptoms. For example, sufferers of glaucoma can seldom detect any symptom until their vision gets lost completely.

If those diseases can be detected at early stage, they can be cured successfully. And examination is one of the best to detect any potential diseases. Of course, physical examinations are also needed if we want to maintain good vision.

Glaucoma involves the death of optic nerve fibers, caused by a lack of blood nutrition. The blood flow to the optic nerve connects the back of the eye to the brain. Some people want to know how they can prevent the development of glaucoma. Actually there is no scientific answer. Doctors often recommend taking certain drugs and nutritional agents to improve optic nerve nutrition. Smoking, alcohol abuse, unhealthy diet and obesity should be avoided.

Glaucoma can be detected at very early stages through a detailed optic nerve analysis using a test which measures nerve fiber thickness. The test can be done within a few seconds. This test is quite important in diagnosing glaucoma, because there are no clear signs of common glaucoma. Cataract and glaucoma are independent that glaucoma neither affect the result of cataract surgery nor can benefit from it.

Normal eye pressure is between 12 and 21mm Hg. High eye pressure does not lead to glaucoma at 100%, but it should be closely monitored. Those people with only high eye pressure are usually referred as ocular hypertensives.

Treatments for glaucoma include some medications, which may cause systemic side effects. Most good anti-glaucoma medications are effective in controlling eye pressure at minimal dosages. However, some of these medications get absorbed into the blood stream and impact other organs. Patients should be clear aware of potentially harmful side effects.

Glaucoma is one of the serious eye problems which can cause eye blindness. Increased eye pressure is a sign of glaucoma. Eye surgeries and eye drops may commonly be suggested to release the high ocular pressure in the eye. However, it is really ironical that the side effects of surgeries and eye drops would also lead to ultimate blindness.

According to Dr. Leslie Salov’s book “Secrets for Better Vision”, most glaucoma patients have very stressful and busy lives, most of whom are highly intelligent professionals. Dr. Salov believes that in order to improve eye health you should improve your entire health simultaneously, because every apparatus in your body can affect each other, and eyes are only a small part of your whole body. Simply speaking, in order to heal your eyes you must heal your body first, including physiology, biology, chemistry, philosophy and even spirituality.

Dr. Salov had recommended several methods to treat glaucoma. Through visualization you can control your body by your mind in order to heal itself. When you thinking good images in your mind, it can relax the muscles of your eye’s canal of Schlemm in which watery substance is collected, so that extra fluid can be excreted and the eye pressure can be relieved. Visualization has the similar function with eye drops, when it doesn’t have long-term side effects, for instance pieces of iris falling off, causing blockage. It is important that you use visualization with dedication and consistency, so that you can get the maximum benefits.

Meditation is a condition of thinking of nothing. It is another way to removes your stresses and worries after a day’s working. Because stress can lead to chemical changes in your body, decreasing blood flow and oxygen level.

Through deep and slow breathing you can deep clean your body and mind, and also improve your vision health.

A no-meat diet is strongly recommended by Dr. Salov, because the antibiotics, chemical dyes, and growth hormones in meat can also destroy your eye health. Without strong immunity, your eyes cannot utilize their natural healing ability.

Do them in your daily life, and you will see your glaucoma being healed naturally.

The American Academy of Ophthalmology has ever claimed that diabetic people are 25 times more likely to lose vision than normal individuals. However, there are less serious eye diseases that are also caused by diabetes, such as diabetic retinopathy and glaucoma. It is widely known that diabetic patients can not use and store sugar in a normal way, resulting in high blood sugar. This condition may damage the blood vessels and diabetic retinopathy will be caused. More seriously, scar tissue can be caused and leads to retinal detachment.

External symptoms of mild and advanced diabetic retinopathy include floaters and double vision. If you have difficulty in reading, there is probably macular edema from fluid built-up in the macula. Double vision is caused by the affection of eye nerves. For precise diagnosis, a test named fluorescein angiography will be carried out. Injected into the body, the dye will be tracked during its spread with blood flow. Evaluation of the result photos can determine the severity of diabetic retinopathy.

High blood-sugar in diabetic patients brings great risk and they do not know when diabetic retinopathy happens. Once diagnosed with diabetes, patients should take a dilated eye exam every year, in order to detect early diabetic retinopathy signs.

Diabetic retinopathy has different stages. An early form of diabetic retinopathy displays in fluid leakage and bleeding in the retina, which cause retina to swell and build up deposit. Experts define this form of diabetic retinopathy as non-proliferative retinopathy or background retinopathy. Also named proliferative retinopathy, a later stage of retinopathy is much more serious. New blood vessels begin to grow and break and bleed into the center of the eye, which may lead to blindness.

There are many ways to reduce the risk of developing diabetic retinopathy. Since the disease is mostly associated with diabetes, the most preventive way is to control your blood-sugar level. Regular exercises and healthy diet are important. For early detection, you should monitor your blood pressure regularly.

With early detection and treatment, diabetic retinopathy can be treated successfully at a percentage of 95. For normal diabetic retinopathy, a painless procedure named laser photocoagulation can be used to seal off leaking blood vessels and remove new vessel growth. Diabetic-caused cataracts can be cured with cataract surgery. Investigational treatments for diabetic retinopathy are reported to improve the patient’s vision and Lucentis and Avastin initially used for macular degeneration have been proved to be effective for diabetic retinopathy in stopping vision loss.

Most types of glaucoma are associated with narrow filtration angle, which hinders the outflow of eye fluids so that high IOP is caused. High IOP spikes and damages the optic nerve, which is responsible for images transmission from the eye to the brain. Optic nerve damage in turn causes vision loss.

There are mainly two types of angle-closure (closed-angle or narrow angle) glaucoma: acute angle-closure glaucoma and chronic forms of narrow-angle glaucoma. Acute angle-closure glaucoma occurs suddenly and has symptoms such as eye pain, headache, light halos, dilated pupils, and red eyes and so on. If the high IOP is not removed within hours, acute angle-closure glaucoma is likely to bring permanent vision loss. Once suffered from acute angle-closure, patients should contact an eye doctor immediately for emergency treatment. Chronic forms of narrow-angle glaucoma have no obvious symptoms and develop slowly. Both acute narrow-angle glaucoma and chronic angle-closure glaucoma cause at least part of peripheral vision loss.

Narrow-angle glaucoma always causes the abnormal positioning of the iris. And there are reasons for this situation. In a normal way, eye fluids produced by ciliary (behind the iris) flows easily through the pupil into the anterior chamber. Once the back of iris adheres to the lens, eye fluids can not pass through this pupillary channel. The blocked eye fluids will push the iris forward until it closes the drainage angle in the anterior chamber.

Another reason for narrow angle is iris plateau, which is caused by the extreme close distance between the iris and the ciliary body. In this case, the peripheral iris tissue bunches up in the filtration angel due to pupil dilation, so that the angle is narrowed.

Narrowed filtration angle is also associated with certain eye problems such as hyperopia. Hyperopic people are more likely to have shallow anterior chambers and narrow angles. A tumor behind the iris also increases the risk of angle-closure glaucoma. Normal aging always enlarges lens and increases pupil block. The filtration angle is likely to narrow as people age. There is also anatomical difference between races that Asians and Eskimos have narrower anterior chamber angles than whites. Angle-closure glaucoma does not occur equally between genders in some races.

Acute forms of glaucoma may bring vision loss if high IOP is not removed within several hours. The drainage angle may be narrowed by many factors such as dim lighting, eye drop administration, medications such as antihistamine drops and so on. All treatments for narrow-angle glaucoma aim at removing high IOP within a short period, such as systemic medications, topical glaucoma eye drops, and laser or non-laser glaucoma surgery.
