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.

Detection and treatment of glaucoma
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.

Tips on Healing Glaucoma Naturally
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.

Diabetic retinopathy signs and treatments
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.
Acute and chronic forms of glaucoma
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.
Types of glaucoma and diagnosis
In the United States, more than a half of the 2.5 million glaucoma patients suffer from different degrees of vision loss. Resulted from internal eye pressure (IOP) built-up and optic nerve damage, glaucoma has been the second leading cause of blindness.
From the IOP accumulation and optic nerve damage to various degrees of vision loss, there are always no obvious symptoms so that glaucoma is often called the “silent thief of sight”. One exception may happen to acute angle-closure glaucoma, which bring blurry vision, halos, intense eye pain, nausea or vomiting.
Tonometers can measure your IOP either by resting a small probe or sending an air puff onto your eye’s surface. IOP above 30 mmHg indicates a problem of the amount of fluid in the eye and brings a much higher risk of developing glaucoma. Special eye drops are created to keep IOP low, which is a treatment for glaucoma.
Scanning laser polarimetry, optical coherence tomography and confocal scanning laser ophthalmoscopy can be used to monitor the progression of glaucoma by setting up baselines and detecting changes. Optic damage by glaucoma may bring blind spots, so that visual field tests can also be used to monitor glaucoma. And ophthalmoscope can be used to view your eye’s internal structures.
There are mainly two types of glaucoma: acute angle-closure glaucoma and chronic or primary open-angel glaucoma. Chronic glaucoma has no obvious symptoms during its process of decreasing your peripheral vision. The result is that you can only see objects straight ahead. Unlike primary open-angle glaucoma, another form of open-angle glaucoma has normal IOP level, which is called normal-tension glaucoma. This type of glaucoma has no other different features with primary open-angle glaucoma. Also called narrow angle glaucoma, angle-closure glaucoma brings unexpected symptoms such as eye pain, headaches, halos, red eye etc… These symptoms appear in certain periods.
Besides the above types of glaucoma, there are still other variations. Pigmentary glaucoma is caused by iris pigment deposits and clogs the draining angles. This form of glaucoma also has no clear symptoms. Secondary glaucoma is always associated with infection, inflammation or an enlarged cataract. Infants may be born with congenital glaucoma due to natural narrow angles. Parents should take good care of their babies’ eyes, in case of congenital glaucoma signs such as cloudy, white or hazy eye.
Eye drops with medication are used to control glaucoma by bringing down IOP. Careless use of these eye drops may bring higher risks of vision loss. Further treatments include glaucoma surgery, lasers and medications.
