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.

Signs of potential eye problems
Currently, there is a minority of people who have 20/20 vision for their entire lives. Most individuals will be bothered by certain eye problems at some point in life. As they begin to notice a vision declining, eyeglasses or contact lenses may be needed. Actually there are some warning signs of vision problems. They can indicate that one’s eyes are not quite right and a doctor’s visit should be arranged.
Blurred vision is one of the most common symptoms of various vision problems. As blurred vision always develops gradually over time, it may not be quite obvious at an early stage. In some cases, blurry vision occurs temporarily when there is a drastic change of light conditions in a room. Sudden blurriness can also result from eye rubbing, a cold or allergies.
Most people just ignore the blurry vision. However, prolonged blurriness requires a comprehensive eye exam from an eye doctor, especially the blurriness caused by none of the temporary reasons mentioned above. Persistent blurriness can be a symptom of an underlying eye problem.
Occasional eye pain around the eyes is usually normal and requires no serious concern, just like temporary blurry vision. Normal eye pain can be caused by too bright light, a headache, cold or sinus infection. In addition, eye pain can be a side effect of some medications. In similar, an eye pain that lasts for quite a few days could be a warning sign of eye problems, which requires a visit to the doctor.
Some hidden issues do not present initial symptoms until they have progressed. For example, glaucoma has no obvious signs at its early stage but it is the leading cause of blindness in US. Eye doctors can only use some tests to measure pressure within the eye before the disease progresses. Early treatment of glaucoma is quite essential.
It is necessary to have regular checkups with an eye doctor in order to find out underlying eye problems that have no initial symptoms.

Causes and remedy of scotoma
Scotoma can be caused by many factors, such as macular degeneration, strokes, traumatic brain injuries and disorders, which affect the retina or optic nerve. The most common form of blind spot is central scotoma, which is closely associated with macular degeneration.
Actually, macular degeneration is the most dangerous factor of scotoma, although other conditions listed above all affect the retina or the optic nerve. Central blind spot caused by macular degeneration is quite understandable. In the back of the retina, macula is responsible for central vision. However, macular degeneration can cause the photoreceptor cells or cone cells in the eye to die, which results in central blind spot.
In some cases, a central scotoma may enlarge as the macular degeneration progresses. Besides a spot in the central vision, a central scotoma has other symptoms such as need for more light, and contrast, difficulty perceiving certain colors and so on. These symptoms can be quite disabling and frustrating for some people. In serious cases, one’s independence can be affected by this retinal disease.
Most people suffering from central scotoma have to use their peripheral vision during most tasks. The formal term eccentric viewing is used to describe this special viewing way. A person using eccentric viewing always looks slightly away from an object in order to take use of his or her peripheral vision, rather than the defected central vision. In this way, the damaged cone cells do nothing but the rod cells can perform peripheral vision effectively.
In some instances, rod cells can be trained to perform some tasks that belong to cone cells in a person without central scotoma. These functions include detailed vision and color perception. But only with proper training, lots of practice as well as the appropriate visual aids can the rod cells acquire these functions. This process also requires the brain to learn new techniques and ways of seeing the world.

Symptoms and reasons of conjunctiva hemorrhages
It is always unnerving if there is a red spot that suddenly occurs on the white of the eye. Such a blood red eye can be quite disturbing. Many people think it is bleeding but it is usually not serious if there is no history of trauma or other health problems.
As a mucous membrane layer in the front of the eye, conjunctiva forms a loose covering over the sclera and extends under the eyelids. The conjunctiva is extremely sensitive to inflammation, because of the mast cells that release histamine when a person is exposed to an allergen.
Blood can accumulate in the space between the conjunctiva and the underlying sclera. The blood vessels in this part are small and subject to more movement and subsequent shearing forces. As a result, a vessel may break and bleed. The blood film is quite thin so that this blood spreads out in the space under the conjunctiva and appears to be a larger amount.
Coughing, vomiting, sneezing and straining for a bowel movement can all increase blood pressure temporarily, which may trigger a hemorrhage under the conjunctiva. Other potential triggers include ridding with a rapid acceleration and deceleration, merry go rounds and excessive eye rubbing and so on.
Conjunctiva hemorrhages usually undergo color changes over weeks and then resolve. They are painless and never cause vision loss. However, any bleeding on the eye deserves a thorough eye examination, in order to rule out potential serious eye problems. For instance, trauma can lead to an unknown eye perforation that may result in blindness without proper treatment.
The risk of conjunctiva hemorrhages can be increased by many factors. Those diseases include high blood pressure, arteriosclerosis, some types of blood cancers, diabetes and HIV. These drugs contain blood thinner, aspirin, ibuprofen and even birth control pills. Some systemic diseases are also possible contributors to hemorrhages, such as flu, measles, malaria as well as rare viruses.
The conjunctiva tissue is very active in the eyes own immune system. It keeps mucous on the eye surface and allows the eyelid to resurface the cornea as well as prevent dry eyes. People should receive routine eye check ups to keep it healthy.

Types and prevention of diabetic retinopathy
Diabetic retinopathy patients always suffer swelling and blood leakage in retinal blood vessels. The disease is often caused by fluctuating blood sugar levels and long-term diabetes. Juvenile onset (type one) diabetes requires more frequently regular evaluation than adults onset (type 2) diabetes. Most forms of diabetes can last 10 years in the early stage without causing diabetic retinopathy.
According to its reasons, diabetic retinopathy can to some degree be prevented by blood sugar control and high blood pressure control. However, even well-controlled diabetes may develop into diabetic retinopathy. Diabetic retinopathy at early stages only cause blurry vision or no symptom at all, while advanced diabetic retinopathy is always accompanied by cloudy vision, blind spots or floaters.
Based on changes in the retina, diabetic retinopathy is generally classified into non-proliferative and proliferative types. As the early stage, non-proliferative retinopathy involves blood vessel breakage and blood leakage. Proliferative retinopathy is more serious that there is new blood vessel growth in an abnormal way within the retina, which may cause scarring or retinal detachment.
Laser photocoagulation can be used to cause regression of leaking blood vessels and prevent new vessel growth. In more serious cases that involve vitreous humor, vitrectomy is needed.

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.
