Check your Eye Whether You are At Risk of Glaucoma or Not

Many people have some type of visual problem at some point in their lives. Some can no longer see objects far away. Others have problems reading small print. These types of conditions are often easily treated with eyeglasses or contact lenses.


But when one or more parts of the eye or brain that are needed to process images become diseased or damaged, severe or total loss of vision can occur. In these cases, vision can't be fully restored with medical treatment, surgery, or corrective lenses like glasses or contacts.

Glaucoma can be regarded as a group of diseases that have as a common end point a characteristic optic neuropathy which is determined by both structural change and functional deficit. The medical understanding of the nature of glaucoma has changed profoundly in the past few years and a precise comprehensive definition and diagnostic criteria are yet to be finalised. There are several types of glaucoma, however, the two most common are primary open angle glaucoma (POAG), having a slow and insidious onset, and angle closure glaucoma (ACG), which is less common and tends to be more acute.

A simple model was developed to estimate the extent of glaucoma on a regional basis, taking into account demographic data, e.g., age distribution, gender and ethnic groups. Overall, the results demonstrate that glaucoma is responsible for approximately 5.2 million blind (15% of the total burden of world blindness).

Seeing into our future is all part of good eye health.Eye diseases like cataracts, glaucoma, and age-related macular degeneration become more common as people get older.But there are some things people can do to help maintain clear eyesight.The key is to recognize changes in your eyesight and to get regular eye exams. Our eyes actually start to age at birth, but most people begin to notice changes in their eyes and in their vision during their forties.

Cross-sectional studies and those using national data sets estimate that glaucoma-related blindness is between six and eight times more common among black Americans than among whites. Community-based studies have found that glaucoma is four to six times more prevalent among blacks.Older black Americans are not receiving potentially sight-saving care for open-angle glaucoma at the same rate as older white Americans.

Glaucoma was once thought of as a single disease, but it is actually a group of diseases in which gradual damage to the optic nerve can cause blindness.Because glaucoma appears gradually, without warning symptoms, about half of those who have the disease aren't aware of it until considerable damage has already occurred.Early detection is especially important for those at highest risk for the disease--African Americans over the age of 40, all people over the age of 60, and those with a family history of glaucoma. About three million people in the United States have glaucoma, and as many as 120,000 have lost their vision to the disease.

Diabetic retinopathy is a leading cause of blindness in American adults. It is caused by changes in the blood vessels of the retina. In some people with diabetic retinopathy, retinal blood vessels may swell and leak fluid, while in others, abnormal new blood vessels grow on the surface of the retina.ll can cause severe vision loss or even blindness. Diabetic eye disease can often be treated before vision loss occurs. All people with diabetes should have a dilated eye exam at least once a year.

Ocular pressure in any patient older than 40 years have to be measured systematically, also examination of optic disc and especially the investigation of visual field in suspected patients preferably with automated perimetry rare are crucial.A study shown that majority of primary open angle glaucoma patients presented for their treatment at very late stage. Out of the 148 eyes, 54 eyes were in advanced [.8 and .9 cup disc ratio] stage of optic disc cupping and 30 eyes had complete glaucomatous optic atrophy.

An eye exam is one of the best ways to protect your vision because it can detect eye problems at their earliest stage — when they'are most treatable. Regular eye exams give your eye care professional a chance to help you correct or adapt to vision changes. And eye care specialists can give you expert tips on reducing eyestrain and caring for your eyes.

More than four million Americans have glaucoma, an eye disease that damages the optic nerve and destroys eyesight. However, nearly half of those with glaucoma are not even aware they have it. Are you one of them? You owe it to yourself to find out by getting a dilated eye exam. With its painless and gradual loss of vision, glaucoma comes with no early warning signs, but it can be detected during a comprehensive dilated eye exam. In an effort to encourage Americans to make vision a health priority, the National Eye Institute (NEI), one of the Federal government’s National Institutes of Health (NIH), observes Healthy Vision Month each May. This year’s observance highlights the importance for early detection of glaucoma.

Paul A. Sieving, M.D., Ph.D., director of the NEI, said, “NEI-funded research has shown that treatment during the early stages of glaucoma can control the disease and prevent future vision loss and blindness. This is why NEI encourages people at higher risk for glaucoma to get a comprehensive dilated eye exam every one to two years.”

Those at higher risk for developing glaucoma include:

With a dilated eye exam, an eye care professional can see inside the eye to detect signs of glaucoma, such as subtle changes to the optic nerve and other vision problems, before any symptoms appear. This allows the eye care professional to monitor patients and treat glaucoma as early as possible.

“A dilated eye examination is essential to protecting the vision of those at higher risk for glaucoma,” noted Anne L. Coleman, M.D., Ph.D., Frances and Ray Stark Professor of Ophthalmology at UCLA’s Jules Stein Eye Institute and chair of the glaucoma subcommittee for NEI’s National Eye Health Education Program. “If glaucoma is detected early, treatments such as medication, conventional surgery, or laser surgery can slow or stop vision loss. High pressure inside the eye, which may be associated with glaucoma, does not by itself mean that you have glaucoma. Only a dilated eye exam and evaluation of the optic nerve can tell you that.”
