What is (are) Glaucoma ?
Glaucoma is a group of diseases that can damage the eye's optic nerve and result in vision loss and blindness. While glaucoma can strike anyone, the risk is much greater for people over 60. How Glaucoma Develops  There are several different types of glaucoma. Most of these involve the drainage system within the eye. At the front of the eye there is a small space called the anterior chamber. A clear fluid flows through this chamber and bathes and nourishes the nearby tissues. (Watch the video to learn more about glaucoma. To enlarge the video, click the brackets in the lower right-hand corner. To reduce the video, press the Escape (Esc) button on your keyboard.) In glaucoma, for still unknown reasons, the fluid drains too slowly out of the eye. As the fluid builds up, the pressure inside the eye rises. Unless this pressure is controlled, it may cause damage to the optic nerve and other parts of the eye and result in loss of vision. Open-angle Glaucoma The most common type of glaucoma is called open-angle glaucoma. In the normal eye, the clear fluid leaves the anterior chamber at the open angle where the cornea and iris meet. When fluid reaches the angle, it flows through a spongy meshwork, like a drain, and leaves the eye. Sometimes, when the fluid reaches the angle, it passes too slowly through the meshwork drain, causing the pressure inside the eye to build. If the pressure damages the optic nerve, open-angle glaucoma -- and vision loss -- may result. There is no cure for glaucoma. Vision lost from the disease cannot be restored. However, there are treatments that may save remaining vision. That is why early diagnosis is important.  See this graphic for a quick overview of glaucoma,  including how many people it affects, whos at risk, what to do if you have it, and how to learn more.  See a glossary of glaucoma terms. + NIHSeniorHealth + Glaucoma
What causes Glaucoma ?
Nearly 2.7 million people have glaucoma, a leading cause of blindness in the United States. Although anyone can get glaucoma, some people are at higher risk. They include - African-Americans over age 40  - everyone over age 60, especially Hispanics/Latinos  - people with a family history of glaucoma. African-Americans over age 40 everyone over age 60, especially Hispanics/Latinos people with a family history of glaucoma.  In addition to age, eye pressure is a risk factor. Whether you develop glaucoma depends on the level of pressure your optic nerve can tolerate without being damaged. This level is different for each person. Thats why a comprehensive dilated eye exam is very important. It can help your eye care professional determine what level of eye pressure is normal for you. Another risk factor for optic nerve damage relates to blood pressure. Thus, it is important to also make sure that your blood pressure is at a proper level for your body by working with your medical doctor.

What are the symptoms of Glaucoma ?
Symptoms of Glaucoma  Glaucoma can develop in one or both eyes. The most common type of glaucoma, open-angle glaucoma, has no symptoms at first. It causes no pain, and vision seems normal. Without treatment, people with glaucoma will slowly lose their peripheral, or side vision. They seem to be looking through a tunnel. Over time, straight-ahead vision may decrease until no vision remains. Tests for Glaucoma Glaucoma is detected through a comprehensive eye exam that includes a visual acuity test, visual field test, dilated eye exam, tonometry, and pachymetry. (Watch the animated video to learn more about testing for glaucoma. To enlarge the video, click the brackets in the lower right-hand corner. To reduce the video, press the Escape (Esc) button on your keyboard.)  A visual acuity test uses an eye chart test to measure how well you see at various distances. A visual field test measures your side or peripheral vision. It helps your eye care professional tell if you have lost side vision, a sign of glaucoma. In a dilated eye exam, drops are placed in your eyes to widen, or dilate, the pupils. Your eye care professional uses a special magnifying lens to examine your retina and optic nerve for signs of damage and other eye problems. After the exam, your close-up vision may remain blurred for several hours. In tonometry, an instrument measures the pressure inside the eye. Numbing drops may be applied to your eye for this test. With pachymetry,  a numbing drop is applied to your eye. Your eye care professional uses an ultrasonic wave instrument to measure the thickness of your cornea. + NIHSeniorHealth + Glaucoma
What are the treatments for Glaucoma ?
Although open-angle glaucoma cannot be cured, it can usually be controlled. While treatments may save remaining vision, they do not improve sight already lost from glaucoma. The most common treatments for glaucoma are medication and surgery. Medications  Medications for glaucoma may be either in the form of eye drops or pills. Some drugs reduce pressure by slowing the flow of fluid into the eye. Others help to improve fluid drainage. (Watch the video to learn more about coping with glaucoma. To enlarge the video, click the brackets in the lower right-hand corner. To reduce the video, press the Escape (Esc) button on your keyboard.) For most people with glaucoma, regular use of medications will control the increased fluid pressure. But, these drugs may stop working over time. Or, they may cause side effects. If a problem occurs, the eye care professional may select other drugs, change the dose, or suggest other ways to deal with the problem.  Read or listen to ways some patients are coping with glaucoma. Surgery Laser surgery is another treatment for glaucoma. During laser surgery, a strong beam of light is focused on the part of the anterior chamber where the fluid leaves the eye. This results in a series of small changes that makes it easier for fluid to exit the eye. Over time, the effect of laser surgery may wear off. Patients who have this form of surgery may need to keep taking glaucoma drugs. Researching Causes and Treatments Through studies in the laboratory and with patients, NEI is seeking better ways to detect, treat, and prevent vision loss in people with glaucoma. For example, researchers have discovered genes that could help explain how glaucoma damages the eye. NEI also is supporting studies to learn more about who is likely to get glaucoma, when to treat people who have increased eye pressure, and which treatment to use first. + NIHSeniorHealth + Glaucoma

How to prevent Glaucoma ?
At this time, we do not know how to prevent glaucoma. However, studies have shown that the early detection and treatment of glaucoma, before it causes major vision loss, is the best way to control the disease. So, if you fall into one of the higher risk groups for the disease, make sure to have a comprehensive dilated eye exam at least once every one to two years.

Who is at risk for High Blood Pressure? ?
Not a Normal Part of Aging Nearly 1 in 3 American adults have high blood pressure. Many people get high blood pressure as they get older. However, getting high blood pressure is not a normal part of aging. There are things you can do to help keep your blood pressure normal, such as eating a healthy diet and getting more exercise. Risk Factors Anyone can develop high blood pressure. However, these factors can increase your risk for developing high blood pressure. -  age  - race or ethnicity  - being overweight  - gender  - lifestyle habits  - a family history of high blood pressure.  age race or ethnicity being overweight gender lifestyle habits a family history of high blood pressure. Age Blood pressure tends to rise with age. In fact, about 65 percent of Americans age 60 or older have high blood pressure. Race/Ethnicity High blood pressure is more common in African American adults than in Caucasian or Hispanic American adults. Compared with these ethnic groups, African Americans -  tend to get high blood pressure earlier in life  - often have higher blood pressure numbers  - are less likely to achieve target blood pressure goals with treatment. tend to get high blood pressure earlier in life often have higher blood pressure numbers are less likely to achieve target blood pressure goals with treatment. Overweight You are more likely to develop prehypertension or high blood pressure if youre overweight or obese. The terms overweight and obese refer to body weight thats greater than what is considered healthy for a certain height. Gender Before age 55, men are more likely than women to develop high blood pressure. After age 55, women are more likely than men to develop high blood pressure. Lifestyle Habits Unhealthy lifestyle habits can raise your risk for high blood pressure, and they include -  eating too much sodium or too little potassium   - lack of physical activity  - drinking too much alcohol  - smoking  - stress. eating too much sodium or too little potassium lack of physical activity drinking too much alcohol smoking stress. Family History A family history of high blood pressure raises the risk of developing prehypertension or high blood pressure. Some people have a high sensitivity to sodium and salt, which may increase their risk for high blood pressure and may run in families. Genetic causes of this condition are why family history is a risk factor for this condition. + NIHSeniorHealth + High Blood Pressure
What is (are) High Blood Pressure ?
Blood pressure is the force of blood pushing against the walls of the blood vessels as the heart pumps blood. If your blood pressure rises and stays high over time, its called high blood pressure. High blood pressure is dangerous because it makes the heart work too hard, and the high force of the blood flow can harm arteries and organs such as the heart, kidneys, brain, and eyes. + NIHSeniorHealth + High Blood Pressure
What is (are) High Blood Pressure ?
Normal blood pressure for adults is defined as a systolic pressure below 120 mmHg and a diastolic pressure below 80 mmHg. It is normal for blood pressures to change when you sleep, wake up, or are excited or nervous. When you are active, it is normal for your blood pressure to increase. However, once the activity stops, your blood pressure returns to your normal baseline range. Blood pressure normally rises with age and body size. Newborn babies often have very low blood pressure numbers that are considered normal for babies, while older teens have numbers similar to adults. + NIHSeniorHealth + High Blood Pressure
What is (are) High Blood Pressure ?
High blood pressure is a common disease in which blood flows through blood vessels (arteries) at higher than normal pressures. There are two main types of high blood pressure: primary and secondary high blood pressure. Primary, or essential, high blood pressure is the most common type of high blood pressure. This type of high blood pressure tends to develop over years as a person ages. Secondary high blood pressure is caused by another medical condition or use of certain medicines. This type usually resolves after the cause is treated or removed. + NIHSeniorHealth + High Blood Pressure

Abnormal blood pressure is higher than 120/80 mmHg. If either your systolic or diastolic blood pressure is higher than normal (120/80) but not high enough to be considered high blood pressure (140/90), you have pre-hypertension. Pre-hypertension is a top number between 120 and 139 or a bottom number between 80 and 89 mmHg. For example, blood pressure readings of 138/82, 128/70, or 115/86 are all in the "pre-hypertension" range. (Click the table on the right to see the stages of high blood pressure in adults.) The ranges in the table are blood pressure guides for adults who do not have any short-term serious illnesses. People with diabetes or chronic kidney disease should keep their blood pressure below 130/80 mmHg. + NIHSeniorHealth + High Blood Pressure
How to prevent High Blood Pressure ?
You can take steps to help prevent high blood pressure by adopting these healthy lifestyle habits. - Follow a healthy eating plan like DASH (Dietary Approaches to Stop Hypertension), which emphasizes fruits, vegetables, fat-free and low-fat milk and milk products, and whole grains, fish, poultry, beans, seeds, and nuts, and choose and prepare foods with less sodium (salt).

What are the treatments for High Blood Pressure ?
High blood pressure is treated with lifestyle changes and medicines. Treatment can help control blood pressure, but it will not cure high blood pressure, even if your blood pressure readings appear normal. If you stop treatment, your blood pressure and risk for related health problems will rise. For a healthy future, follow your treatment plan closely.

Two key measures are used to determine if someone is overweight or obese. These are body mass index, or BMI, and waist circumference. Body mass index (BMI) is a measure of weight in relation to height, and provides an estimate of your total body fat. As your BMI goes up, so do your chances of getting high blood pressure, heart disease, and other health problems. A BMI -  below 18.5 is a sign that you are underweight.  - between 18.5 and 24.9 is in the healthy range.  - between 25 and 29.9 is considered overweight.  - of 30 or more is considered obese.  below 18.5 is a sign that you are underweight. between 18.5 and 24.9 is in the healthy range. between 25 and 29.9 is considered overweight. of 30 or more is considered obese. See the Body Mass Index Table, available from the National Heart, Lung, and Blood Institute (NHLBI). Body mass index (BMI) applies to both men and women, but it does have some limits. - It may overestimate body fat in in someone who is very muscular or who has swelling from fluid retention (called edema)  - It may underestimate body fat in older persons and others who have lost muscle mass. It may overestimate body fat in in someone who is very muscular or who has swelling from fluid retention (called edema) It may underestimate body fat in older persons and others who have lost muscle mass. Thats why waist measurement is often checked as well. Another reason is that too much body fat in the stomach area also increases disease risk. A waist measurement of more than 35 inches in women and more than 40 inches in men is considered high. + NIHSeniorHealth + High Blood Pressure

Blood pressure rises as body weight increases. Losing even 10 pounds can lower blood pressure -- and it has the greatest effect for those who are overweight and already have hypertension. If you are overweight or obese, work with your health care provider to develop a plan to help you lower your weight and maintain a healthy weight. Aim to reduce your weight by 7 to 10 percent over six months, which can lower your risk for health problems. For example, if you are overweight at 200 pounds, try to lose 14 to 20 pounds over six months. After that, you may have to continue to lose weight to get to a healthy weight. + NIHSeniorHealth + High Blood Pressure

"DASH" stands for "Dietary Approaches to Stop Hypertension." This is the name of a clinical study that tested the effects of nutrients in food on blood pressure. Study results indicated that you can reduce high blood pressure by following an eating plan that emphasizes fruits, vegetables, and fat-free or low-fat milk and milk products, and that is low in saturated fat, cholesterol, total fat, and added sugars. The DASH eating plan also includes whole grains, poultry, fish, and nuts, and has reduced amounts of red meats, sweets, added sugars, and beverages containing sugars. A second study, called "DASH-Sodium," showed that eating less salt also lowered blood pressure in people following either the DASH eating plan or the typical American diet. But those following DASH, especially those with high blood pressure, benefited the most.

Only a small amount of the salt that we eat comes from the salt shaker, and only small amounts occur naturally in food. Most of the salt that we eat comes from processed foods -- for example, canned or processed meat, baked goods, and certain cereals, and foods with soy sauce, seasoned salts, monosodium glutamate (MSG), and baking soda. Food from fast food restaurants, frozen foods, and canned foods also tend to be higher in sodium. + NIHSeniorHealth + High Blood Pressure
