Question: What causes COPD ?
Answer: COPD is a disease that slowly worsens over time, especially if you continue to smoke. If you have COPD, you are more likely to have lung infections, which can be fatal. If the lungs are severely damaged, the heart may be affected. A person with COPD dies when the lungs and heart are unable to function and get oxygen to the body's organs and tissues, or when a complication, such as a severe infection, occurs. Treatment for COPD may help prevent complications, prolong life, and improve a person's quality of life.

Question: What causes COPD ?
Answer: Cigarette smoking is the most common cause of COPD. Most people with COPD are smokers or have been smokers in the past. Breathing in other fumes and dusts over long periods of time can also lead to COPD. Pipe, cigar, and other types of tobacco smoking can cause COPD, especially if the smoke is inhaled. Exposure to secondhand smoke can play a role in causing COPD. Most people with COPD are at least 40 years old or around middle age when symptoms start.

Question: What are the symptoms of COPD ?
Answer: The most common symptoms of COPD are a cough that does not go away and coughing up a lot of sputum (mucus). These symptoms may occur years before lung damage has reduced the flow of air in and out of the lungs. Other symptoms of COPD include shortness of breath, especially with exercise; wheezing (a whistling sound when you breathe); and tightness in the chest.

Question: How to diagnose COPD ?
Answer: To confirm a COPD diagnosis, a doctor will use a breathing test called spirometry. The test is easy and painless. It shows how well the lungs are working. The spirometer measures how much air the lungs can hold and how fast air is blown out of the lungs. Other tests, such as bronchodilator reversibility testing, a chest X-ray, and arterial blood gas test, may be ordered.

Question: How to diagnose COPD ?
Answer: If you have not been exercising regularly, you should get the advice of your doctor before starting. The symptoms of COPD are different for each person. People with mild COPD may not have much difficulty walking or exercising. As the symptoms of COPD get worse over time, a person may have more difficulty with walking and exercising. You should talk to your doctor about exercising and whether you would benefit from a pulmonary or lung rehabilitation program.

Question: How to prevent COPD ?
Answer: If you smoke, the most important thing you can do to prevent more lung damage is to stop smoking. It is also important to stay away from people who smoke and places where you know there will be smokers. Avoid exposure to pollutants like dust, fumes, and poor air quality, and take precautions to prevent flu and pneumonia. Following your doctor's instructions with medications and rehabilitative treatment can help alleviate COPD symptoms and control the disabling effects of the disease.

Question: What are the treatments for COPD ?
Answer: Bronchodilators and inhaled steroids are two medications used to treat COPD. Bronchodilators work by relaxing the muscles around the airways, opening them and making it easier to breathe. People with mild COPD take bronchodilators using an inhaler only when needed. Those with moderate or severe COPD may need more regular treatment. Inhaled steroids also are used for people with moderate or severe COPD in order to reduce swelling in the airways.

Question: What are the symptoms of COPD ?
Answer: Call your doctor right away if your symptoms worsen suddenly. People with COPD may have symptoms that suddenly get worse. When this happens, you have a much harder time catching your breath. Symptoms that worsen suddenly can include sudden chest tightness, more coughing, a change in your sputum (mucus), or fever. Your doctor will look at things that may be causing these sudden symptoms. Sometimes the symptoms are caused by a lung infection.

Topic: Age-related Macular Degeneration
Question: What is (are) Age-related Macular Degeneration ?
Answer: Age-related macular degeneration, also known as AMD, is an eye disease that affects the macula, a part of the retina. The retina sends light from the eye to the brain, and the macula allows you to see fine detail. AMD Blurs Central Vision AMD blurs the sharp central vision you need for straight-ahead activities such as reading, sewing, and driving. AMD causes no pain. How AMD Progresses In some cases, AMD advances so slowly that people notice little change in their vision. In others, the disease progresses faster and may lead to a loss of vision in both eyes. AMD is a common eye condition among people age 50 and older. It is a leading cause of vision loss in older adults. Two Forms of AMD There are two forms of age-related macular degeneration -- dry and wet.

Topic: Age-related Macular Degeneration
Question: What are the symptoms of Age-related Macular Degeneration ?
Answer: AMD is detected during a comprehensive eye exam that includes a visual acuity test, a dilated eye exam, and tonometry. Tests for AMD - The visual acuity test is an eye chart test that measures how well you see at various distances.  - In the dilated eye exam, drops are placed in your eyes to widen, or dilate, the pupils. Then, your eye care professional uses a special magnifying lens to examine your retina and optic nerve for signs of AMD and other eye problems. After the exam, your close-up vision may remain blurred for several hours.  - With tonometry, an instrument measures the pressure inside the eye. Numbing drops may be applied to your eye for this test. The visual acuity test is an eye chart test that measures how well you see at various distances.

Your eye care professional also may do other tests to learn more about the structure and health of your eye. The Amsler Grid During an eye exam, you may be asked to look at an Amsler grid, shown here. You will cover one eye and stare at a black dot in the center of the grid. While staring at the dot, you may notice that the straight lines in the pattern appear wavy. You may notice that some of the lines are missing. These may be signs of AMD. Because dry AMD can turn into wet AMD at any time, you should get an Amsler grid from your eye care professional. You could then use the grid every day to evaluate your vision for signs of wet AMD. The Fluorescein Angiogram Test If your eye care professional believes you need treatment for wet AMD, he or she may suggest a fluorescein angiogram. In this test, a special dye is injected into your arm. Pictures are taken as the dye passes through the blood vessels in your eye. The test allows your eye care professional to identify any leaking blood vessels and recommend treatment.

Question: What is (are) Age-related Macular Degeneration ?
Answer: Wet AMD occurs when abnormal blood vessels behind the retina start to grow under the macula. With wet AMD, loss of central vision can occur quickly. Wet AMD is considered to be advanced AMD and is more severe than the dry form.

Topic: Age-related Macular Degeneration
Question: What is (are) Age-related Macular Degeneration ?
Answer: Dry AMD occurs when the light-sensitive cells in the macula slowly break down, gradually blurring central vision in the affected eye. As dry AMD gets worse, you may see a blurred spot in the center of your vision. Over time, as less of the macula functions, central vision in the affected eye can be lost. If you have vision loss from dry AMD in one eye only, you may not notice any changes in your overall vision. With the other eye seeing clearly, you can still drive, read, and see fine details. You may notice changes in your vision only if AMD affects both eyes. If you experience blurry vision, see an eye care professional for a comprehensive dilated eye exam.

Topic: Age-related Macular Degeneration
Question: What is (are) Age-related Macular Degeneration ?
Answer: Dry AMD has three stages -- early AMD, intermediate AMD, and advanced dry AMD. All of these may occur in one or both eyes. People with early dry AMD have either several small drusen or a few medium-sized drusen. Drusen are yellow deposits under the retina which often are found in people over age 50. People with early AMD have no symptoms and no vision loss. People with intermediate dry AMD have either many medium-sized drusen or one or more large drusen. Some people see a blurred spot in the center of their vision. More light may be needed for reading and other tasks. In addition to drusen, people with advanced dry AMD have a breakdown of light-sensitive cells and supporting tissue in the macula. This breakdown can cause a blurred spot in the center of your vision. Over time, the blurred spot may get bigger and darker, taking more of your central vision. You may have difficulty reading or recognizing faces until they are very close to you.

Question: What causes Age-related Macular Degeneration ?
Answer: Drusen alone do not usually cause vision loss. In fact, scientists are unclear about the connection between drusen and AMD. They do know that an increase in the size or number of drusen raises a person's risk of developing either advanced dry AMD or wet AMD. These changes can cause serious vision loss.

Question: What are the symptoms of Age-related Macular Degeneration ?
Answer: The most common symptom of dry AMD is slightly blurred vision. You may have difficulty recognizing faces. You may need more light for reading and other tasks. Dry AMD generally affects both eyes, but vision can be lost in one eye while the other eye seems unaffected. One of the most common early signs of dry AMD is drusen. Drusen are yellow deposits under the retina. They often are found in people over age 50. Your eye care professional can detect drusen during a comprehensive dilated eye exam.

Question: What is (are) Age-related Macular Degeneration ?
Answer: The AREDS formulation is a combination of antioxidants and zinc that is named for a study conducted by The National Eye Institute called the Age-Related Eye Disease Study, or AREDS. This study found that taking a specific high-dose formulation of antioxidants and zinc significantly reduced the risk of advanced AMD and its associated vision loss. Slowing AMD's progression from the intermediate stage to the advanced stage will save many people's vision.

Question: How to prevent Age-related Macular Degeneration ?
Answer: There is no reason for those diagnosed with early stage AMD to take the AREDS formulation. The study did not find that the formulation helped those with early stage AMD. If you have early stage AMD, a comprehensive dilated eye exam every year can help determine if the disease is progressing. If early stage AMD progresses to the intermediate stage, discuss taking the formulation with your doctor.

Topic: Diabetic Retinopathy
Question: What is (are) Diabetic Retinopathy ?
Answer: Can Cause Vision Loss, Blindness Diabetic retinopathy is a complication of diabetes and a leading cause of blindness. It occurs when diabetes damages the tiny blood vessels inside the retina in the back of the eye. A healthy retina is necessary for good vision. If you have diabetic retinopathy, at first you may notice no changes to your vision. But over time, diabetic retinopathy can get worse and cause vision loss. Diabetic retinopathy usually affects both eyes. Four Stages The four stages of diabetic retinopathy are - mild nonproliferative retinopathy  - moderate nonproliferative retinopathy  - severe nonproliferative retinopathy  - proliferative retinopathy. mild nonproliferative retinopathy moderate nonproliferative retinopathy severe nonproliferative retinopathy proliferative retinopathy. The first stage is mild nonproliferative retinopathy. At this earliest stage, there are small areas of balloon-like swelling in the retina's tiny blood vessels. The second stage is moderate nonproliferative retinopathy. As the disease progresses, some blood vessels that nourish the retina are blocked. The third stage is severe nonproliferative retinopathy. Many more blood vessels are blocked, depriving several areas of the retina of their blood supply. These areas send signals to the body to grow new blood vessels for nourishment. The fourth stage is proliferative retinopathy. At this advanced stage, the signals sent by the retina for nourishment cause the growth of new blood vessels. These new blood vessels are abnormal and fragile. The new blood vessels grow along the retina and along the surface of the clear, vitreous gel that fills the inside of the eye. By themselves, these blood vessels do not cause symptoms or vision loss. However, they have thin, fragile walls. If they leak blood, severe vision loss and even blindness can result. Other Diabetic Eye Diseases In addition to diabetic retinopathy, other diabetic eye diseases that people with diabetes may face are cataract and glaucoma. See this graphic for a quick overview of diabetic eye disease, including how many people it affects, whos at risk, what to do if you have it, and how to learn more.

Topic: Diabetic Retinopathy
Question: What causes Diabetic Retinopathy ?
Answer: Who Is at Risk? All people with diabetes -- both type 1 and type 2 -- are at risk for diabetic retinopathy. People with diabetes are also at increased risk for cataract and glaucoma. That's why everyone with diabetes should get a comprehensive dilated eye exam at least once a year. Between 40 to 45 percent of Americans diagnosed with diabetes have some stage of diabetic retinopathy. If you have diabetic retinopathy, your doctor can recommend treatment to help prevent its progression. How Vision Loss Occurs Blood vessels damaged from diabetic retinopathy can cause vision loss in two ways. Fragile, abnormal blood vessels can develop and leak blood into the center of the eye, blurring vision. This is proliferative retinopathy and is the fourth and most advanced stage of the disease. Fluid can leak into the center of the macula, the part of the eye where sharp, straight-ahead vision occurs. The fluid makes the macula swell, blurring vision. This condition is called macular edema. Macular edema can occur at any stage of diabetic retinopathy, although it is more likely to occur as the disease progresses. About half of the people with proliferative retinopathy also have macular edema. Macular edema can occur at any stage of diabetic retinopathy, although it is more likely to occur as the disease progresses. About half of the people with proliferative retinopathy also have macular edema. Have Dilated Eye Exams The National Eye Institute (NEI) urges everyone with diabetes to have a comprehensive dilated eye exam at least once a year. If you have diabetic retinopathy, you may need an eye exam more often. People with proliferative retinopathy can reduce their risk of blindness by 95 percent with timely treatment and appropriate follow-up care.  Watch an animation to see what a comprehensive dilated eye exam includes.
