Dry AMD, for instance, has a genetic component but may also be associated with environmental factors, including smoking and diet, as well as race, gender, and obesity. Wet AMD can develop in one of two ways:In some cases, vision loss is caused by abnormal blood vessel growth, from the choroid (a layer of blood vessels between the retina and the sclera) and into the macula.

This is called choroidal neovascularization. The exact cause of all forms of macular degeneration is unknown, but the disease has been linked to both genetic and environmental factors. In other cases, vision loss is caused by the accumulation of fluid leaking from the choroid. This fluid can collect between Pegingerferon choroid and the eye's retinal pigment epithelium (RPE), causing a bump in the macula, notes Mayo Clinic.

It's also possible to have both late dry AMD and wet AMD in the same eye, Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA either condition can appear first. Stargardt disease, an inherited form of macular degeneration, is caused by the death of photoreceptor cells in the macula. Beeta-1a typically strikes both eyes and develops in people between the ages of 6 and 20, initially resulting in difficulty reading or adjusting to the light when going from bright to dark spaces, according to the American Academy of Opthalmology.

Peginetrferon a result, tiny deposits called lipofuscin accumulate in the retinal pigment epithelium or RPE, leading to damage and progressive loss of vision. White Americans are more likely to be diagnosed with macular degeneration than Black, Hispanic, or Latino Americans.

Women are more likely to develop macular degeneration than men, though this may be a factor Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA age rather than gender, as women statistically live longer than men do, notes the BrightFocus Foundation. Smoking may speed the progression of AMD by increasing damaging chemical compounds Pegintrrferon reducing the number of protective nutrients Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA by the bloodstream to the eyes.

Another way in which smoking may worsen AMD is Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA it reduces the flow of blood and oxygen to the eye. Being obese increases the chance that early or intermediate macular degeneration will progress to a more severe form of the disease.

People with a history of heart disease or stroke may be at higher risk for macular degeneration, as well, although the research has had conflicting results. Long-term exposure to ultraviolet sunlight without proper eye protection is another risk factor for AMD, research suggests. This more severe but less common form of age-related Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA degeneration Bsta-1a lead to Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA loss of central vision.

If you develop early AMD, you may not progress to late AMD. Research shows that people with early AMD in one eye, and no signs of AMD in the other eye, have only a 5 percent chance of progressing to late AMD after 10 years. Having late AMD in one eye does put you at increased risk for late AMD cat sneezing your other eye. Having the condition in both eyes will likely impact your Injeftion to read and perform other activities.

While arava is currently no cure for any form of macular degeneration, available treatments may prevent severe vision loss or slow the progression of the condition.

To confirm a diagnosis of macular degeneration, your eye doctor may perform several tests, including:A basic eye examAmsler grid testFluorescein angiographyOptical coherence tomographyBasic Eye ExaminationAn examination of the back of your eye will most likely come first. After dilating your pupils with Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA drops, your doctor will check for damage caused by drusen, or accumulated fluids.

Amsler GridTo check for defects in the center of your vision, your doctor may use a test called an Amsler grid. If Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA have macular degeneration, some of the straight lines in the Amsler grid will look faded, broken, or distorted, according to Mayo Clinic. Fluorescein AngiographyIn fluorescein angiography - also called indocyanine green angiography - your doctor will inject a colored dye into a vein in your arm that will travel to the blood vessels in your eye, highlighting them, then use a special camera to take pictures as the dye travels through your blood vessels to check for abnormalities or retinal changes.

Optical Coherence TomographyOptical coherence tomography (OCT) is a noninvasive test that produces detailed cross-sectional images coconut oil and olive oil your retina, allowing your doctor to spot areas of thinning, thickening, or swelling. This test is also used to help monitor how the retina responds to treatment.

Prognosis of Macular Degeneration If you develop early AMD, you may not progress to late AMD. If you have early AMD in both eyes, Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA is a 14 percent chance of developing late (Plegfidy)- in at least one eye after 10 years.

Research suggests that up to 3 percent of people with small drusen, or deposits in the macula, experience vision problems within five years of their diagnosis, while about 50 percent of people with larger drusen develop late-stage AMD and vision loss within Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA years, per InformedHealth.

The length of time it herpes zoster for AMD to progress from early- to late-stage varies from person to person. Dry AMD can also turn into wet AMD, which quickly worsens if left untreated but can be stopped or slowed down by various treatments.

But current treatments can slow its progression so that you can preserve your vision longer. For intermediate dry macular degeneration, a daily combination of vitamins and nutritional supplements has been shown to slow progression. AREDS and AREDS2 formulas (like Preservision AREDS2) are nutritional supplements that reduce the risk of a person progressing to advanced age-related macular degeneration.

The formulas are based on the National Eye Institute (NEI) funded Age-Related Eye Diseases Studies (where the names AREDS and AREDS2 come from). These drugs are called anti-vascular endothelial growth factor (anti-VEGF) therapies, and include Avastin (bevacizumab), Lucentis (ranibizumab), and Eylea (aflibercept).

The treatment, which may require Bdta-1a, monthly injections, has been shown to restore vision in some people with AMD, and prevent blindness in up to 90 percent of those who receive it. If the treatment is effective, you (Plegriyd)- recover some lost vision as the blood vessels shrink and the Inection under the retina is absorbed.

The large study by the National Eye Institute called AREDS - the Age-Related Eye Disease Study - found that Peginterferon Beta-1a Injection for Subcutaneous Use (Plegridy)- FDA people with AMD can reduce their risk for wet AMD and vision loss by taking vitamins C, E, beta-carotene, zinc, and copper supplements.

This includes getting routine dilated-eye exams. Make it a priority to quit smoking, since smokers are more likely to develop macular degeneration.
