There are some forms of macular degeneration that can cause a rapid deterioration of vision, unfortunately. These wet forms of macular degeneration involve the growth of blood vessels deep within the eye, and when those vessels leak or burst, they cause rapid loss of vision.
( Learn more) On average, it takes about 10 years to move from diagnosis to legal blindness, but there are some forms of macular degeneration that can cause sight loss in just days. ( Learn more) Age-related macular degeneration (AMD) is caused by changes beneath the sensitive tissues that communicate with your optic nerve and allow you to see.
With macular degeneration, a blind spot most often appears in the central visual field. If the disease progresses, the blurriness or darkness of the spot becomes larger and more severe, making it very difficult if not impossible to read, drive, or discern faces.
The first signs of Age-related Macular Degeneration are typically discovered by an eye doctor in an annual dilated eye exam. They include the presence of drusen – tiny but visible heaps of cell waste on the surface of the retina – and pigment changes in the macula.
SymptomsVisual distortions, such as straight lines seeming bent.Reduced central vision in one or both eyes.The need for brighter light when reading or doing close-up work.Increased difficulty adapting to low light levels, such as when entering a dimly lit restaurant.Increased blurriness of printed words.More items...•
During an eye exam, your eye doctor may use an Amsler grid to test for defects in your central vision. If you have macular degeneration, some of the straight lines in the grid will look faded, broken or distorted. Fluorescein angiography. During this test, your doctor injects a colored dye into a vein in your arm.

A thorough macular assessment is an essential part of a comprehensive or problem-oriented eye exam and can often reveal the underlying etiology of patient's vision loss.
The first sign you may notice is a gradual or sudden change in the quality of your vision or that straight lines appear distorted to you. This may gradually turn into a dramatic loss of your central vision. Other symptoms include: Dark, blurry areas or whiteout that appears in the center of your vision.
AMD negatively affects tasks including mobility, face recognition, perception of scenes, computer use, meal preparation, shopping, cleaning, watching TV, reading, driving and, in some cases, self-care. There is evidence for higher rates of depression among people with AMD than among community dwelling elderly.
Macular degeneration may have something to do with your genes. If someone in your family has it, your risk might be higher. Smoking, having high blood pressure or high cholesterol, obesity, eating lots of saturated fat, being light-skinned, being female, and having a light eye color are also risk factors.
Your eye doctor will use an Amsler grid, which is checkered and may have a dot located on it. For example, if you have wet AMD, you may see curved, distorted, or missing lines or blocks when you look at the center of the Amsler grid.
There are 3 vision tests that can be done at home: Amsler grid, distance vision, and near vision testing. This test helps detect macular degeneration . This is a disease that causes blurred vision, distortion, or blank spots. If you normally wear glasses for reading, wear them for this test.
The doctor may then take several types of pictures of your retina to record its current appearance and to help determine whether there’s any worsening in the future.
If your AMD progresses to the advanced “dry” form called “ geographic atrophy ,” which involves the slow, progressive wasting away and death of cells of the central retina (atrophy) with expansion of a central blind spot, then you may qualify to enroll in a clinical trial.
The diagnosis is made when the eye doctor sees tiny white spots in the retina when looking into your eyes with an ophthalmoscope. These spots are called “ drusen ,” which means “pebbles.”.
The device is designed to be used daily and takes approximately 3 minutes per eye.
Lifestyle Changes. Modifications to your lifestyle can also reduce your risk of AMD progression. If you have any form of AMD, you will be advised to eat lots of fruits and vegetables, and fatty fish (salmon, tuna, sardines, or mackerel twice a week). Smoking is a major risk factor, so smoking cessation is critical.
If you have lost a significant amount of central vision, then you should visit an optometrist called a “ low vision specialist .” These specialists will provide advice regarding appropriate magnifiers and lights to help you make optimal use of your remaining vision.
Your ophthalmologist will determine the required frequency by monitoring your progress with exams and retinal photographs. These injections may improve your vision, and are very likely to help prevent you from losing more central vision. Researchers are exploring longer-lasting treatments.
The fundus is another name for the back of your eye. These photographs provide the doctor with a clear image of your retina and the area around it. More than likely, after a few initial images a photo technician will inject a small amount of fluorescent dye into one of your arms. This dye helps the camera isolate the retina in images so your doctor can see it and any fluid in your eye more clearly. These images show the size and location of bleeds as well as how your doctor will monitor new or changing laquer cracks.
An Optical Coherence Tomography (OCT) scan shows the different layers of the retina. It can show the location and density of fluid or blood in the eye, scarring, macular thickness, and areas where the retina is being pushed upwards by abnormal blood vessels. My doctor relies on this more than the fundus image to determine if I have an active or benign bleed.
Up to 90 percent of cases are "dry" macular degeneration, according to the American Academy of Ophthalmology. Dry macular degeneration involves small deposits of fatty protein that form on the retina.
For wet macular degeneration, treatment is managed with eye injections at monthly or other intervals. These injections are used to block the growth of abnormal blood vessels. Less common treatments for advanced macular degeneration may include laser-based procedures such as photodynamic therapy and laser surgery.
Known as "eccentric viewing," it's a method patients can learn to take advantage of their intact peripheral vision. To manage low vision, Iyer says, "Ultimately, it's a combination of devices, strategies, lighting, contrast, training and resources.". For instance, she says, if your goal is to recognize a loved one's face, ...
By 2050, that figure will more than double, according to NEI projections. Macular degeneration is a disease of the retina. The retina records any images you see and transmits them to your brain through your optic nerve. The macula is the central portion of the retina and it's responsible for your central vision.
Age-related macular degeneration is the leading cause of visual loss in the U.S., according to the National Eye Institute. As the population ages, it will only become more common. In 2010, among adults ages 50 and older, nearly 2.1 million people had macular degeneration.
Prompt recognition of macular degeneration is important to avoid it advancing to the point where failing central vision means people can no longer recognize faces, Campbell says. That scenario can result if patients seek treatment in later stages, he says, when there's already a significant scar on the macula.
A common misconception is that macular degeneration typically leads to blindness. In fact, that's not the case for the vast majority of patients nowadays, says Dr. Peter Campbell, a retina specialist.
The American Macular Degeneration Foundation recognizes three phases of macular degeneration: early, intermediate, and late. Those phases are determined by the symptoms doctors can see as well as the symptoms you might report to a doctor. What you should do at each stage of the disorder varies.
Age-related macular degeneration (AMD) is caused by changes beneath the sensitive tissues that communicate with your optic nerve and allow you to see. In the dry form of the disease, which is the most common form, the damage begins with accumulations of yellow deposits below the retina, known as drusen.
The American Optometric Association reports that most people move through the process of diagnosis to legal blindness in about 10 years, but this is very much an estimate. Taking care of your health, using vitamins, and following the advice of your doctor may all be vital in helping you to slow this progression.
Losing weight if you are overweight. Your eyes rely on a healthy cardiovascular system, and that means paying attention to the choices that can harm your heart could be a key part of keeping AMD from progressing. You might start that work now and keep it up throughout the course of your AMD journey.
According to The American Journal of Managed Care, some people lose their sight within days of experiencing symptoms. This is why it's so vital for you to work with a doctor you can trust and explain your symptoms as soon as they appear.
If your doctor spots drusen, according to the Bright Focus Foundation, your doctor may request that you visit for eye exams frequently. That can allow your doctor to look for changes that indicate that the disease is progressing. It's vital to keep those appointments even if you feel fine.
In addition, people in intermediate stages may struggle to move from a bright location to a dim location, such as walking into a darkened movie theater on a sunny day, due to changes within their eyes. These changes may be subtle.
