You should also tell your doctor about any vision changes you experience. Your doctor can conduct a variety of tests to diagnose macular degeneration. For example, your doctor can use special eye drops to dilate your eyes and then check the back of your eyes for signs of fluid, blood, or yellow deposits. During an eye exam, your doctor can also check your field of central vision by asking you to look at a grid.

You should also tell your doctor about any vision changes you experience. Your doctor can conduct a variety of tests to diagnose macular degeneration. For example, your doctor can use special eye drops to dilate your eyes and then check the back of your eyes for signs of fluid, blood, or yellow deposits.
During an eye exam, your doctor can also check your field of central vision by asking you to look at a grid. If some of the lines on the grid appear faded or broken, this can be a sign of macular degeneration. Other tests include the following: Fluorescein angiography Your doctor injects a colored dye into a vein in your arm to examine blood vessels in your eye. Indocyanine green angiography Indocyanine green angiography is similar to fluorescein angiography.
Your doctor injects indocyanine green dye. They can use this test to confirm the results of fluorescein angiography and to diagnose your type of macular degeneration. Optical coherence tomography This involves taking cross-sectional images of the retina and checking for swelling, thickening, or thinning. Complications of macular degeneration One of the complications of macular degeneration is being unable to perform certain tasks on your own.
As the disease progresses, it becomes increasingly difficult to drive, read, or complete other activities. As a result of vision loss, about 30 percent of people with macular degeneration experience some form of anxiety or depression.
Your doctor can suggest treatments to improve your mental health, such as medication, counseling, or a support group for people with vision impairments. Another complication is visual hallucinations.
As your vision decreases, your brain may compensate by creating false images or hallucinations. You should discuss your hallucinations with your doctor or a support group.
They can help you find ways to cope. No cure is available for macular degeneration, but your doctor can recommend options to slow the progression of the disease. Treatment for dry macular degeneration If you have dry macular degeneration, your doctor may suggest that you work with a low vision rehabilitation specialist.
The specialist can teach you how to adjust and cope with vision loss. Your doctor may also recommend surgery to help improve your vision. Also, your doctor may administer a medication directly into your eye to stop the growth of new blood vessels.
It can take several weeks of treatment before you notice a difference. Another treatment option is photodynamic therapy. Your doctor injects a medication into a vein in one of your arms and then uses a special laser to close up leaking blood vessels. This type of therapy can improve your vision, but you may need multiple treatments. Photocoagulation is another therapy for wet macular degeneration. This involves the use of high-energy laser beams to destroy abnormal blood vessels.
The purpose of this therapy is to stop bleeding and reduce further damage to your macula. However, the laser can cause scarring and leave a blind spot on your eye. However, you can reduce your risk of the disease by maintaining a healthy lifestyle. Early treatment can slow the progression of the disease and minimize vision loss.

Store What is Macular Degeneration? This entire site is dedicated to information regarding Macular Degeneration, but this page will give you a quick general overview to get you oriented. Macular Degeneration Macular Degeneration is the leading cause of vision loss, affecting more than 10 million Americans — more than cataracts and glaucoma combined. At present, Macular Degeneration is considered an incurable eye disease. Macular Degeneration is caused by the deterioration of the central portion of the retina, the inside back layer of the eye that records the images we see and sends them via the optic nerve from the eye to the brain.
Human eye cross-sectional view The pathogenesis of age-related macular degeneration is not well known, although some theories have been put forward, including oxidative stress, mitochondrial dysfunction, and inflammatory processes. The imbalance between the production of damaged cellular components and degradation leads to the accumulation of harmful products, for example, intracellular lipofuscin and extracellular drusen. Incipient atrophy is demarcated by areas of retinal pigment epithelium RPE thinning or depigmentation that precede geographic atrophy in the early stages of AMD. In the dry nonexudative form, cellular debris called drusen accumulates between the retina and the choroid , causing atrophy and scarring to the retina. In the wet exudative form, which is more severe, blood vessels grow up from the choroid neovascularization behind the retina which can leak exudate and fluid and also cause hemorrhaging.

No fumes. Opta por una dieta saludable. Las vitaminas antioxidantes que hay en las frutas y los vegetales contribuyen a mantener la salud de los ojos. Los alimentos que no son de carne comprenden leche, queso, yogur, cereales de grano entero y pan de trigo integral.
