Age-Related Macular Degeneration Types and Causes
Age-Related macular degeneration is a condition where the area of the eye becomes damaged due to damage done to the photoreceptors. The result can be vision loss in as little as a matter of months. Some people may not suffer from the dry form of the disease, while others may suffer in the wet form.
The typical symptoms of macular degeneration are nocturnal blindness, where objects such as close up objects, reading material or small moving objects cannot be seen clearly. In addition, you may find that your central vision is blurry at night. Another symptom would be the loss of peripheral vision. This means that you may have problems seeing small details at the back of your eye. If the disease progresses, you will start to lose central vision.
What happens when what is Age-related Macular Degeneration progresses?
When this starts to get worse, your ophthalmologist may recommend that you get cataract surgery. This is to remove the debris that is in your eye and improve your vision. The dry form tends to get worse over time, while the wet form tends to get worse when you get old.
What is Age-Related Macular Degeneration?
Damage to the retina actually happens when the blood vessels in the macula area become brittle and thin. As a result, these vessels leak and cause damage to the delicate tissue of the retina. As the result, the blood vessels often get smaller, which leads to a condition known as “angiogenesis.”
The wet form tends to be more common, while the dry form tends to be less common. The wet version of ARMD is called “Choroidal Neovascular Disease,” while the dry version is called “Unclear Retinopathy.” Both forms of ARMD can cause less common vision loss that can affect how central vision loss affects your ability to read.
Both wet and dry forms of ARMD are caused by the death and scarring of the macula
The wet form tends to happen more quickly, and it is less likely to heal than the dry form. This means that the dry ARMD is less likely to cause blindness. However, the wet ARMD may get worse and cause the loss of central vision. It has been discovered that some people have a genetic predisposition for having this disease.
This means that if you have parents who have suffered from ARMD, you also may get it in your future. The eye doctors say that the more likely a person is to get age-related macular degeneration, the greater the chance their eyes will eventually become damaged.
The less common dry form of ARMD is less common than the wet form, but both can lead to vision loss. The good news is that treatment can keep the dry form from getting worse. For the wet form, treatment options include medications, eye surgery, eye transplants, or an optometrist can use contact lenses to correct the problem.
This is also an inherited condition that is usually not as severe as dry ARMD. The most common type of ARMD is protein damage. With this type, proteins are not properly washed off the walls of the eyes. This leads to proteins building upon the walls of the retina and eventually it causes blurriness.
Wet ARMD is different than the dry form
With the ARMD, the protein build-up damages the cells of the macula. The protein builds up in the macula is what causes blurriness. This happens because the protein build-up is not washed off the walls of the eye very well. These three types of what is age-related macular degeneration are a leading cause of vision loss in seniors.
As you can see, the leading cause for vision loss is due to the dry type of macular degeneration and the protein build-up can be stopped. If it does happen to you, your eye doctor will help you with what is the most effective treatment. He or she will perform testing to make sure the disease is caught early on and the disease has not spread yet.
The testing that is usually done during the process of what is age-related macular degeneration is a form of cataract scanning. A high-powered lens is used to create a map of your eye. The test shows the areas of your retina that are damaged.
If the damaged areas are located in the central portion of your eyes, your doctor can conclude that you have suffered from ARMD and your central vision is at risk. However, if it is in the peripheral portion of your eyes, then it could simply mean your central part of the retina has suffered damage as well. Therefore, you need to visit an eye doctor as soon as possible.
