Macular Generation Tests

If you have noticed that your central vision is blurry, some simple macular degeneration tests can diagnose the condition and determine which type of the disease you have. The two types of macular degeneration include the 'wet' type and the 'dry' type. Dry macular degeneration, which is the most common, is caused by a deterioration of the eye lining near the macula. The damaged tissue and pigment in the lining of the eye causes central vision loss, making it very difficult for sufferers to focus on details, read, drive or perform many daily activities.

A very different process causes wet macular degeneration, and the macular degeneration symptoms can become much worse, leading to more serious vision loss if it is not diagnosed and treated. Wet macular degeneration is the result of abnormal blood cell growth near the retina that leaks fluids and blood. The fluid leaks can damage or destroy light-sensitive cells in the eye, and when those cells die they can create permanent blind spots.

Types of Macular Generation Tests

Two of the most common macular degeneration tests include pupil dilation and the Amsler Grid Test. Pupil dilation is a procedure where your eye doctor uses special eye drops to enlarge your pupils. As your pupils dilate, your eye doctor can get a better view of the back of your eye and retina. Using a bright light and magnifying device, your eye care specialist can often see abnormal blood vessel growth or deposits of decayed tissue that are the cause macular degeneration symptoms like blurred central vision.

An Amsler Grid Test is a test where your doctor has you look at a black and white grid with a small black dot in the center. While people with clear vision see straight lines and a small dot, people with the disease look at it and see distorted lines as if the grid has been twisted and has a very large hole in the middle of it.

After you have undergone pupil dilation and the Amsler Grid macular degeneration tests, there are more comprehensive macular degeneration tests your doctor may order. One of these is called a fluorescein angiogram, which is a procedure where special dye is injected into your arm so it can quickly circulate through your bloodstream. After the dye travels to your eye, which only takes a few seconds, a special camera can be used to see if there are blood leaks near your retina. If there are, then your eye doctor will be able to conclusively diagnose you with wet macular degeneration.

It is very important to have macular degeneration tests conducted as soon as you notice the first signs of the disease. This is because some preventative macular degeneration treatments exist that can help you maintain your vision and slow the progression of the disease. If you have wet macular degeneration, you may even be able to have laser surgery that destroys the abnormal blood vessels causing your blurred vision so you can make a full recovery. Once the disease has progressed beyond surgery, however, there are not many macular degeneration treatments that can help you except for special low vision aids like magnifiers, reading glasses, telescopic glasses and electronic aids.
