As one grows older there are many changes that take place, some of which brings many problems to the individual. One of these complications is macular degeneration. This is a type of eye problem that effects a considerable number of people in the whole world. In America for example, this eye disease is estimated to affect almost 10 million people every year. This shows the magnitude of the problem. In fact, it is one of the major causes of loss of vision in people who are over 60 years old. It is believed that this condition increases with age and the oldest people are the most vulnerable. It comes in two forms i.e. Dry macular degeneration and wet macular degeneration.
Dry as well as wet macular degeneration begins by affecting your retinal tissues that provide central vision – the ability to see directly in front of you. This part is called macula. Once you contract this disease, your vision becomes blurred and you begin to experience frequent blind spots. This interference of your central vision makes it hard for you to read, cook, drive or perform your daily duties normally. Many people with a wet macular degeneration problem begin to feel that they want extra light in order for them to see clearly something they normally used to see in average light. They are therefore forced to bring the object such as a book close to the eyes for them to it clearly. Others use spectacles that improve their eye sights.
With wet macular degeneration, you start to see straight lines looking wavy or irregular. You also strain to see small objects or things that are a bit far from you. It is also possible for anybody suffering from wet macular degeneration to see things that are close to him appearing to be too far or much smaller than normal. However, the most common sign of this condition is losing the central vision. You may also experience frequent blind spots in your central vision.
Your macula is a combination of cells that are usually capable providing good central vision. They are also highly sensitive to light. These cells are kept alive by the blood supplied from underneath choroids. These choroids are very helpful to the macula since they are responsible for providing the necessary nutrients to the macula as well as removing waste products from macula. As you become older, these choroids are unable to transport the nutrients to your macula or even remove all the waste products from macula and hence your macula cells begin to die one by one. Your macula does not get enough blood since the choroids are too old to function properly and you may end up with a wet macular degeneration.
