The macula allows the retina for the treatment of small details. If the macula is damaged, clear central vision and the ability to see detail is lost.

Types of macular degeneration

There are two types of degeneration macularechiamato dry macular degeneration, wet macular degeneration. The dry form of the disease is far Conseitet. Approximately 85-90% of all macular degeneratien circumstances. Dry macular degeneration results from the slow distribution of cells of the macula, leading to progressive loss of central vision. Wet macular degeneration consists of only 10-15% of cases, but is heavier and more rapid progression of the disease. DepressioneWet macular générescence is caused by deterioration of the retina to the flow or dexígekeine zone and results in cracks or columns of the retina. The bodyr respond by creating new blood vessels in the retina bueyygen. These vessels are fragile and the loss of blood and tears in the retina, so that your name. In addition to the loss of fluid into the retina, blood vessels to travel the macula, the pressure on them, just like the roots of trees can be from a sidewalk.

Macular DegenerationStatistiques - United States and Canada

Although wet macular degeneration is a relatively small number of cases,the reason for the vast majority of macular degeneration, with loss of vision. According to a study published in 2004 in the Archives of Ophthalmology, 1.75 million Americans suffer from this condition, and the number should be limited to 3 million by 2020, the U.S. population continues to grow. Overall, about 2% of estadounidense at least 60 years to develop the terms of ions, and the risk increases to 30% in general, the possibility of development of the Krankheit of Americans older than 75 years. In Canada, the prevalence is even greater, with a surprising 23% of Canadians aged 43 or T64 development of the disease. True to its name, the incidence of macular degeneration increases to 56% of Canadians aged 65 to 84 years.
