Age: With the grow of age, the prevalence increased year by year, the possibility of more than 80-year-old elderly people suffering from AMD more than 40%. Genetic: If there is a family history of macular degeneration, it can happen at a certain age. Other factors: Macular degeneration can also be caused by high myopia and other eye inflammation. The study found that AMD is a eyes disease, that is, one eye suffering from AMD, and the other eye within five years the development of age-related macular degeneration probability of 40%.
What are the symptoms of AMD? AMD is divided into two forms of atrophy and exudation. Atrophic age-related macular degeneration is caused by the accumulation of metabolites of visual cells under the retina, which causes atrophy of the retina. Exudative age-related macular degeneration is caused by retinal neovascularization. These neovascular like cracked water pipes, are easy to leak and bleed, which can damage the macula and vision.
