People who take aspirin increase their risk of vision loss in later life
According to The Daily Telegraph report people who take aspirin frequently increase their risk of loss vision twice in later life. An international study of over 4,000 elderly people found that daily aspirin users are twice as likely to be diagnosed with a late-stage form of age-related macular (AMD) degeneration is a common cause of vision problems in older people.
During the research examined the association between aspirin use in older people and AMD. To find out the relationship, researchers tested the eyes of 4,691 adults aged over 65. They also assessed their aspirin use and other medical and lifestyle factors. The researchers found that people who took aspirin daily were more than twice as likely to have a more severe, later stage of AMD. This is known as “wet” AMD, and about 15% of people with AMD develop it. However, the relationship between aspirin use and other stages of AMD was not consistent, with aspirin users being no more likely to have mid-stage AMD.
As study resulted that AMD and aspirin use at the same time, it cannot show that regular aspirin use causes or increases the risk of vision problems. So we cannot tell whether aspirin use or vision problems came first. On the evidence provided by this particular study, it is not possible to tell how or whether the two are related, or if some unaccounted for factor is linked to both aspirin use and AMD. For example, aspirin is often prescribed to people with cardiovascular problems, which are themselves associated with smoking and obesity. Both of these can be risks factors for AMD.
