Scientists from China and Australia have conducted a study and named a sign that allows you to determine how much a person is prone to early death. The findings of the study were published in the British Journal of Ophthalmology.
Experts have found that if the retina begins to age prematurely, it can be a sign of a short life in general, as well as an early death. For 11 years, researchers have observed the state of the retina of 36,000 people aged 40 to 69 years. During this time, 1871 people died. The cause of death for the largest number of them was cancer. They were found to have “rapidly aging” retina – its condition did not correspond to their biological age.
Scientists explained that such problems arise due to damage to its nerves, as well as blood vessels. Such effects can be caused by a number of factors, such as hypertension, high blood sugar and cholesterol levels, malnutrition, or obesity. In this case, an unhealthy shape of the retina is a reflection of health problems that are not always visible, reports the Medic Forum.
If a person's retina is a year older than his actual age, the risk of death from any cause increases by two percent. The big difference between the age of a person's retina and his actual age means an increase in such risk from 49 to 67 percent, the experts concluded.
