Eye health can predict mortality risk in elderly
Eye health that declines when someone ages is actually not uncommon. All human beings will decrease the ability of the five senses as they age, one of which is the ability of sight. But a study suggests that the health of the eye not only due to aging process, but also can indicate the risk of death in the elderly.
These results were obtained after researchers surveyed about 2,500 people aged 65 to 84 years. Researchers observed once every two years for eight years. They found that eye health that is declining and loss of vision capabilities in the elderly are associated with greater risk of death.
Although this study did not indicate a causal link between the decline in eye health with death, but researchers have several theories related to eye’s health that has deteriorated and the ability of the elderly to survive, as reported by Healthy Living (8.21).
Researchers, led by Sharon Christ of Purdue University in West Lafayette, Indiana, believes that the problem of the worsening ability to see would give impact on the elderly daily life and their ability to perform daily work such as shopping, household routines, and others.
Seniors who have difficulty performing their daily work will increase risk of death to three percent within one year study period. In the eight-year study period, the risk increases to 31 percent higher than seniors who do not have problems with eyesight.
The study also found that older people who experience decreased vision one step at increased risk of death by 16 percent related to their inability to perform daily affairs.
According to the researchers, the results of this study can provide insight into the importance of maintaining eye health when one is already getting old. Elderly need to be more diligent in checking their eye health. Knowing problems with eye health would be better to prevent early. Currently, there are many ways to maintain the health of the eye, such as the use of glasses or other treatment.
