Scientists have discovered that by examining people’s eyes, they can predict when they will die. According to a study, a machine learning model was developed to analyze individuals’ retinas, estimating ‘when they might die.’
Eyes Can Reveal Biological Age and General Health Status
Eyes, perhaps one of the most important of the five senses, possess more functions than previously thought. A scientific study published in the British Journal of Ophthalmology revealed that eyes can directly determine a person’s biological age and, consequently, their general health status. The scientists leading the research can calculate a person’s rate of aging and their biological age by examining the condition of their retinas.
Increased Mortality Rates Linked to Older Retinas
In the published study, a machine learning model was used to calculate biological age through the analysis of retinas. The algorithm had such a low margin of error that it was able to predict the biological ages of 47,000 middle-aged people in the United Kingdom. Of these 47,000 individuals, 1,871 have since passed away, and the majority of deaths occurred in the group with ‘older’ retinas.
Death Risk and Retina Age Relationship
If the algorithm determines that a person’s retina is one year older than their actual age, the likelihood of dying from any cause within the next 11 years increases by 2%. At the same time, the risk of dying from a cause other than cardiovascular disease or cancer also increases by 3%.
Retina Is Highly Sensitive to Aging Effects
This is a significant study, but its findings are still observational. Scientists cannot yet fully define the biological connection between retinas and life expectancy. The process works as follows: The retina is highly sensitive to the damages brought on by aging. As a result, the blood cells and nerves in the retina provide information about an individual’s brain and vascular health.
Past Studies on Eyes and Retina Aging
In the past, studies on eyes allowed scientists to predict various symptoms of aging, cardiovascular diseases, and kidney disorders. However, this study is the first to connect the retina with aging factors.
Retina Scanning and Future Applications
Retinas can be scanned in less than five minutes. If scientists can learn more about how this layer of tissue is connected to the rest of the body, doctors may have a powerful new diagnostic tool at their disposal.
Retina Scans for Early Diagnosis and Treatment
This method can be used in early diagnosis and treatment processes. Early detection of life-threatening diseases such as cardiovascular diseases and cancer is crucial for treatment success. Retina scans can detect the risk of these diseases at an early stage, potentially extending patients’ life spans.
Contributions of Retina Scans to the Healthcare System
Widespread and proper use of retina scans could provide significant benefits to the healthcare system. Early diagnosis and treatment can not only improve patients’ life spans and quality of life but also reduce the financial burden on healthcare systems.
Conclusion: Eyes Hold Critical Importance for Human Health
Eyes are not only crucial for vision but also provide essential information about human health. With this research, the impact of retina scans on human life expectancy and quality of life can be better understood. In the future, new studies and technological advancements are expected to further expand the applications of retina scans.
