Some say the eye are the window to the soul , but an Australian medical investigator says they are the windowpane to the heart and beyond .
Tien Wong of the Center for Eye Research Australia at the University of Melbourne has shown in several large - scale studies that abnormalities of the blood vessels in the retina can be used to predict patient ' risk of infection for diabetes , high blood pressure ( or gamy origin pressure ) , stroke andheart disease .
Window to the Heart: New Eye Exam Spots Diseas
These four disorders are some of themost common causes of dying , hospitalisation and handicap in the developed populace . But the power to foreshadow them is modified .
In plain sight

Wong ’s glide path involve psychoanalyse digital photographs of patients ' retinas and contemplate them to happen narrowing or ballooning of the belittled blood vessel . Systemic disease — those that affect several organs or the whole body — such as high blood pressure , diabetes , AIDS , Graves ' disease , lupus , coronary artery disease , multiple induration , creaky arthritis , and sickle cell anemia often cause changes in the eye that can show up as crimson battery-acid or small blood clots .
Inside the middle
descent vessels of the centre are so prognostic because they are part of the head ’s vascular system , so they share anatomical feature and react similarly to tension and disease , Wong tell .
In fact , oculus are so transparent compared to the eternal sleep of the body that they are the only electric organ that allow medico to directly see blood watercraft . The digital photography approach is non - invasive — no blood is accept , no incisions are made , no probes in orifices . It take just a few moment .
Wong has shown that retinal abnormalities are a good predictor of whether a patient will formulate eminent blood pressure or perish of cardiac disease in the next 10 years .
" My Bob Hope is that one day , retinal imaging will be able-bodied to provide an additional means to stratify risk of exposure and help identify people who may gain from early lifestyle change and preventive therapies , ” Wong toldLiveScience .
Eyes on the net
The melodic theme that the heart is a windowpane to the human body has been around for more than a century , but Wong has figured out how to make accurate and quantifiable predictions for unwellness base on retinal abnormalities that can be used as a touchstone by all Doctor of the Church .
Wong sees a future in which physicians admit retinal information in have intervention decisions . First , they ’ll need to arrive at a common categorization system for diagnosing retinal abnormalities .
How Heart Attacks Strike
Ultimately , Wong and his co-worker , who now are setting up a Retinal Vascular Imaging Center in Melbourne , plan to develop a Web - based system to which doctors can upload digital image of patients ' retina . The organisation will describe back the extent of a patient ’s cardiovascular disease .
It continue to be seen , though , how useful the system will be and with how many disease it may turn out helpful .
Emily Chew , a aesculapian researcher at the National Eye Institute in Bethesda , said she was not surprise by Wong ’s finding relating retinopathy with diabetes .
" It is important for all persons with diabetes to have regular eye exams ( every year ) and for those over 65 to have center exams on a yearly fundament to detect any eye disease that maybe treatable , Chew said in an e-mail interview .
However , Chew said eye test will pluck up only a small per centum of the population that have other systemic disease and " one would not shield with eye exams for systemic disease . ”
