CANBERRA<\/strong>\u00a0\u2013 Australian scientists have developed a blood test capable of saving millions of people around the world from going blind.<\/p>\n

Researchers from the Australian National University (ANU) on Wednesday revealed that their new blood test can detect patients at risk of dry age-related macular degeneration (AMD), a common disorder caused by damage to the macular that can cause blindness.<\/p>\n

The team, led by Riccardo Natoli from ANU’s John Curtin School of Medical Research, used a light model to study the deterioration of the retina’s photoreceptor cells in the macular.<\/p>\n

“The macular is the part of the retina that helps you see the grooves on your fingerprints.<\/p>\n

It is only 5.5 mm, so if an area equivalent to the size of a pin head starts dying — it renders you legally blind,” Natoli said in a media release on Wednesday.<\/p>\n

“Once that’s lost, there is no repairing it.<\/p>\n

“By looking at these photoreceptor molecules in the macular and understanding how they function, we will be able to early predict or diagnose a patient that is having systemic inflammatory responses.<\/p>\n

“Combined with predisposition genetic information, we hope to be able to predict people who are at high risk and start treating before the disease presentation even eventuates.”<\/p>\n

Current methods can take years to detect AMD, by which time, the damage is often irreversible.<\/p>\n

AMD can be treated with either vitamins and minerals or surgery if it is detected early enough.<\/p>\n

“The detection mechanisms we currently have for dry AMD happen too late,” Natoli said.<\/p>\n

“Once dry AMD starts there is a threshold tipping point and once a patient gets over that point there is nothing that can be done to save their sight.<\/p>\n

“By the diagnosis stage, you look at the back of the eye and you already see that photoreceptors, the light sensing cells of the eye, are starting to die.<\/p>\n
