Sydney: A powerful new technique, developed by scientists, can quantify damage caused by serious eye diseases affecting tens of millions worldwide.
"We`ve known for a century or so that the pupil reacts more to a stimulus on one side of the visual field than the other, though we did not know how or why until recently," he said. "In our research we have been trying to localise the responses of the pupil to particular places across the visual field and hence, the eye`s retina," said Maddes, according to a release of the Vision Centre. By mapping places where the response of the retina is patchy and the pupil responds less strongly, the team has been able to detect portions of the retina affected by the disease and so improve the chances of early accurate diagnosis and treatment of a condition which in many cases may result in loss of vision or complete blindness.
