This test might be utilised by ophthalmologists and optometrists, to identify patients with a high genetic risk of developing AMD but without any clinical signs of disease.

Scientists have developed a new technique, which they claim will help detect healthy people at risk of developing age-related macular degeneration (AMD), one of the leading causes of blindness worldwide.

Using standard clinical techniques, the detection of AMD has previously not been possible in the disease’s early stages. Doctors tend to diagnose AMD once small changes become visible at the back of a patient’s eye. However, degeneration begins many years before these clinical signs appear.

Now, a team at Queensland University of Technology, led by eye specialist Dr Beatrix Feigl, has come up with the “dim light vision” test which, it says, is very sensitive to early changes in a person’s vision.
