Medics will usually look at a patient’s ears to determine their hearing health, but this can’t detect early signs of the condition. A group of Canadian researchers believe that by observing eye movements, they can spot deafness far earlier
Someone’s stare tell doctors whether they will become deaf later in life, scientists believe.
Medical professionals usually observe the patient’s ears to identify deafness, but in most cases they can only detect the condition 10 to 20 years after it emerges. This is clearly unhelpful, so one team of Canadian researchers has stepped in, hoping they can detect the issues far earlier.
University of Toronto neuroscientist Dr Björn Herrmann believes he has found a clear indicator of hearing issues. In his study, he watched people’s eyes as they listened to someone talking and found those who struggled to hear, were staring more intently. This is partly supported by previous studies, in which people don’t move their eyes much while focusing.
Dr Hermann’s Journal of Neuroscience paper, which based its results on tests involving 23 young adults, has concluded that people who are struggling to hear have to put more effort in. This makes their eye movement fixate on a single point.
