With the help of artificial intelligence, eye scans can predict Parkinson’s disease, giving an average of seven years of warning, US researchers say. Moorfields Eye Hospital, London.
“This is the first time such findings have been shown several years before diagnosis,” said a hospital press release.
“This study demonstrates the potential of eye data to harness technology to capture signs and changes too subtle for humans to see. It opens up new possibilities,” added Alastair Deniston, an ophthalmologist at Moorfields.
The high-tech 3D scan (technically, optical coherence tomography) takes “less than a minute” to analyze a patient’s retina “down to 1/1000th of a millimeter,” the hospital said.
“The retina provides a minimally invasive window into the central nervous system and can be rapidly imaged using modern high-resolution devices.” researchers saidOn the other hand, “Detection of Parkinson’s disease by brain imaging is limited as a scalable resource.”
When it comes to eye examination, Parkinson’s disease is most associated with decreased thickness of two optical layers: the plexiform layer within the macular ganglion cells and the retinal nerve fibers.
“The association between retinal layer thickness and the development of Parkinson’s disease has not yet been investigated,” according to the published study.
“However, the findings in early and early Parkinson’s disease support our results,” the statement added.
Researcher Siegfried Wagner is simply “surprised” about the technology’s potential for detecting neurodegenerative disease.
“Although we are not yet ready to predict whether an individual will develop Parkinson’s disease, we hope that this method will soon be useful as a pre-screening tool for people at risk for the disease,” he said. Ta.
However, the technique doesn’t have to end there.
Similar advances can be seen in eye scans called “.Ophthalmologyhas enabled the rapid detection of other neurological diseases and disorders such as Alzheimer’s disease, multiple sclerosis and schizophrenia.
“Being able to detect the signs of many diseases before symptoms appear means that in the future, people will have time to make lifestyle changes to prevent any symptoms from occurring, and clinicians will be able to make life-changing decisions. It means we can delay the onset and effects of neurodegenerative diseases,” Wagner said. He said.
