An eye test to diagnose Alzheimer's disease could be on the horizon, after a Scottish company reported their test to be effective.
Eyecare specialist Optos said there was a "highly significant" link between Alzheimer's disease and alterations in the retina.
The screening test looked for tiny white or yellow spots on the retina known as drusen, to diagnose the condition.
Roy Davis, chief executive of Optos, said: "This latest study adds to a growing body of clinical data that supports our conviction that the optomap has a crucial role to play in the detection and monitoring of a number of diseases."
This follows the discovery of another test which could potentially diagnose Alzheimer's disease.
According to a study published in the Journal of Alzheimer's Disease, a unique biochemical diagnosis in the form of a blood test could be used to accurately detect which patients have the condition.
