Scientists have claimed that eye tests could be used to detect Alzheimer's disease among the elderly people. The research was carried out by the Australia's Commonwealth Scientific and Industrial Research Organization and involved 126 people. The research was presented at the at the American Alzheimer's Association International Conference in Paris on Sunday.

Previous researches carried out by the researchers from the University College London have found that some differences can be spotted in the retinas of dementia sufferers, which can help in early diagnosis of the degenerative brain condition.

The Chief Executive of Alzheimer's Research UK, Rebecca Wood, said, "This study adds to previous work suggesting that eye scans could be a useful aid for diagnosing Alzheimer's disease, these results could lead to a simple and effective method of detecting Alzheimer's at a much earlier stage".

This recent research would open new avenues for the detection and treatment of Alzheimer's disease, which has affected 820,000 people in the UK.

At present, memory tests or brain scans are used to detect the early signs of dementia but recently, the scientists have started studying the light-sensitive layer at the back of the eye to look for damage, which can help in detecting dementia.
