Eye device "could detect brain tumours"

Eye device "could detect brain tumours"

By Adrian Galbreth

Problems with peripheral vision can be an indicator of brain tumours, and now scientists have developed an eye device to detect such illnesses.

Researchers in Edinburgh have designed a device which uses infra-red light to measure peripheral vision.

Problems with peripheral vision have been known to indicate brain tumours, brain damage and strokes, as well as other conditions that can lead to blindness.

Machines which are currently in use to test peripheral vision rely on the individual pressing a button in response to lights, and sitting very still for several minutes, meaning that around 30 per cent of the population cannot use these.

However, the new i2eye device uses intra-red LEDs and a camera to record eye movement, so it can be used on far more people, including children.

Professor Robert Minns at the University of Edinbugh, told BBC News: "All we have been able to do is sit in front of [children] and try to see where we think they can look. This system uses a child's natural inquisitiveness."
