Colour blindness linked to eye cells, not brain

Research undertaken by a team of scientists in Australia at The Vision Centre and The University of Sydney has suggested that colour blindness is in fact linked to eye cells rather than the brain.

Professor Paul Martin commented that in congenital or inherited colour blindness, the vision cells, or cone cells, are responsible for the condition rather than unusual biological wiring that exists between the eye and brain.

Colour blindness is the most common genetic disorder in humans, affecting around one in every eight males and one in 200 women.

He commented: "Now that we know faulty wiring isn’t the cause, we can concentrate on fixing the cones, which are controlled by genes – and thus prone to mutation or mistakes during cell replication."

This research could be the first step forward in being able to restore the full range of chromatic vision for people who have been born colour blind.ADNFCR-1853-ID-801454160-ADNFCR
