Some drivers with glaucoma overcome visual field loss by increasing scanning

Postby akirk » Wed Oct 28, 2015 9:59 pm

An interesting article here:
http://www.medicalnewstoday.com/articles/301647.php
about drivers with eyesight issues who can overcome them...

The researchers also took measures of the drivers' eye and head movements. They compared these with their performance on the test.

Three of the six participants with glaucoma passed the driving test, and their performance was no different from that of the participants with normal vision.

However, the glaucoma drivers who passed the test showed increased visual exploration - they made more head and eye movements - than the glaucoma drivers who did not pass. The drivers who passed the test also had a tendency for shorter fixation times and more fixations per minute. Dr. Kasneci notes:

"Such behavior indicates an increased scanning activity in glaucoma patients who passed."

Ta for this. A friend is visiting over from France for a few days, so just printing the article for him.

His PhD was on the effects of ageing and brain injury causing partial loss of vision and the adverse effects on driving, so this overlaps.
My own views. For better or worse :)
