Computer based visual search DVD

A DVD of a computer based visual search technique has been made by the Oxford University Oculomotor Group.  The image below shows the sort of visual search task which is involved.  People are required to search for a target object amongst distractors using their eyes while keeping their head still.  Training results in increased search speed, reported improvements in daily vision, and improvements in tasks representing activities of daily living.

Contact Dr Stephen Hicks at Oxford University for more information.

The technique was published in the Journal of Neurology, Neurosurgery and Psychiatry in 2004.  For a PDF of the publication from PubMed Central, follow this link:

Here's an interesting clip of Rochester University's Krystel Huxlin talking about a visual rehab method they're developing, published in the Journal of Neuroscience last year.

Vision screening in stroke

Vision screening in stroke is included in the new Scottish Intercollegiate Guideline Network (SIGN) Guidelines.  Screeing, if possible by an orthoptist, is recommended.  However, it has not yet been shown the screening is effective in terms of patient outcomes like visual function, falls, quality of life, though according to a recent study the vast majority of patients referred to orthoptists do indeed turn out to have visual problems of one sort or another.
