Eye Training For Better Seeing
September 9th 2009 -
A computer-based visual training can help humans after an apoplexy to orient itself better in their environment. That resulted in a current study of Tubingen of opticians. The results are published in the “magazine for practical eye medicine 2009 (in the pressure).
After a brain damage suffer up to 40 per cent of the patients under a visual disturbance. With many parts of the visual field fail, them go blind half laterally. The researchers let the patients a so-called “Saccades training” go through – they practiced jerky movements of the eyeballs. Thus the patients learned to arrange their attention also on things not to see “them actually can”, describe Professor Susanne Trauzettel Klosinski of the university University of T5ubingen.
On a Notebook screen small numbers in coincidental consequence, which away-click the patients with the mouse of the computer, appear. Some numbers appear also in the blind face half. “The patients learn soon to find it to assistance of the Saccades”, say the eye lady doctor. The participants trained five days per week twice daily for 30 minutes each. After six weeks training shortened the response time, and the test persons discovered also things in the blind half of the visual field faster. It succeeded to the trained one in addition faster to take up with other humans view contact. Also six weeks after training end were still present the positive effects. The neurological damage did not let itself repair, but the remaining field of vision would let itself use more effectively and increase functionally, so the eye lady doctor.
A visual field loss leads to impairments in the everyday life. The patients trip over chairs, waste-paper baskets or other obstacles, collide with humans and endanger themselves and others in the traffic. Reading is impaired strongly, most becomes work unable.
