1. Improving Peripheral Vision Through Optical Correction and Stimulus Motion
Sammanfattning : The loss of central vision subsequent to macular disease is often extremely debilitating. People with central field loss (CFL) must use other peripheral areas of the retina in order to see; areas with inferior resolution capacity, which are also affected by off-axis optical errors.

2. Eccentric correction in central visual field loss
Sammanfattning : It is not often that one is instantaneously able to apply the results of basic research. This work is an example of such an exception. A widely held conviction has been that human peripheral vision could not be improved through optical correction. It w. LÄS MER
3. Optics for Low Vision Enabling
Sammanfattning : For people with central visual field loss, eccentric vision is all that they have to rely on. Even for those who learn how to correctly utilize their eccentric vision, it will never be as good as the central for two entirely different reasons: the off-axis optics of the eye can result in large refractive errors, and the low function of the peripheral retina.

4. Optimal Use of Peripheral Vision
Sammanfattning : People who lose their central vision have to rely on their peripheral vision for all visual tasks. The ability to resolve fine details in the periphery is reduced due to retinal limitations and the optical aberrations arising from the use of off-axis vision. LÄS MER
5. Tendon transfer mechanics and donor muscle properties : implications in surgical correction of upper limb muscle imbalance
Sammanfattning : Tendon transfer surgery is used to improve the hand function of patients with nerve injuries, spinal cord lesions, cerebral palsy (CP), stroke, or muscle injuries. The tendon of a muscle, usually with function opposite that of the lost muscle function, is transferred to the tendon of the deficient muscle. LÄS MER
