By Veit Peter Gabel

This publication provides and analyses the newest learn devoted to restoring imaginative and prescient in people who are significantly impaired or blind from retinal illness or harm. it really is written by means of the major teams around the world who're on the vanguard of constructing synthetic imaginative and prescient. The e-book starts by means of discussing the problems in evaluating and reading useful leads to the world of very low imaginative and prescient and the significant customers and barriers of spatial solution with man made instruments. extra on, chapters are integrated through researchers who stimulate the skin or the pigment epithelial aspect of the retina and by way of specialists who paintings on stimulating the optic nerve, the lateral geniculate physique and the superficial layers of the visible cortex.

Artificial imaginative and prescient: A medical consultant collates the newest paintings of key synthetic imaginative and prescient learn teams to give an explanation for in a similar and stringent order their various ways, the medical or preclinical results and their achievements over the last years. Senior ophthalmic fellows and educational practitioners will locate this advisor to be an quintessential source for knowing the present prestige of synthetic imaginative and prescient.

Example text

The use of subscales can certainly be informative for clinical application of PRO instruments, but the interdependence of subscales limits their use for research purposes, as it would be inappropriate to use more than one subscale as an outcome measure. Well-designed PRO instruments therefore tend to avoid the use of subscales. While the use of subscales has been limited to clinical studies, research in the area of visual impairment and low vision rehabilitation has widely accepted the assignment of activities to four separate visual domains: reading (more broadly defined as detail vision), visual information gathering, visually guided mobility, and visually guided activities (often called eye-hand coordination).

Sommerhalder and A.
