People with the eye disease called age-related macular degeneration must often contend with a blank or fuzzy spot at the very focus of their vision. Researchers have now developed a rehabilitation regime that may enable many elderly people with the disease to get around this impediment.
Previous attempts at such vision retraining haven't been standardized and properly tested, says Janet P. Szlyk, a psychophysicist at the University of Illinois at Chicago College of Medicine. These therapies may partially restore reading ability in some patients, Szlyk says, but there's little evidence to suggest they improve other aspects of vision.
