TUESDAY, April 14 – Although the rate of age-related macular degeneration is on the increase, newer treatments could help reduce the most serious effects of the disease by about 35 percent, new estimates suggest.

Neurons seem to want to receive input: When their usual input disappears, they start responding to the next best thing," senior author Nancy Kanwisher, of MIT's McGovern Institute for Brain Research, said in an university news release.

That's the conclusion of a new study that challenges the findings of several large epidemiological studies that suggested a link between cataract surgery and accelerated AMD progression.
AMD and cataracts are leading causes of vision impairment in the United States. Both are related to aging and share other risk factors. AMD affects the retina and leads to loss of central vision. Cataract is cloudiness in the eye's lens that interferes with clear vision. Read more...
