Researchers continue to search for methods of preventing and treating blindness. A new study in the Journal of Archives of Ophthalmology shows that a single serving of fish per week is associated with a reduced risk of incident early age-related macular degeneration, a disease that is the leading cause of severe vision loss in people older than 60. The macula, a part of the retina that allows central vision, deteriorates in this condition.

Dr. Marc Maurer, President of the National Federation of the Blind, addressed staff at the Library of Congress today focusing on the need for digital information to be made available to the blind. Peter Lane, 51, is one of the first people in the world to have electronic receivers implanted into his eye which send signals mounted in a pair of glasses to the brain. The technology has allowed Mr Lane, from Manchester, to see the outline of objects, such as doorways and furniture, and to read letters through a series of dots of lights for the first time in almost 30 years. Blind for nine years, Sharron “Kay” Thornton has just regained her sight through a procedure implanting an eyetooth in her eye, as a base to hold a prosthetic lens. Talking Books Int., Inc. has developed the latest version of the Talking Bible for people who are blind, visually impaired or reading impaired. The world is becoming more digital these days. Almost every technology needs a person TO SEE some kind of visual display. That drives a blind man crazy! Three patients had their sight restored in less than a month by contact lenses cultured with stem cells. All three patients were blind in one eye. The researchers extracted stem cells (non embryonic) from their working eyes, cultured them in contact lenses for 10 days, and gave them to the patients. Within 10 to 14 days of use, the stem cells began recolonizing and repairing the cornea. There are two methods to mass-produce Braille documents; one is embossed Braille and the other is pressed or plated Braille. It’s a common misconception that pressed Braille is the only method for large volume Braille runs; the emergence of high-speed embossers has put an end to depending on pressed Braille. Studies have been done showing that only ten percent of blind children are taught Braille. I can tell you this that when my children who are sighted went to school if they were not taught how to read and write, I would have been in the school office demanding that the practice of not teaching reading and writing be changed. |
