Extractions: Retinitis Pigmentosa var site="sm5retinitis" An overview of retinitis pigmentosa (RP) Retinitis pigmentosa is a group of hereditary diseases that causes the degeneration of the retina. Often called night blindness, retinitis pigmentosa may develop in a family where either one parent or both parents are affected or where there is seemingly no familial history of the disease. In other cases, RP is observed in only the males of the family. Typically, symptoms start in childhood and early adolescents. They include decreased ability to see in dim light such as movie theaters or ball games, night blindness and bumping into or tripping over objects. There may also be loss of color vision and the inability to focus or see objects in detail. The symptoms experienced depend entirely on the type of retinitis pigmentosa. Long-term affects of RP include so called 'tunnel vision'. This loss of peripheral vision is usually gradual, reducing the visual field to a narrow area of the eye, directly in front of the individual. In many cases, people with retinitis pigmentosa are considered 'legally blind' by the time they're 40. In cases where retinitis pigmentosa and hearing loss or deafness occur, there is a chance of Ushers Syndrome. Ushers Syndrome is an inherited disease affecting 3-6 % of the deaf and is usually diagnosed in childhood.

Filed under: Web Standards Keyword Tags: standards lifelong+learning web+best+practice I had heard of table-less design before, but had tried it and found it to be very difficult with very little benefit. It made my job twice as hard and took 3 times longer. I gave up quickly. One of the biggest obstacles was understanding how floats work. After hearing Zeldman, Bowman and Molly H. evangelize us on the benefits of said approach and watching it DEMONSTRATED I started to realize just how important table-less design can be. It also revealed that it was not that difficult to acheive. All that added up to a big wake-up call for me.

Beginning PREVIOUS Before getting into the details of the types of color-blindness, you should know that the following explanations are simplified versions of the complete picture. Color-blindness is a fascinating topic precisely because of its complexity. You do not need to understand all of the details of color-blindness to know how to create Web content that is accessible to those who are color-blind. Here is an important fact to understand right off the bat: The overwhelming majority of people who are color-blind can see colors. They just have difficulty distinguishing between certain colors. The colors with which they have difficulty distinguishing depend upon their type of color-blindness, but red-green deficiencies are the most common. The most common broad category of color-blindness is often called red-green color-blindness , but this does not mean that these people cannot see reds or greens. They simply have a harder time differentiating between them. Not all reds and greens are indistinguishable. It would be easy for someone with a red-green deficiency to tell the difference between a light green and a dark red, for example. A lot dependsat least in parton how dark the colors are. If the red is approximately as dark as the green, there is a greater likelihood that the colors will be confused.

Last Updated Tue, 26 Jul 2005 16:09:08 EDT CBC News Men who take drugs for erectile dysfunction should see a doctor immediately if they experience sudden vision loss or problems, Health Canada warned Tuesday. The erectile dysfunction drug Viagra is linked to blindness and vision problems, the department said. "There are two cases that have some commonality but we are still pursuing further information," said Barbara Raymond of Health Canada's Marketed Health Products Directorate. "In fact, we may ultimately find that neither of those cases truly represent the condition that we're concerned about." FROM MAY 27, 2005:

A Philosophy Of Blindness Whether we think about it or not we all have a philosophy of blindness. So here are some discussions about different aspects of blindness, http://www.blind.net/bphiloso.htm
Extractions: A Blind Net A Philosophy Of Blindness At first glance it might seem strange to have a section about a philosophy of blindness, however I think it is an extremely important topic to cover. The reason is simple, how you view blindness will determine your reaction to being blind or to those of us who are blind. There are as many ":philosophies" of blindness as there are people so obviously I won't be trying to cover EVERY point here. What I want to do is present you with some ideas about what blindness is, a positive outlook if you will, and thereby let you know what blindness DOES NOT NEED TO BE. Whether we think about it or not we all have a philosophy of blindness. It determines how we treat blind people and how we think about ourselves if we are or become blind. Of course one question to answer is who is blind ? Then there's the ":sensitive": question of what do you call someone who is blind ? My short answer would be blind, but God help us some people are offended by that "nasty five letter word." So here are some discussions about different aspects of blindness, incidents that have happened to blind people and the affects of different philosophies of blindness.

All RSS Feeds By Marc Kaufman Washington Post Staff Writer Friday, July 1, 2005; Page A02 More than 13 months before a scientific journal reported that Viagra had been linked to a rare form of blindness in some men, a Food and Drug Administration safety officer made the same observation from monitoring adverse event reports and told her supervisors that doctors and patients should be warned of the findings. Her recommendation was well received, she told congressional investigators, but nothing happened. The FDA issued no public notice or proposed changes to the Viagra label. That came only following widespread publicity last month about the journal article and public concerns about the possible blindness-Viagra link.
Extractions: CNET tech sites: Track thousands of Web sites in one place: Newsburst July 27, 2005 5:03 PM PDT To most people, becoming an expert at video games like "Mortal Combat" takes hours of practice and a sharp eye. But Brice Mellen, a 17-year-old from Lincoln, Neb., routinely knocks off opponents even though he's at a slight disadvantage. He's blind. The Associated Press reported Wednesday that Mellen, who was born blind as a result of Leber's disease, became a game whiz through years of carefully memorizing key combinations, joystick movements and other in-game strategies. Having cut his teeth on "Space Invaders," Mellen is now the alpha "Soul Caliber 2" player on his block. After high school, he says, he plans to go to college and major in, naturally, video game design. Posted by Daniel Terdiman TalkBack Post a comment
