141. An Overview Of Retinitis Pigmentosa Information on night blindness, including the relationship between retinal degenerative diseases and the retina as well as basics on genetics and heredity. http://www.geocities.com/retinitis_pigmentosa_rp

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.

Key Concepts Types of Color-blindness 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. Red-green deficiencies 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.

144. 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

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.

Western Australian Retinitis Pigmentosa Foundation Fighting Blindness What is Retinitis Pigmentosa? Retinitis Pigmentosa is the name given to a group of diseases which affect the retina of the eye. The retina, located in the back of the eye, is the part of the eye that acts like the film in a camera. It is a delicate layer of cells which picks up the picture and transmits it to the brain - where "seeing" actually occurs. In RP, the retina begins to degenerate, which causes vision to diminish. One of the earliest symptoms of RP is difficulty seeing at night or in dimly lit places (night blindness). Later there is a reduction in side (peripheral) vision. The symptoms of RP generally increase over the years. It is known that certain cells in the retina, known as rods and cones, die in RP. The cause of cell death however, is not known at present, but research provides us with the opportunity to seek solutions. RP bodies throughout the world support research in a number of medical centres and hospitals internationally to find the cause, prevention and treatment of retinal degenerative diseases like Retinitis Pigmentosa, Usher syndrome and Macular Degeneration. Some of these centres also provide a clinical evaluation of the patient's RP or other retinal degenerations. They may also perform special tests requested by the patient's own ophthalmologist. Through the efforts of RP organisations in many countries, the number of highly qualified investigative scientists working full time on RP and related diseases continues to grow. Research efforts into these types of retinal diseases are difficult because there is no opportunity to safely biopsy - that is, remove and examine living retinal tissue under a microscope - the delicate eye.

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. Pfizer says it will add information to Viagra's label about possible links to blindness.

July 27, 2005 5:03 PM PDT Blindness doesn't stop game whiz 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.
