Sight Savers International - Saving Sight - River Blindness
Information about the disease and its treatment.
http://www.sightsavers.org.uk/html/savingsight/treatments/river.htm

Extractions: River Blindness is another name (coined by Sight Savers' founder Sir John Wilson) for a disease called onchocerciasis. As well as being a major cause of blindness in West and Central Africa, it is also present - to a lesser extent - in the Arabian Peninsula and the Americas. At the moment about 18 million people are infected, of whom roughly 300,000 are irreversibly blind. Astonishingly, a huge 125 million further people are currently at risk from infection. As well as causing blindness, onchocerciasis also has several other, equally harmful, effects. People who suffer from it will experience skin conditions such as 'nodules' (bizarre protuberances) and terrible itching, causing them to scratch repeatedly. This results in damage to the pigment and over time the skin becomes mottled; a distinctive characteristic of the disease known as 'Leopard Skin'. This can cause further problems because the de-pigmented 'spots' are more susceptible to skin cancer. Also, because the layers of skin just under the surface are damaged by the disease, it gives the appearance of premature aging ('Lizard Skin'), which can be especially damaging for younger sufferers. Because it becomes endemic in certain areas, it also has two important social implications:

This can result in decreased peripheral vision and, eventually, blindness. Glaucoma is similar to ocular hypertension but with accompanying optic nerve damage and vision loss. Glaucoma affects an estimated 3 million Americans, with 120,000 blind due to the condition. Elsewhere in the world, treatment is less available, and glaucoma ranks as a leading cause of blindness just about everywhere. Even if people with glaucoma do not become blind, vision can be severely impaired.

Extractions: Read the June bulletin. WCB is the umbrella body for visual impairment in Wales. It is an independent organisation for Wales. Our membership consists of organisations concerned with visual impairment. We are unique in having both statutory and voluntary organisations in membership - local authorities and all voluntary groups working in this field in Wales including branches or representatives of U.K. bodies. The aims of WCB as outlined in its constitution are to promote the welfare of blind and partially sighted people and the prevention of blindness We work to get visual impairment on every agenda. We believe that policies and services should be based on increasing independence and empowering an individual to make their own decisions and organise their own lives. It is uniquely easy to network in Wales and to develop a strategic approach for this purpose because of its size and culture. We believe too that visual impairment should be part of the mainstream and that skills and information should be shared.

http://kidshealth.org/kid/talk/qa/color_blind.html

Extractions: To understand what causes color blindness, you need to be cool with cones and what they do. No, not ice cream cones! We're talking about the cones in your eyes . At the very back of your eye is the retina. It's about the size of a postage stamp, and it contains millions of cells that are sensitive to light. Some of these cells are called cones. Cones let you see color by combining the three main colors (red, blue, and yellow) to make thousands of colors, from the orange of your macaroni and cheese to the turquoise of a tropical fish. Even though many people think that being color-blind means a person can't see any color, this isn't true. Very few color-blind people see life the way it is on an old black-and-white TV show. Instead, most people who are color-blind just have a hard time telling the difference between certain colors. If you don't have the correct chemicals in the cones, they may not let you see the right number of main colors. Most people who are color-blind aren't able to see red or green. For example, when a kid who is color-blind looks at a green leaf, he sees a leaf that's either a neutral color (like a light tan) or a shade of gray. Is Color Blindness Inherited?
Face Blind! Bill's Face Blindness (Prosopagnosia) Pages - Introduction
A personal account of face blindness (prosopagnosia), by a sufferer.
http://www.choisser.com/faceblind/

Extractions: This is the world's first (and to date only) book about face blindness. It has been published on the Internet so people in all lands can have access to it readily, and so it can be continuously updated. In these pages, you will find information, much of which is not available anywhere else at this time. Until people with this rare condition began to meet each other on the Internet in mid-1996, assembling this kind of information would not have been possible. Even researchers who have had hopes of specializing in this condition have been frustrated by having seen only a handful of subjects over a lifetime. With the advent of the Internet, face blind people are coming together in heretofore unheard of numbers, and much is being learned with each passing month. This document was first published as "Bill's Face Blindness Pages" in January, 1997, based on information learned in the fall of 1996. Since then, it has grown considerably, to become the document you will now see. Face Blind!

http://www.internettg.org/newsletter/dec98/banner_blindness.html

Extractions: Rice University Suppose you are designing a web page where one particular link among many is likely to be the most used by visitors. For example, perhaps you have a web page for sending text messages to pagers. "Send a message" is likely to be a very popular link, and it is important that all users notice it. On a travel reservations page, the designer wants to be sure that users notice the link for "make a reservation." Web guidelines usually recommend that to make an important item stand out, it should be near the top, and be large and/or brightly colored. For example, the Ameritech web design guidelines state: "In general, the larger an item is, the greater its perceived visual importance and likelihood of attracting attention. Make sure that items of greatest importance are easy to see, and clearly distinguished from other items. (Detweiler & Omanson, 1996)" Although this seems like perfectly good design advice, we have reason to believe it may not be. In a usability test of a corporate intranet, we were interested in finding out whether the novice users could make their way easily from the main home page to a lower-level page on computer training courses. We gave the users the task of finding information about Internet courses. The training page contained the seemingly highly-salient link shown below.

Extractions: The National Vision Research Institute was founded in 1972 to pursue research in vision and the disorders of vision. It devotes the whole of its resources to research and is therefore able to embark on investigations of difficult problems which require intensive and co-ordinated basic and clinical research over a long period of time. Its goal is the preservation of sight and the prevention of blindness. The NVRI is currently undergoing a restructure that has resulted in significant changes to staff and research projects. At this stage the web pages are unavailable while they are updated. They will be updated over the next few months. Vision testing products are still available for purchase from the NVRI.

Color Blindness - Color Vision
Color blindness may be a hereditary condition or caused by disease of the optic nerve or retina. Color blindness. Complete color blindness is very rare.
http://www.stlukeseye.com/Conditions/ColorBlindness.asp

Extractions: Color Blindness Overview Color blindness may be a hereditary condition or caused by disease of the optic nerve or retina . Acquired color vision problems only affect the eye with the disease and may become progressively worse over time. Patients with a color vision defect caused by disease usually have trouble discriminating blues and yellows. Inherited color blindness is most common, affects both eyes, and does not worsen over time. This type is found in about 8% of males and 0.4% of females. These color problems are linked to the X chromosome and are almost always passed from a mother to her son. Color blindness may be partial (affecting only some colors), or complete (affecting all colors). Complete color blindness is very rare. Those who are completely color blind often have other serious eye problems as well. Photoreceptors called cones allow us to appreciate color. These are concentrated in the very center of the retina and contain three photosensitive pigments: red, green and blue. Those with defective color vision have a deficiency or absence in one or more of these pigments. Those with normal color vision are referred to as trichromats. People with a deficiency in one of the pigments are called anomalous trichromats (the most common type of color vision problem.) A dichromat has a complete absence in one cone pigment.

Color Deficient Vision
Color blindness references for Web Designers. Cards and Charts simulating the websafe colors in color blindness. Highly recommended. Tests For Color blindness.
http://www.visibone.com/colorblind/

Extractions: simulations Toward the lower left on the Card and the Chart is a simulation of deuteranopia , a common variety of color blindness. This is from the Greek for "second doesn't see" referring to the second cones in the retina of the eye that respond primarily to green light and are presumed to be defective in this condition. This doesn't mean that greens are invisible to people with deuteranopia. Human vision is complicated. The role of the green cones is less to detect green light than to distinguish it from red. Similarly, when the red cones "don't see" (protanopia), the main consequence is that reds, yellows and greens are indistinguishable. This figure simulates the web-safe colors as they appear in a deuteranopic condition. In most other categories of color blindness, protanopia, protoanomaly and deuteranomaly, the view is very similar but there are subtle differences. In one very rare form, called tritanopia, affecting thirty people in a million, colors appear very differently. The

Extractions: The patient had great difficulty pouring coffee into a cup. She could clearly see the cup's shape, color, and position on the table, she told her doctor. She was able to pour the coffee from the pot. But the column of fluid flowing from the spout appeared frozen, like a waterfall turned to ice. She could not see its motion. So the coffee would rise in the cup and spill over the sides. More dangerous problems arose when she went outdoors. She could not cross a street, for instance, because the motion of cars was invisible to her: a car was up the street and then upon her, without ever seeming to occupy the intervening space. Even people milling through a room made her feel very uneasy, she complained to Josef Zihl, a neuropsychologist who saw her at the Max Planck Institute for Psychiatry in Munich, Germany, in 1980, because "the people were suddenly here or there but I did not see them moving." The woman's rare motion blindness resulted from a stroke that damaged selected areas of her brain.

LOS ANGELES, California (Reuters) - An experimental drug that blocks abnormal blood vessel growth in the eye is an effective treatment for the leading cause of age-related blindness, according to research unveiled Saturday. Macugen, a drug being developed by Pfizer Inc. and Eyetech Pharmaceuticals Inc., was 27 percent more effective than placebo at limiting vision loss in patients with the "wet" form of macular degeneration in a late-stage trial, said Dr. Carmen Puliafito, director of Bascom Palmer Eye Institute in Miami and the study's lead investigator. In macular degeneration, the central and most important area of the retina the macula deteriorates. The more common "dry" form results in gradual vision loss. In the more serious, wet form of the disease, vision loss occurs quickly as blood vessels leak and form a mound. The mound later contracts, leaving a scar that blocks vision. This form of macular degeneration afflicts an estimated 1.2 million Americans and the incidence is expected to rise as baby boomers age.

Vision Impairment (part 1), NCBDDD, CDC
blindness is defined as a visual acuity worse than 20/400, with the best possible correction, or a visual field of 10 degrees or less.

Extractions: NCBDDD Home Vision Impairment What Is Vision Impairment? How Common Is It? ... Click here to contact the National Center on Birth Defects and Developmental Disabilities. What is vision impairment? Vision impairment means that a person's eyesight cannot be corrected to a "normal" level. It is a loss of vision that makes it hard or impossible to do daily tasks without specialized adaptations. Vision impairment may be caused by a loss of visual acuity, where the eye does not see objects as clearly as usual. It may also be caused by a loss of visual field, where the eye cannot see as wide an area as usual without moving the eyes or turning the head. There are different ways of describing how severe a person's vision loss is. The World Health Organization defines "low vision" as visual acuity between 20/70 and 20/400, with the best possible correction, or a visual field of 20 degrees or less. "Blindness" is defined as a visual acuity worse than 20/400, with the best possible correction, or a visual field of 10 degrees or less. Someone with a visual acuity of 20/70 can see at 20 feet what someone with normal sight can see at 70 feet. Someone with a visual acuity of 20/400 can see at 20 feet what someone with normal sight can see at 400 feet. A normal visual field is about 160-170 degrees horizontally. Vision impairment severity may be categorized differently for certain purposes. In the United States, for example, we use the term "legal blindness" to indicate that a person is eligible for certain education or federal programs. Legal blindness is defined as a visual acuity of 20/200 or worse, with the best possible correction, or a visual field of 20 degrees or less.

Extractions: Alifano, Roberto. E l tema de la presente investigación es la ceguera en la obra lírica de Jorge Luis Borges. Nuestro corpus está constituido por cinco sonetos: On his blindness (OHB1) de El oro de los tigres El ciego I (EC1) y El ciego II (EC2) publicados en dos volúmenes, El oro de los tigres y La rosa profunda Un ciego (UC) de La rosa profunda On his blindness (OHB2) de Los conjurados Consideraremos solo parcialmente el Poema de los dones (PD) de El hacedor (1960) y Elogio de la sombra (ES) de Elogio de la Sombra (1969), ya que, por razones métricas, temáticas y estilísticas creemos que los sonetos forman un todo homogéneo y que, si bien estos dos poemas antes mencionados comparten núcleos temáticos, son más las divergencias que las convergencias que presentan con el resto de los textos del corpus. Todos los poemas sobre la ceguera fueron compuestos a partir de 1955, es decir, que no incluimos en este análisis ningún texto de sus primeros tres volúmenes poéticos.
