Achromatopsia Understanding Achromatopsia Richard L. Windsor, O.D., F.A.A.O. Laura K. Windsor, O.D., F.A.A.O. Published in Vision Enhancement Journal Achromatopsia is an inherited condition that affects approximately 1 in every 33,000 Americans. It is also known as rod monochromatism. This condition is associated with color blindness, visual acuity loss, extreme light sensitivity and nystagmus. It is a condition found throughout the world with varying incidence. There are two primary forms, the complete achromatopsia and incomplete achromatopsia. C omplete Achromatopsia A chromatopsia means “without color” and is defined as little or no function of the cone cells. Persons with achromatopsia are only able to perceive black, white and shades of gray. Patients with complete achromatopsia have no real understanding of the concept of color. A color like red may be perceived as dark gray while yellow may be perceived as a light gray. The vision is much like that of a black and white photograph with varying shades of gray. Incomplete Achromatopsia atients with incomplete achromatopsia have profound color impairment, but do have a small residual amount of color vision and slightly better visual acuity due to the presence of some functioning cone cells in the retina.

Cortical Blindness Cortical blindness - Alternative page for non-JavaScript browsers A presentation on visual field loss based on location of the injury in the brain Overcoming cortical blindness and brain-injury We have been blessed with a very special child, our son Sterling, 19 years old. Sterling was born blind and brain- injured due to a massive cerebral hemorrhaging (stroke) he sustained in utero or at birth. Doctors had told us that cortical blindness pertaining to the cortex area of the brain) is irreversible. Their prognosis was that our son would remain blind and a vegetable for the rest of his life.

Welcome to OnchoNET, the onchocerciasis information repository. Onchocerciasis is the second leading cause of blindness worldwide, affecting over 18 million people. From 1985 to 2000, the Edna McConnell Clark Foundation sponsored an international initiative to develop a vaccine for onchocerciasis, including the River Blindness Genome Project (RBGP) directed by Dr. Steven A. Williams (1995 to 2000). The RBGP is currently being funded by the A. K. Watson Trust (1999-2003). Now, the powerful research tools available on the Internet have been organized in OnchoNET.

124. William James - On A Certain Blindness In Human Beings On a Certain blindness in Human Beings William James. OUR judgments concerning the worth of things, big or little, depend on the http://www.emory.edu/EDUCATION/mfp/jcertain.html

On a Certain Blindness in Human Beings William James OUR judgments concerning the worth of things, big or little, depend on the feelings the things arouse in us. Where we judge a thing to be precious in consequence of the idea we frame of it, this is only because the idea is itself associated already with a feeling. If we were radically feelingless, and if ideas were the only things our mind could entertain, we should lose all our likes and dislikes at a stroke, and be unable to point to any one situation or experience in life more valuable or significant than any other. Now the blindness in human beings, of which this discourse will treat, is the blindness with which we all are afflicted in regard to the feelings of creatures and people different from ourselves. We are practical beings, each of us with limited functions and duties to perform. Each is bound to feel intensely the importance of his own duties and the significance of the situations that call these forth. But this feeling is in each of us a vital secret, for sympathy with which we vainly look to others. The others are too much absorbed in their own vital secrets to take an interest in ours. Hence the stupidity and injustice of our opinions, so far as they deal with the significance of alien lives. Hence the falsity of our judgments, so far as they presume to decide in an absolute way on the value of other persons' conditions or ideals. Commercial Advertiser

126. What Is Blindness? Legal blindness is visual acuity of not greater than 20/200 in the better eye with best correction or a visual field of less than 20 degrees. http://www.nib.org/blindness.htm

Legal blindness is visual acuity of not greater than 20/200 in the better eye with best correction or a visual field of less than 20 degrees. Legal blindness can mean tunnel vision, no central vision, cloudy or extremely blurred vision , seeing just shadows, or no vision at all. What does 20/200 mean? A person with normal visual acuity can see an object clearly, at 200 feet ; a legally blind person must be 20 feet or closer to see the same object. Many different types of visual impairments are caused by conditions such as diabetes, retinitis pigmentosa, cataracts, and macular degeneration. Blind people succeed in the workplace because of access technology, special fixtures and equipment that compensate for various types of visual loss. Low vision devices are also instrumental in maximizing residual vision, not only for work, but also for other aspects of life. Some low vision solutions involve only a hand-held magnifier, the introduction of increased lighting or an adjustment of the background against which a person is working. More complex solutions such as miniature telescope lenses mounted onto eyeglasses or devices to magnify text or the visual field are common.

A person who is deaf-blind has a unique experience of the world. For people who can see and hear, the world extends outward as far as his or her eyes and ears can reach. For the young child who is deaf-blind, the world is initially much narrower. If the child is profoundly deaf and totally blind, his or her experience of the world extends only as far as the fingertips can reach. Such children are effectively alone if no one is touching them. Their concepts of the world depend upon what or whom they have had the opportunity to physically contact. Who Is Deaf-Blind, and what are the Causes of Deaf-Blindness?

Home About Us Departments Send an e-Card ... Your Hospital Visit 171 Ashley Ave. Charleston, SC 29425 800-424-MUSC Print Version Medical Genetics X-linked Recessive: Red-Green Color Blindness, Hemophilia A Genes are inherited from our biological parents in specific ways. One of the basic patterns of inheritance of our genes is called X-linked inheritance. What is X-linked inheritance? X-linked inheritance means that the gene causing the trait or the disorder is located on the X chromosome. Remember, females have two X chromosomes, while males have one X and one Y. Genes on the X can be recessive or dominant, and their expression in females and males is not the same because the genes on the Y chromosome do not exactly pair up with the genes on the X. X-linked recessive genes are expressed in females only if there are two copies of the gene (one on each X chromosome). However, for males, there only needs to be one copy of an X-linked recessive gene in order for the trait or disorder to be expressed. For example, a woman can carry a recessive gene on one of the X chromosomes unknowingly, and pass it on to a son, who will express the trait: Therefore, half of the daughters have the gene and can pass it to the next generation. The other half do not have the gene and, therefore, cannot pass it on. Half of the sons do not have the gene and cannot pass it on. The other half of the sons have inherited the gene and will express the trait or disorder.

Back to Home About Me My Forums In the News ... Tell A Friend After your done reading this page take the colorblind "Selftest" Alot of people have no clue what it means to be colorblind. Here is some quickfacts: First of all most color impaired can see all colors. Very few color blind people can only see in black in white (less than 1% of us). Color blindness is the inability to perceive differences between some colors that other people can distinguish. It is most often of genetic nature, but might also occur because of eye, nerve or brain damage or due to use of some chemical substances. 5% to 8% of the men and 0.5% of the women of the world are born colorblind. A color-defective male always inherits his deficiency from his mother, the mother however is not colorblind The defect of color vision that is characterized by the inability to see the color red is called protanopia. Bulls are not colorblind, it is the motion of the cape which angers them. In World War II, colorblind men were sent on special missions, because their decreased ability to see green led to an increased ability to see through or detect camouflage. Famous People: Mr. Rogers
