Extractions: Color blindness takes many forms. About one in ten boys and one in 250 girls are born with red-green color blindness, which is usually no more than an annoyance. But color blindness has much more seriousthough much rarerforms. The most severe is achromatopsia, a partial or complete lack or dysfunction of the cone cells. These are the color-sensing cells in the retina in the back of the eye. People with achromatopsia can see little or no color. They also never develop sharp vision; they are especially limited in their ability to see at a distance. Most are legally blind, with visual acuities around 20/200. This inherited disorder affects about 1 person in 33,000. Most patients are diagnosed as children. The main symptom of achromatopsia is extreme sensitivity to light (photophobia). Patients are blinded by the sun when they're outdoors. Some are so sensitive to light that they're uncomfortable even indoors in a normally lit room. The condition is hard to diagnose because the back of the eyes usually look normal when the doctor checks them. The diagnosis is made by the person's symptoms and an electroretinogram, which must be done at a special clinic. While there is no cure, the symptoms can be managed. Patients can control glare by wearing wraparound sunglasses and a broad-brimmed hat. An eye doctor can prescribe tinted contact lenses that cut glare and let patients see more clearly (the young boy in the TV spot got red lenses). Patients may also benefit from low vision rehabilitation, which may also include occupational therapy, orientation and mobility instruction (to learn safe walking and travel skills), social work, genetic counseling, and consultation with a teacher of the visually impaired.

Extractions: The Low Vision Centers of Indiana 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. Complete Achromatopsia Achromatopsia 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.

Extractions: based on Last Update 01 Nov 01 Rhodonine and Activa are trademarks There must be a distinct line between the medical and biological aspects of syndromes as serious as achromatopsia. This material should not be considered medical advice. Subjects aware of this syndrome should speak with their doctor. This webpage does not offer any alleviation of these symptoms in the near future. Because of the currency of some of the material presented below, students subject to rote testing based on the content of their textbooks are encouraged to review the Cautions Page before proceeding. Others may find the material controversial. However, the results speak for themselves. Achromatopsia (with an s) is a stationary congenital disease that is easily recognized in the clinic. It typically presents four different individual symptoms: However, the severity of these individual symptoms may vary from very severe (complete) cases to less severe (incomplete) cases. The incomplete cases can vary widely.

http://www.kufm.kagoshima-u.ac.jp/~rehabil/koza/jobs/achromatopsia.html

Extractions: These symptoms, combined with the CT and MRI findings, suggest that the (right) fusiform gyrus, as well as area V4 as noted in monkey studies, is important in the transaction or transmission of visual information about objects, faces, and colors. Additionally, the preservation of visuospatial cognition in the present case suggests that the projection to the parietal lobe from the occipital lobe for visuospatial cognition diverged before the fusiform gyrus. The recovery of color cognition is understandable in the present case given the large number of cells in this region which are sensitive to red color. Author's information (in Japanese) is here.

Congenital achromatopsia is not progressive, and it does not lead to blindness.What causes achromatopsia? What are the signs of achromatopsia?
http://www.visionrx.com/library/enc/enc_achromatopsia.asp

Extractions: Achromatopsia is a congenital eye defect that results in severe color blindness, poor detail vision, and photophobia, which is sensitivity to light. A hereditary condition, it occurs in 1 of 33,000 people in the United States, and it is more likely to occur in men than women. Congenital achromatopsia is not progressive, and it does not lead to blindness. The cells that make up the retina are responsible for the ability to see detail, brightness, and color. There are two types of photoreceptor cells in the cornea rods and cones. The rods specialize in work at low light levels, and the cones provide sharp vision, color, and contrast discrimination. People with achromatopsia have defective cone cells and must rely on their rod photoreceptors for vision. In normal eyes, there are about 6 million cone photoreceptors, located mainly in the macula at the center of the retina . These cells are primarily responsible for sharp, straight-ahead vision and also for the ability to distinguish colors. There are 100 million rod receptors, located mostly at the periphery of the retina. The rods are more sensitive to light than cones are, but rods are not able to differentiate among colors, nor can they perceive shades of gray, black, and white. (

Re RE achromatopsia and any drivers? Follow Ups Post Followup LowVision Driving In Reply to Re RE achromatopsia and any drivers?
http://www.biopticdriving.org/archive/webboard/driving/messages/1691.html

Extractions: Now to answer the question (which is based on information I gathered from the publication "Understanding and Coping with Achromatopsia"), there are very few persons diagnosed with achromatopsia who have sufficient vision to become drivers. The average visual acuity of persons with achromatopsia ranges from 20/160 to 20/200; there is a wide range of visual functioning among persons diagnosed with achromatopsia. In addition to the individual's range of acuity, much will also depend on the degree of photophobia (sensitivity to light) which can also greatly affect daytime acuity. For example, my 4-yr-old functions quite normally indoors and many people don't even realize he is visually impaired (indoors); but as soon as he is outdoors in daylight, even with dark sunglasses, it becomes quite apparent that he has greatly reduced acuity. I believe that those people with achromatopsia who do drive are likely "incomplete achromats" meaning that there is some degree of functioning cone photoreceptor cells in the retina. Traits to look for that "might" indicate a future in driving would include: a high degree of visual functioning, minimal photophobia, ability to easily use monocular aids, and a long-term demonstration in daytime orientation and mobility such as bike riding, skating, etc, especially.
