Visual Conditions Shore Family Eyecare Treats Achromatopsia Achromatopsia is the abnormality or absence of retinal cones. There is a complete and incomplete form. Achromatopsia is a rare hereditary vision disorder which affects 1 person in 33,000 in the U.S. Someone with achromatopsia has little or no cone cell function in the retinas of their eyes. Cone cells permit color vision, perception of fine detail, and the ability to adapt to all higher levels of illumination. Cones provide "day vision." Signs and symptoms: Vision is worse in bright light. Eye function is markedly better in reduced illumination. Characteristics: visual acuity about 20/200 in complete form. Basically normal retina, or definite macular abnormality. Nystagmus is present. Total lack of color discrimination is pathognomonic. The cone ERG is absent as is the first portion of the scotopic red response in both the complete and incomplete forms. In children wiht poor acuity, nystagmus,, and a normal fundus, who are too young to treat, the ERG assumes a major role in differential diagnosis. In the incomplete forms of congenital cone blindness, the acuity range is better (20/40 to 20/100); there may be misleading and may be diagnosed as macular degeneration or ocular albinism. In these cases, the ERG is essential for confirming the diagnosis. Field: Normal Prognosis: nonprogressive. Vision remains relatively good in subdued light. Nystagmus and photophobia improves with age.

Products MSDS Store BioBeat Subscribe Contact Breakthroughs ... Awards Linkage Reported for Total Color Blindness in the Pingelapese by Michael D. O'Neill Significant evidence of genetic linkage has been reported between total color blindness ( achromatopsia ) and a region of chromosome 8 in the Pingelapese people of the South Pacific. This result was described by researchers from Rockefeller University who conducted a genome-wide linkage study for 61 individuals in three Pingelapese families. The clinical symptoms of achromatopsia include the complete inability to distinguish colors, impaired visual acuity in daylight, photophobia, nystagmus (jerking movements of the eye), and gradually developing cataracts. Affected individuals squint and have severe difficulty seeing in daylight. Their visual acuity is generally 1/10 or less that of normal individuals. The disease is associated with the absence or malfunction of the retinal cones, the special sensory cells responsible for normal trichromatic color vision. The cones are located in the fovea, the central region of the retina, and are specialized for sensing fine detail as well as color. Without functioning cones, individuals with achromatopsia also have difficulty holding their gaze steady (fixating), particularly in bright light, and their eyes make searching, jerky movements (nystagmus). Achromatopsia is inherited in an autosomal recessive fashion and is generally very rare, affecting an average of between 1 in 20,000 to 1 in 50,000 people around the world. In the Pingelapese, however, a population of roughly 1,000 individuals inhabiting the tiny atoll of Pingelap in the Eastern Caroline Islands (

Achromatopsia by Josh Kaitz and Stephen Rakusin Achromatopsia, a rare hereditary disorder, occurs in about one out of every thirty-three thousand Americans. In fact, some optometrists and Ophthalmologists can work a lifetime without diagnosing or even examining someone with Achromatopsia. This genetic disease causes complete color blindness due to irregular cone vision. Achromats must rely on their rod vision, which is not as powerful as cone vision, and thus they typically have poor visual acuity, hypersensitivity to light, and nystagmus. The gene is inherited as an autosomal recessive gene and is found on the second chromosome. The disease comes in many different severities from mild to severe: complete Achromatopsia, incomplete Achromatopsia, and blue cone Achromatopsia. This is an extremely hard disorder to diagnose because it is similar to cone dystrophy except achromat’s eyes do not continually worsen. The Achromatopsia gene is found on chromosome two at location 2q11( http://www.ajo.com after brought to this site, type in Achromatopsia at the search engine) , and it is inherited as a recessive gene. This means that it does not show up if a person has a dominant normal gene, but can show up in one’s children if each parent has this recessive gene. The name for the actual gene is CNGA3.

71. VISION IN A COMPLETE ACHROMAT is my hope, though, that my account will give both vision scientists and the generalreader a glimpse, not only into the manifestations of achromatopsia and rod http://www.u.arizona.edu/~chalmers/misc/achromat.html

VISION IN A COMPLETE ACHROMAT: A PERSONAL ACCOUNT By: Knut Nordby INTRODUCTION Being myself a vision scientist who is also a complete achromat, I have, upon demand from friends and collaborators, taken on the task of trying to convey some of my visual experiences and to explain how I cope with my visual handicap. I rely on recollections, both my own and those of my family, and try to separate information that can be documented or is supported by other sources from the mere anecdotal. I also draw on information from interviews with other achromats, but only to supplement or comment on my personal experiences. My recollections may have become distorted over time, they may not be precise and may also be biased - and they may not, in all cases, apply to other achromats. It is my hope, though, that my account will give both vision scientists and the general reader a glimpse, not only into the manifestations of achromatopsia and rod-vision - topics usually not covered by the learned papers - but also into the practical problems and obstacles encountered by a completely colour-blind person.

redrum, kidnapped, achromatopsia, molasses, neurological by Rachel JC managed to unlock the door, his vision starting to fade as he struggled to stay awake. He was so happy to be home finally and so unhappy at the same time. He didn't want to see what kind of condition Joey was in. The apartment was pitch black, but he could hear the TV on in the back room. He felt along the wall until he found the light switch, flooding the room in brightness. His jaw dropped and his bag slipped to the floor. The apartment was trashed. The bookshelf was pushed over, the kitchen was trashed. The chairs were thrown around. JC closed his eyes, pinching the bridge of his nose and trying to breathe slowly. This wasn't happening again. Joey was okay. When he opened his eyes, the apartment was going to be neat and tidy. JC opened one eye and sighed. This really was happening. He'd been awake for almost 52 hours now. He was not in the right frame of mind to deal with Joey at the moment. JC picked his way through the living room, careful not to step on anything. He headed for the back room where the TV was. The lights were off in there as well, but the TV was on. JC flipped the lights on and walked over to the couch, shaking Joey angrily. He didn't budge, just lying there like a limp rag as JC shook him. "Fuck." JC muttered. He picked up the remote and turned off the TV, cutting off the freaky kid from 'The Shining' while he was intoning the words 'redrum' yet again.

color blindness Alternative Names dyschromatopsia, achromatopsia, color vision deficiency Definition Color blindness ranges from the inability to distinguish similar shades of a color, to the complete inability to see color. Dyschromatopsia refers to the ability to see some colors, but not others. Achromatopsia, which is rare, refers to the inability to see colors at all. What is going on in the body? Most of the time, color blindness is a genetic defect that is present when the individual is born. Less commonly, color blindness occurs as part of aging or is caused by a medication or disease. What are the signs and symptoms of the condition? An individual with achromatopsia cannot tell the difference between colors. Some people with achromatopsia can only see shades of gray. A person with this condition usually has poor distance vision, light sensitivity, and rapid eye movement. Dyschromatopsia is the more common form of color blindness. Individuals with this condition usually have excellent vision. The person usually cannot tell the difference between shades of red and green. In rare cases, the person cannot tell the difference between shades of blue and yellow. What are the causes and risks of the condition?
