    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. Incomplete Achromatopsia Patients 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.

    Extractions: 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.

    Extractions: based on Last Update 01 March 04 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 syndrome that is easily recognized in the clinic. It typically presents five different individual symptoms: Each of the above symptoms may appear independently and without association with Achromatopsia. In such case, they may be caused by other underlying disease. Abnormal iris operation is common but frequently undocumented.

    Extractions: This condition affects approximately one in 40,000 live births. Its prevalence varies in different parts of the world. Because there is a genetic link, it is more common in regions where there is a high rate of consanguineous marriages (marriages between first cousins) and in the eastern pacific islands of Pingelap (see the book, ‘The Island of the Colourblind’ by Dr Sacks). Achromatopsia is caused by an abnormality of the retina, that portion of the eye responsible for “making the picture”. It is analogous to the film in a camera. In the retina, there are three types of cells (cones) that are responsible for normal color vision. These are the red cones, the green cones, and the blue cones. A balanced distribution of these cells is necessary for normal color vision. If a child is born with an absence of these cells, they will have achromatopsia. Sometimes children have a reduced compliment of the cones, in which case they will have partial or incomplete achromatopsia. Achromatopsia is an inherited condition and so far three genes (genetic markers found on chromosomes) are known to be associated with this condition: CNGA3, CGNB3 and GNAT2. The three chromosomes that may have changes associated with achromatopsia are chromosome 14, chromosome 8q21- q22 and chromosome 2q11.

    Extractions: Over US$225,000 has been donated since the drive began on 19 August. Thank you for your generosity! Achromatopsia is a medical condition (also called maskun or rod monochromatism ) characterized by a low cone cell count or lack of function in cone cells; these are the light receptors responsible for colour perception. It is endemic on Pohnpei and was described by Oliver Sacks in Island of the Colourblind . Sacks went there with a Norwegian who had maskun, and the book narrates his experiences on the island. People with maskun have difficulty seeing in bright daylight because their rod cells (the receptors responsible for detecting brightness) are saturated. People with normal colour vision do not perceive things in the same way as those with maskun, because they depend on colour more than on luminosity to identify objects and patterns, whereas achromatopics depend almost entirely on luminosity to identify patterns. The closest that normal-sighted persons can come to experiencing maskun-type vision is in the dark, when the rod cells become the predominant receptors for vision due to their sensitivity to variations in brightness. Achromatopsia can vary in its severity from being mild enough that it is not diagnosed to causing near blindness. It is a relatively rare condition requiring two recessive genes . In the United States, it affects approximately 1 in 33,000 people. The condition is generally stable over the course of one's life. Many
