Extractions: This 160-page, spiral bound book, first published in 1998 and updated in 2003, presents a substantial amount of helpful and interesting information pertaining to achromatopsia. This is a very useful book not only for individuals and families who are affected by this rare vision disorder but also for vision care professionals, special education teachers, counselors, and other professionals who work with the visually impaired. The information that is included in this book was gathered in various ways, including input from members of the Achromatopsia Network, library research, and consultations with specialists in different fields. The author, Frances Futterman, has complete achromatopsia. She serves as facilitator of the network and also editor and reporter for the Achromatopsia Network Journal. Following are titles from the Table of Contents page of the current edition of Understanding and Coping with Achromatopsia: What is achromatopsia? What is it like to have achromatopsia?

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.

How Do People Inherit Colorblindness? How Often? People who are protans (red weak) and deutans (green weak) comprise 99% of this group.Molecular genetics. People with achromatopsia and blue cone monochromacy. http://webexhibits.org/causesofcolor/2C.html
Extractions: (no cones) Most kinds of congenital colorblindness are caused by defects in the X chromosome. Since females have two X chromosomes and males have an X chromosome and a Y chromosome, colorblindness is much more common in males: females must have defects in both chromosomes before they exhibit colorblindness. A female with the colorblindness defect in one X chromosome is a carrier of colorblindness. Male children of a female carrier are as likely to be colorblind as male children of a male with colorblindness, and male children of a male with colorblindness and a female carrier are extremely likely to be colorblind. Approximately 5% to 8% of the men and 0.5% of the women of the world are born colorblind. That's as high as one out of twelve men and one out of two hundred women. People who are protans (red weak) and deutans (green weak) comprise 99% of this group. Molecular genetics

Extractions: What Is Achromatopsia? Congenital achromatopsia is a rare hereditary vision disorder which affects 1 person in 33,000 in the U. S. The incidence varies in different parts of the world. Persons who have achromatopsia do not have normal "cone vision." In normal eyes there are 6 million cone photoreceptors, located mostly at the center of the retina. Persons with complete achromatopsia must rely on their "rod vision." In the normal eye there are 100 million rod photoreceptors. Rods are located mostly at the periphery of the retina. Rods "saturate" at higher levels of illumination. Rods do not provide color vision or good detail vision. Therefore, persons with achromatopsia are either totally colorblind or almost totally colorblind, and they have poor visual acuity. Without normal cone vision, their eyes are not able to adapt normally to higher levels of illumination.

Extractions: Availability This site: HTML PDF PS Abstract Achromatopsia, or total color blindness (also referred to as "rod monochromacy"), is a severe retinal disorder characterized clinically by an inability to distinguish colors, impaired visual acuity in daylight, photophobia, and nystagmus. Inherited as an autosomal recessive trait, achromatopsia is rare in the general population (1:20,000 1:50,000). Among the Pingelapese people of the Eastern Caroline Islands, however, the disorder occurs at an extremely high frequency, as recounted in Oliver Sacks's popular book The Island of the Colorblind 10% of this island population have the disorder and 30% carry the gene. This extraordinary enrichment of the disease allele most likely resulted from a sharp reduction in population in the late 18th century, in the aftermath of a typhoon and subsequent geographic and cultural isolation. To obtain insights into the genetic basis of achromatopsia, as well as into the genetic history of this region of Micronesia, a genomewide search for linkage was performed in three Pingelapese kindreds with achromatopsia. A two-step search was used with a DNA pooling strategy, followed by genotyping of individual family members. Genetic markers that displayed a shift toward homozygosity in the affected DNA pool were used to genotype individual members of the kindreds, and an achromatopsia locus was identified on 8q21

Extractions: When Irene Maumenee, M.D., the Ort Family Professor of Ophthalmology, founded the first Center for Hereditary Eye Diseases at Wilmer, she helped establish an area of ophthalmic research which today includes not only her classic studies of achromatopsia (lack of color vision) among Micronesian islanders and the discovery of the achromatopsia gene by Olof H. Sundin, Ph.D., but also groundbreaking work in the new fields of molecular genetics and biology, pursued in several laboratories throughout the Institute. The goal of the molecular researchers is to develop new tools to diagnose, prevent, and even cure major blinding diseases such as age-related macular degeneration and diabetic retinopathy For example, the laboratory of Peter A. Campochiaro, M.D., the George S. and Dolores Dora Eccles Professor of Ophthalmology, is investigating, among many other topics, the role of vascular endothelial growth factor in macular degeneration and diabetic retinopathy, and the possibility of stopping abnormal blood vessel growth using an oral medication. Dr. Campochiaro and Betsy Campochiaro, R.N., his wife, together with Donald Zack, M.D., Ph.D., have launched the Wilmer Genetic Study of Macular Degeneration, involving DNA analysis of thousands of people over several years. They have recently discovered genetic mutations involved in the disease.

Extractions: An International Referral Center for Genetic Eye Diseases and Ocular Diseases of Childhood Many eye diseases have a genetic component; similarly, many genetic diseases and birth defects have significant ocular pathology. Irene H. Maumenee, M.D The Laboratory of the Johns Hopkins Center for Hereditary Eye Diseases has developed a DNA registry and receives specimens from all over the world. Sophisticated tests performed in the laboratory include those for diseases such as oculocutaneous albinism, retinitis pigmentosa and other hereditary retinal dystrophies, retinoblastoma, colobomatous malformations, anterior segment malformations, storage diseases, familial retinal detachments (including Norrie disease), congenital cataracts, dislocated lenses, and congenital glaucoma. The Center's laboratory will soon offer clinical DNA diagnosis of some genetic eye diseases, including affection, carrier status and prenatal diagnosis. More than 55 fellows have been trained in the Johns Hopkins Center for Hereditary Eye Diseases; many have established similar centers in the USA and abroad.
