This eye condition is so rare, that information regarding it, can be hard to find. ANY information regarding driving and achromaptopsia would be GREATLY appreciated. Thank you.

Extractions: Achromatopsia Larger Ca permeability of mutant cone CNG channels causes incomplete achromatopsia Genetic analyzes identified mutations that have been associated with recessively inherited colorblindness, also known as achromatopsia . The vast majority of these mutations have been identified in the genes encoding CNGA3 and CNGB3, the two subunits of the cyclic nucleotide-gated (CNG) channel of cone photoreceptors (Figure 1). Figure 1: Transmembrane topology of a CNG channel subunit and the composition of the cone CNG channel. The cone CNG channel subunits CNGA3 (A) and CNGB3 (B) are assumed to adopt similar topologies with 6 transmembranal segments (S1-S6) and a pore forming region between S5 and S6. The amino (N) terminus and the carboxy (C) terminus, containing the cGMP-binding site, are located intracellularly. Recent evidence suggests that the cone CNG channel comprises three CNGA3 subunits and one CNGB3 subunit. CNG channels are located at high density in the plasma membrane of photoreceptors. These channels serve an important function in phototransduction (Figure 2): CNG channels are directly and cooperatively activated by cGMP. In the dark, the cGMP concentration in photoreceptors is high and open CNG channels conduct a depolarizing inward current carried by Ca

Extractions: home resource directory disorders quizzes ... support forums Advertisement ( (Redirected from Achromatopsia Maskun is a medical condition (also called achromatopsia ) characterized by a low cone 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. The condition is generally stable over the course of one's life. Many achromats function normally with the aid of darkened lenses, while others use guide dogs, canes, and are considered legally blind.

Color Vision Deficiency - Types - VisionChannel achromatopsia is the congenital, or inherited, inability to see color, A person with achromatopsia perceives the visual world in shades of gray, black, http://www.visionchannel.net/colorvision/types.shtml
Extractions: A dichromat has only two populations of cone cells. Typically, either the red or green population is absent in their retinas. There are three types of dichromacy: protanopia (red is absent), deuteranopia (green is absent), and tritanopia (blue is absent). In protanopia , also called "red weakness," the cone cells sensitive to red light are absent. A protanope is able to see blue, short wavelengths, but as light waves approach green in the spectrum, the perception becomes gray, and longer wavelengths, normally red, are seen as yellows. This type affects 1% of men and 0.02% of women. In deuteranopia the perception of color is very similar to what a protanope sees. In this type, also called "green weakness," cone cells sensitive to green light are absent. It affects 1% of men and 0.01% of women.
