Health Center Dictionary Encyclopedia Innovation Spotlight ... Eye Care Library Encyclopedia - Achromatopsia What causes achromatopsia? What are the signs of achromatopsia? How is achromatopsia managed? 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. What causes achromatopsia? 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. (

(GAPS) HOME DISORDERS GLOSSARY Acromatopsia also known as: Congenital Achromatopsia (as defined at http://www.achromat.org/what_is_achromatopsia.html 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.

The Macula Anatomy, Physiology and Pathology of the Human Eye Ted M. Montgomery, Optometric Physician Click on a selection here fovea centralis color vision color deficiency color vision testing macular degeneration Amsler grid cystoid macular edema central serous retinopathy , or scroll down the page. Full Page View The macula lutea is the small, yellowish central portion of the retina , and it is the area providing the clearest, most distinct vision. When one looks directly at something, the light from that object forms an image on one’s macula. A healthy macula ordinarily is capable of achieving at least 20/20 (“normal”) vision or visual acuity, even if this is with a correction in glasses or contact lenses. Not uncommonly, an eye’s best visual acuity is 20/15; in this case, that eye can perceive the same detail at 20 feet that a 20/20 eye must move up to 15 feet to see as distinctly. Some people are even capable of 20/10 vision, which is twice as good as 20/20. Vision this acute may be due to there being more cones per square millimeter of the macula than in the average eye, enabling that eye to distinguish much greater detail. fovea centralis The very center of the macula is called the fovea centralis , an area where all of the photoreceptors are cones ; there are no rods in the fovea. The fovea is the point of sharpest, most acute visual acuity. (The center of the fovea is the “foveola.”) Because the fovea has no rods, small dim objects in the dark cannot be seen if one looks directly at them. For this reason, to detect faint stars in the sky, one must look just to the side of them so that their light falls on a retinal area, containing numerous rods, outside of the macular zone.
