A disease of the retina of the eye resulting in loss of central vision
One of the most common causes of decreased vision after age 60 Usually evident as a loss of pigment from pigment epithelium and deposits of yellowish material in the sub-pigment epithelial layer in the central retinal zone
= the leading cause of blindness for people over the age of 50; and eye disease that results from damage to the macula
When macular degeneration is complicated by abnormal blood vessel growth (the wet form), lasers can destroy the vessel and reduce the chance of further visual loss
A hereditary condition in which the cones in the central part of the retina degenerate
Degeneration of the photoreceptors in the macula or central region of the retina This area of the retina is responsible for central vision, used for reading, seeing faces, and so on Often associated with aging See Age-related Macular Degeneration in Eye Care Encyclopedia
an age-related deterioration of the central retina (macula) Macular degeneration can occur in either a dry form or wet form
-the macula is the small area in the retina of the eye, 3 to 5 millimeters in size, that provides the sharpest and clearest vision The macula can degenerate with the aging process, perhaps due to oxidation The fatty acid DHA is present in large amounts in the retina
degeneration of the cells of the macula lutea which results in blurred vision and can cause blindness; usually age-related
Eye's disease caused by abnormal growth of blood vessels in macula area The new blood vessels are very fragile, start to bulge, leak blood & fluid, lifting the retina off its membrane & ultimately leading to blindness
loss of vision due to wear and tear or damage to the macula There are two types: dry-type and wet-type, so called as the latter is caused by fluid flooding Occasionally, dry-type degeneration can lead to wet-type
Macular degeneration (AMD) is the result of degeneration of the macula, the central part of the retina that is responsible for seeing detail clearly It is the leading cause of vision loss in people over 50, and affects one-quarter of the aging population It's estimated that 13 million people in the U S and as many as 40 million people worldwide have signs of macular degeneration Every year, over 400,000 Americans are diagnosed with a severe form of macular degeneration, leading to functional blindness
A deterioration of the central part of the retina, which causes difficulty in seeing details clearly
The macula is the central part of the retina that enables you to read and see straight ahead (central vision) The cause is unknown Although macular degeneration can occur in children and young adults, it is more common in older person Fortunately, in macular degeneration, peripheral vision is not affected, and thus a person with macular degeneration does not face total blindness If you have macular degeneration you are usually able to move about unaided, but may find reading, close work, or distinguishing distant objects difficult or even impossible (Palin 7)
Macular degeneration is an eye disease that occurs when there are changes to the macula The Macula is a small portion of the retina that is located on the inside back layer of the eye It reduces central vision and makes seeing details for close work, like reading or sewing, difficult or impossible Macular degeneration is the leading cause of vision loss among people over the age of 50
Any deterioration of the macula tissue Most commonly used to describe Age Related Macular Degeneration, a condition characterized by pigment and blood vessel deterioration beneath the neurosensory macula
A broad term describing several diseases that lead to a loss of central vision See the Macular Degeneration FAQ
— (AOA) - Leading cause of blindness in America (JP) Common cause of decreased vision in adults over 60, evident as loss of pigment from pigment epithelium and deposits of yellowish matter in sub-pigment epithelial layer in central retinal zone (NERF) - The degeneration of the nerve endings in the macula area, which includes the fovea Senile macular degeneration refers to age related degeneration of this area Sometimes referred to as "ARMD", for age-related macular degeneration
A condition in which the cells of the macula lutea degenerate, resulting in blurred vision and ultimately blindness. Degeneration of the macula (central part of the retina), with corresponding visual-field defect. It is the leading cause of blindness in old age. Probably due to reduced blood circulation, it is now known to have a genetic component. It is twice as common in smokers as in nonsmokers, and it is also correlated with lifelong sun exposure. Peripheral vision usually remains, but loss of central visual acuity makes reading or fine work difficult or impossible, even with special magnifying eyeglasses. Some forms of macular degeneration can be halted (but not reversed) by laser surgery
­ Damage or breakdown of the macula, which is an area in the back of the eye that controls central vision The condition may be caused by injury or aging, and while it does not progress to total blindness, patients with macular degeneration may require special optical aides to enlarge distant and near objects
degeneration in the macular region of the retina that results in decreased central vision and sometimes, in blindness
is varying degrees of blurred vision resulting from damage to the retina The retina is the thin layer of tissue at the back of the eye that serves as a projection screen to send images to the brain The small central part of the retina responsible for the most detailed vision required for activities like reading, writing, and driving is the macula Age related macular degeneration (AMD) is the most common cause of blindness in people aged 65 and over Wet macular degeneration occurs when capillaries multiply abnormally under the retinal covering causing it to detach They also may bleed which can cause scar tissue to form This is the more common of the two types of macular degeneration
Loss of central vision as a result of changes, often related to aging, in the macula (the portion of the retina responsible for sharp, clear vision)
Another common type of retina degeneration which results in the loss of central vision but usually retains peripheral vision
A pigmentary disturbance in the macula lutea lying slightly lateral to the center of the retina in the eye, which brings the loss of central visual acuity
An abnormality of the blood supply to the light-sensitive portion of the retina that is primarily a result of aging
