Lice are tiny parasitic insects that feed on human blood. Three different species of these wingless insects infest the human head, body and pubic region. Lice cannot fly or hop. They spread from person to person through close contact. Lice...
The back of the eye is lined with a sensitive layer of tissue called the retina. One area of the retina, called the macula, controls central vision, used for reading, watching television and face recognition. Doctors diagnose a person with macular...
The macula is located on the retinal tissue that lines the back of the eye. A healthy macula helps provide the central vision you use each day for reading, watching TV and driving. Macular degeneration breaks down the cells in the macula,...
Age-related macular degeneration, or AMD, is the leading cause of blindness in Americans over age 65. As the baby-boomers age, a greater percentage of people will be affected by this disease. There are two main types of AMD, wet and dry....
Located in the foveal region of the retina, the macula is an important part of the visual system, responsible for clear central vision. A damaged macula means distorted vision when looking at objects straight ahead. Macular edema, one type of...
The macula is an area on the back of your eye that contains sensitive cells that help create the straight-ahead vision you use each day. Often with age, the cells of the macula break down, damaging vision. For most people, doctors cannot reverse...
As defined by the UK organization Retinal Surgery, vitreoretinal surgery is a surgical procedure for the treatment of problems of the eye involving the retina, macula, and vitreous humor. The retina is the part of the eye where light signals are...
When healthy, the middle of the retina, called the macula, provides clear images in the center of what the eyes see. With age-related macular degeneration, gradually accumulating damage to the macula causes a blind spot in the center of vision...
The macula, the central point of vision on the retina, normally attaches firmly to the back of the eye. Wrinkling of the retina that affects the macula, called a macular pucker, most often requires no treatment besides frequent eye exams to check...
The macula makes up a section of the back lining of the eye, and a healthy macula provides clear central vision. Macular degeneration occurs when the macula breaks down, damaging the central vision. Some people with macular degeneration experience...
Macular degeneration is an eye disease that affects vision. It occurs when the part of the eye called the macula, which is the central area of the retina, deteriorates. The macula is the area of the retina that allows the eye to see details, so...
The back, inner section of your eye has a lining called the retina, and the central portion of the retinal tissue is the macula. If the cells of the macula break down, this can result in a condition called macular degeneration. Knowing the...
The back of the eye has a light-sensitive lining called the retina, responsible for transforming light and images into signals for the brain. The macula sits in the central part of the retina, converting light and images in the central,...
Macular degeneration is an eye disease that results in permanent vision loss. Early symptoms may include blurry vision. You may find it more difficult to read, watch television or recognize the faces of friends and family. As the condition...
Macular degeneration, or MD, causes more blindness in American adults older than 60 than any other cause, the University of Maryland Medical Center reports. MD is caused by free radical damage in the macula -- the area of the retina responsible...
William A. Reeves, M.D., created TEBS Total Eye and Body Support multivitamin in 1996 after his research lead him to believe a specific formulation of vitamin and minerals could benefit the health of both the eyes and the body, according to the...
The retina lines the back of the eye and plays an important part in passing visual information to the brain. An area of the retina, called the macula, helps provide clear central vision, the vision used for reading and looking at faces. Wet...
The lining that covers the back of your eye contains an area of tissue called the macula. This area helps provide you with straight-ahead vision. Damage to this tissue may result in macular degeneration, an eye disease that can lead to vision...
Vision-threatening eye disorders commonly affect the elderly. One in every three people over age 65 has an eye condition that may cause vision loss, according to Dr. David A. Quillen of Pennsylvania State University College of Medicine. Being...
"Wet" macular degeneration progressively robs patients of their central vision. The Merck Manuals says 90 percent of all cases of blindness due to macular degeneration occur in the 10 percent of patients who have the wet form, which always occurs...
Macular degeneration is a very serious eye disease. It destroys the macula lutea, a small, thin area of the retina responsible for seeing clearly. Positively correlated with increased age is age-related macular degeneration, or AMD. Stargardt...
The retina lines the inner back portion of your eye, and in the central area of the retina sits the macula, a spot of tissue responsible for aiding in straight-ahead vision. Blood vessels feed the macula, and if these vessels leak, the macula may...
In the human eye, the macula is a part of the retina and is responsible for sharpening and refining visual images perceived by the eye. Macular degeneration, which is also called age-related macular degeneration, is an eye condition that occurs...
The back of your eye has a lining called the retina, and one area of the retina is the macula which provides the straight-ahead vision you use for tasks such as reading. Wet macular degeneration occurs when abnormal, fragile blood vessels grow and...
The retina is a thin layer of nerve tissue located at the back of the eye that is involved in interpreting the light that enters the eye. From there it converts the light into nerve signals, which travel up through the optic nerve to the brain....
The retina lines the inside of the eye, passing visual information to the optic nerve. An area of the retina, called the macula, is responsible for central vision. Two types of macular degeneration result from damage to the macula: Dry macular...
The macula is the part of the retina with photoreceptor cells called cones, enabling visual acuity. According to Mitchell Scheiman, Maxine Scheiman and Stephen G. Whittaker authors of “Low Vision Rehabilitation,” the condition called...
Macular degeneration occurs when the aging eye is unable to remove waste products efficiently and fat-like deposits called drusen form under the center of the retina, called the macula. Drusen are found in dry macular degeneration, the more...
Many older adults have a condition known as macular degeneration, which causes often causes permanent loss of vision. This condition typically affects your central vision--the vision you use for fine detailed work, as well as for watching TV and...
