    Macrophage inhibitory cytokine 1: See: MIC-1....
  2. Macrophagic myofasciitis Macrophagic myofasciitis
    Macrophagic myofasciitis: A muscle disease first identified in 1993, macrophagic myofasciitis is named for the findings seen in tissue from muscle biopsies, namely an abnormal infiltrate surrounding muscle tissue of specialized immune cells called "macrophages," a type of immune cell important t...
  3. Macroscopic Macroscopic
    Macroscopic: Large enough to be seen with the naked eye, as opposed to microscopic. For example, a macroscopic tumor is big enough to be seen without the aid of a microscope. From the Greek macro- (large, long) + -scopic, from skopos (aim, mark)....
  4. Macrosomia Macrosomia
    Macrosomia: Overly large body. A child with macrosomia has significant overgrowth....
  5. Macrovascular Macrovascular
    Macrovascular: Pertaining to the macrovasculature, the portion of the vasculature of the body comprising the larger vessels, those with an internal diameter of more than 100 microns. By contrast to microvascular. The term macrovascular is somewhat less used than microvascular. There is a field of mi...
  6. Macrovascular disease Macrovascular disease
    Macrovascular disease: Disease of the large blood vessels, including the coronary arteries, the aorta, and the sizable arteries in the brain and in the limbs. Macrovascular disease is by contrast to microvascular disease. In persons with diabetes, chronic hyperglycemia (assessed by glycosylated hemo...
  7. Macula Macula
    Macula: A macula is a small spot. A macula on the skin is a small flat spot while the macula in the eye is a small spot where vision is keenest in the retina. The macula of the retina, the light-sensitive layer of tissue at the back of the eye, is the best known macula. It is in the center of the r...
  8. Macular Macular
    Macular: Pertaining to the macula. A macula is a small spot. A macula on the skin is a small flat spot while the macula in the eye is a small spot where vision is keenest in the retina. The macula of the retina, the light-sensitive layer of tissue at the back of the eye, is the best known macula....
  9. Macular (skin) Macular (skin)
    Macular (skin): Adjective referring to macules which are circumscribed changes in the color of skin that are neither raised (elevated) nor depressed. Macules are never large. They are little spots or blemishes in the skin. They are entirely flat and can only be appreciated by visual inspection; they...
  10. Macular cyst Macular cyst
    Macular cyst: A hole in the macula, the tiny oval area made up of millions of nerve cells located at the center of the retina responsible for sharp, central vision. The eye contains a jelly-like substance called the vitreous. Shrinking of the vitreous usually causes the hole. As a person ages, the ...
  11. Macular degeneration Macular degeneration
    Macular degeneration: A disease that progressively destroys the macula, the central portion of the retina, impairing central vision. Macular degeneration rarely causes blindness because only the center of vision is affected. However, injury to the macula in the center of the retina can impair the a...
  12. Macular hole Macular hole
    Macular hole: A hole in the macula, the tiny oval area made up of millions of nerve cells located at the center of the retina responsible for sharp, central vision. The eye contains a jelly-like substance called the vitreous. Shrinking of the vitreous usually causes the hole. As a person ages, the ...
  13. Macular pucker Macular pucker
    Macular pucker: Scar tissue in the macula, the area of the retina responsible for sharp central vision. The scar can blur and distort vision and make straight lines appear wavy. Macular pucker is due most often to age-related shrinkage of the vitreous which pulls away from the retina, causing the re...
  14. Macular retinopathy Macular retinopathy
    Macular retinopathy: Any pathologic condition or disease of the macula, the small spot in the retina where vision is keenest. Also called maculopathy....
  15. Macular vision Macular vision
    Macular vision: The macula is a special area in the center of the retina, the light-sensitive layer of tissue at the back of the eye. As we read, light is focused onto our macula. There, millions of cells change the light into nerve signals that tell the brain what we are seeing. This is called our ...
