Myopia
Myopia, commonly known as nearsightedness, is a common refractive error of the eye where distant objects appear blurry while close objects can be seen clearly. This condition occurs when the eyeball is too long or the cornea is too curved, causing light entering the eye to focus in front of the retina rather than directly on it.
Myeloma
Myeloma, also known as multiple myeloma, is a type of blood cancer that originates in the plasma cells of the bone marrow. Plasma cells are a type of white blood cell responsible for producing antibodies that help fight infection. In multiple myeloma, abnormal plasma cells (myeloma cells) multiply uncontrollably, crowding out healthy blood cells and producing abnormal proteins that can cause damage to various parts of the body, including bones, kidneys, and the immune system.
Myasthenia gravis
Myasthenia gravis (MG) is a chronic autoimmune neuromuscular disorder characterized by weakness and rapid fatigue of the voluntary muscles. It occurs when the immune system produces antibodies that interfere with the communication between nerves and muscles. The name "myasthenia gravis" comes from Latin and Greek origins, meaning "grave muscular weakness."
Muscular dystrophy
Muscular dystrophy (MD) refers to a group of inherited genetic disorders that cause progressive muscle weakness and degeneration. These disorders primarily affect skeletal muscles but can also impact other body systems. There are several types of muscular dystrophy, each with its own pattern of inheritance, age of onset, and specific muscle groups affected.
