Möbius Sign

	Möbius Sign Möbius sign is a clinical sign in which there is an inability to maintain convergence of the eyes. It is found in patients with Graves' disease. The sign is named after Paul Julius Möbius Paul Julius Möbius (January 24, 1853 – January 8, 1907) was a German neurologist born in Leipzig. His grandfather was German mathematician and theoretical astronomer, August Ferdinand Möbius (1790–1868). Prior to entering the medical field ....

picture info	Medical Sign Signs and symptoms are the observed or detectable signs, and experienced symptoms of an illness, injury, or condition. A sign for example may be a higher or lower temperature than normal, raised or lowered blood pressure or an abnormality showing on a medical scan. A symptom is something out of the ordinary that is experienced by an individual such as feeling feverish, a headache or other pain or pains in the body. Signs and symptoms Signs A medical sign is an objective observable indication of a disease, injury, or abnormal physiological state that may be detected during a physical examination, examining the patient history, or diagnostic procedure. These signs are visible or otherwise detectable such as a rash or bruise. Medical signs, along with symptoms, assist in formulating diagnostic hypothesis. Examples of signs include elevated blood pressure, nail clubbing of the fingernails or toenails, staggering gait, and arcus senilis and arcus juvenilis of the eyes. Indicati ...

picture info	Vergence A vergence is the simultaneous movement of both eyes in opposite directions to obtain or maintain single binocular vision. When a creature with binocular vision looks at an object, the eyes must rotate around a vertical axis so that the projection of the image is in the centre of the retina in both eyes. To look at an object closer by, the eyes rotate towards each other (convergence), while for an object farther away they rotate away from each other (divergence). Exaggerated convergence is called ''cross eyed viewing'' (focusing on the nose for example). When looking into the distance, the eyes diverge until parallel, effectively fixating the same point at infinity (or very far away). Vergence movements are closely connected to accommodation of the eye. Under normal visual conditions, looking at an object at a different distance will automatically cause changes in both vergence and accommodation, sometimes known as the '' accommodation-convergence reflex''. When under non-typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Human Eye The human eye is a sensory organ, part of the sensory nervous system, that reacts to visible light and allows humans to use visual information for various purposes including seeing things, keeping balance, and maintaining circadian rhythm. The eye can be considered as a living optical device. It is approximately spherical in shape, with its outer layers, such as the outermost, white part of the eye (the sclera) and one of its inner layers (the pigmented choroid) keeping the eye essentially light tight except on the eye's optic axis. In order, along the optic axis, the optical components consist of a first lens (the cornea—the clear part of the eye) that accomplishes most of the focussing of light from the outside world; then an aperture (the pupil) in a diaphragm (the iris—the coloured part of the eye) that controls the amount of light entering the interior of the eye; then another lens (the crystalline lens) that accomplishes the remaining focussing of light into ...

picture info	Graves' Disease Graves' disease (german: Morbus Basedow), also known as toxic diffuse goiter, is an autoimmune disease that affects the thyroid. It frequently results in and is the most common cause of hyperthyroidism. It also often results in an enlarged thyroid. Signs and symptoms of hyperthyroidism may include irritability, muscle weakness, sleeping problems, a fast heartbeat, poor tolerance of heat, diarrhea and unintentional weight loss. Other symptoms may include thickening of the skin on the shins, known as pretibial myxedema, and eye bulging, a condition caused by Graves' ophthalmopathy. About 25 to 30% of people with the condition develop eye problems. The exact cause of the disease is unclear; however, it is believed to involve a combination of genetic and environmental factors. A person is more likely to be affected if they have a family member with the disease. If one twin is affected, a 30% chance exists that the other twin will also have the disease. The onset of disease may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Paul Julius Möbius Paul Julius Möbius (January 24, 1853 – January 8, 1907) was a German neurologist born in Leipzig. His grandfather was German mathematician and theoretical astronomer, August Ferdinand Möbius (1790–1868). Prior to entering the medical field in 1873, he studied philosophy and theology at the Universities of Leipzig, Jena and Marburg. After earning his medical doctorate in 1876, he enlisted in the army, attaining the rank of ''Oberstabsarzt'' (senior staff surgeon). After leaving the army, he returned to Leipzig, where he opened a private practice and worked as an assistant to neurologist Adolph Strümpell (1853-1925) at the university policlinic. In 1883 he obtained his habilitation for neurology. He was a prolific writer and is well known for publications in the fields of neurophysiology and endocrinology. Among his writings in psychiatry were psychopathological studies of Goethe, Rousseau, Schopenhauer and Nietzsche. He was also an editor of ''Schmidt's Jahrbücher der in- ...
