It ends in front of the sacroiliac joint, bifurcate the external iliac artery and internal iliac artery.LogMAR chart: A LogMAR chart comprises rows of letters and is used by ophthalmologists and vision scientists to estimate visual acuity. This chart was developed at the National Vision Research Institute of Australia in 1976, and is designed to enable a more accurate estimate of acuity as compared to other charts (e.Endoscopic vessel harvestingOptic disc: The optic disc or optic nerve head is the point of exit for ganglion cell axons leaving the eye. BecauseGuiding Eyes for the Blind: Yorktown Heights, New YorkPhonomyography: Phonomyography (PMG) (also known as acoustic myography, sound myography, vibromyography, and surface mechanomyogram)"It is important to underline here that the term "surface mechanomyogram" was suggested during a CIBA Foundation Symposium in 1995 to overcome the terminological confusion caused by the habit of identifying the phenomenon with the electrical signal produced by different transducers (microphones, accelerometers, piezoelectric transducers, LVDs, etc.) instead of with its mechanical origin" is a technique to measure the force of muscle contraction by recording the low frequency sounds created during muscular activity.Right-sided aortic arch: Right-sided aortic arch is a rare anatomical variant in which the aortic arch is on the right side rather than on the left. During normal embryonic development, the aortic arch is formed by the left fourth aortic arch and the left dorsal aorta.Vasodilation: Vasodilation (or vasodilatation) refers to the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins, large arteries, and smaller arterioles.ParacentesisNeuro-ophthalmology: Neuro-ophthalmology is an academically-oriented subspecialty that merges the fields of neurology and ophthalmology, often dealing with complex systemic diseases that have manifestations in the visual system. Neuro-ophthalmologists initially complete a residency in either neurology or ophthalmology, then do a fellowship in the complementary field.Aortic pressure: Central aortic blood pressure (CAP or CASP) is the blood pressure at the root of aorta. Studies have shown the importance of central aortic pressure and its implications in assessing the efficacy of antihypertensive treatment with respect to cardiovascular risk factors.Optic neuropathyRetinal regeneration: Retinal regeneration deals with restoring retinal function to vertebrates so impaired.Left gastric artery: In human anatomy, the left gastric artery arises from the celiac artery and runs along the superior portion of the lesser curvature of the stomach. Branches also supply the lower esophagus.Endothelial dysfunction: In vascular diseases, endothelial dysfunction is a systemic pathological state of the endothelium (the inner lining of blood vessels) and can be broadly defined as an imbalance between vasodilating and vasoconstricting substances produced by (or acting on) the endothelium. Normal functions of endothelial cells include mediation of coagulation, platelet adhesion, immune function and control of volume and electrolyte content of the intravascular and extravascular spaces.MethyldopaEisenmenger: Eisenmenger (German for "ironmonger") is a German surname. Notable people with the surname include:Common carotid artery: In anatomy, the left and right common carotid arteries (OED 2nd edition, 1989.Entry "carotid" in Merriam-Webster Online Dictionary.Vascular smooth muscleAnterior interventricular branch of left coronary artery: The left anterior descending artery (also LAD, anterior interventricular branch of the left coronary artery, or anterior descending branch), also known as the "widow maker", is an artery of the heart.Arterial embolismMedian arcuate ligament syndromeEndothelial activation: Endothelial activation is a proinflammatory and procoagulant state of the endothelial cells lining the lumen of blood vessels. It is most characterized by an increase in interactions with white blood cells (leukocytes), and it is associated with the early states of atherosclerosis and sepsis, among others.Carotid artery stenosisScanning laser ophthalmoscopySkip lesion: A skip lesion is a wound or inflammation that is clearly patchy, "skipping" areas that thereby are unharmed. It is a typical form of intestinal damage in Crohn's disease, but may also be the kind of damage to the renal tubules in acute tubular necrosis.Charles D. Phelps: Charles Dexter Phelps (September 16, 1937 – September 13, 1985) was a prominent American medical doctor, professor, and researcher in the field of ophthalmology. The clinical studies he oversaw contributed to significant advances in the scientific understanding and surgical and pharmacological treatment of glaucoma.Bronchial artery: In human anatomy, the bronchial arteries supply the lungs with nutrition and oxygenated blood. Although there is much variation, there are usually two bronchial arteries that run to the left lung, and one to the right lung.Antithrombotic: An antithrombotic agent is a drug that reduces the formation of blood clots (thrombi).http://cancerweb.Popliteal artery entrapment syndrome: The popliteal artery entrapment syndrome is a rather uncommon pathology, which results into claudication and chronic leg ischemia. The popliteal artery may be compressed behind the knee, due to congenital deformity of the muscles or tendon insertions of the popliteal fossa.Dorsal carpal branch of the ulnar artery: The dorsal carpal branch of the ulnar artery arises from the ulnar artery immediately above the pisiform bone, and winds backward beneath the tendon of the flexor carpi ulnaris; it passes across the dorsal surface of the carpus beneath the extensor tendons, to anastomose with a corresponding branch of the radial artery.Operation Eyesight Universal: Operation Eyesight Universal is a Canada-based international development organisation, founded in 1963. It works to prevent avoidable blindness and to cure blindness that is treatable.Optic nerve tumor: An optic nerve melanocytoma is a tumor made up of melanocytes and melanin. These tumors are typically a benign; they can grow, but rarely transform into a malignancy.
