| carotid artery bruit | <radiology> Differential diagnosis: Atherosclerotic plaque or stenosis in common carotid artery or major vessels., Normal vessel. Asymptomatic bruits are a risk factor for stroke, and 75% of strokes occur in the carotid circulation. The majority of patients with bruits will have stenosis of 50% or more. The vast majority (90%) of strokes occur without prior symptoms. REF: MacNeil BJ, Abrams HL. Brigham and Women's Hospital Handbook of Diagnostic Imaging. Chapter 27. (12 Dec 1998) |
| carotid bruit | <cardiology, clinical sign> A systolic murmur heard at the root of the neck (over a carotid artery) that is produced by turbulence from a blockage of blood flow in the vessel, can indicate carotid artery occlusive disease. See: stroke. (27 Sep 1997) |
| Roger's bruit | A loud pansystolic murmur maximal at the left sternal border, caused by a small ventricular septal defect. Synonym: bruit de Roger, Roger's bruit. (05 Mar 2000) |
| systolic bruit | Any abnormal sound or any murmur heard during systole. (05 Mar 2000) |
| thyroid bruit | Vascular murmur heard over hyperactive thyroid gland, due to increased blood flow. (05 Mar 2000) |
| Traube's bruit | A triple cadence to the heart sounds; due to an abnormal third or fourth heart sound being heard in addition to the first and second sounds, and usually indicative of serious disease. Synonym: bruit de galop, cantering rhythm, gallop rhythm, Traube's bruit. (05 Mar 2000) |
| accommodation, ocular | The dioptric adjustment of the eye (to attain maximal sharpness of retinal imagery for an object of regard) referring to the ability, to the mechanism, or to the process. It is the effecting of refractive changes by changes in the shape of the crystalline lens. Loosely, it refers to ocular adjustments for vision at various distances. (12 Dec 1998) |
| adaptation, ocular | The adjustment of the eye to variations in the intensity of light. Light adaptation is the adjustment of the eye when the light threshold is increased; dark adaptation when the light is greatly reduced. (12 Dec 1998) |
| albinism, ocular | Albinism affecting the eye in which pigment of the hair and skin is normal or only slightly diluted. The classic type is x-linked (nettleship-falls), but an autosomal recessive form also exists. Ocular abnormalities may include reduced pigmentation of the iris, nystagmus, photophobia, strabismus, and decreased visual acuity. (12 Dec 1998) |
| anterior ocular segment | That portion of the eye comprising the cornea, iris, lens, and their associated chambers and adnexa. (05 Mar 2000) |
| cardinal ocular movements | Eye rotations to the right and left, upward to the right and left, and downward to the right and left, to diagnose positions of gaze. (05 Mar 2000) |
