Exempel på hur man kan använda SCOTOMA i en mening

• Blind spot (vision), also known as the physiological blind spot, the specific scotoma in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the optic disc.
• A scotoma is an area of partial alteration in the field of vision consisting of a partially diminished or entirely degenerated visual acuity that is surrounded by a field of normal – or relatively well-preserved – vision.
• In 1869, Jacob Hermann Knapp described scotoma and metamorphopsia in traumatic maculopathy with choroidal rupture using horizontal lines.
• For many sufferers, scintillating scotoma is first experienced as a prodrome to migraine, then without migraine later in life.
• The scintillating scotoma of migraine in humans may be related to the neurophysiologic phenomenon termed the spreading depression of Leão.
• During ASCs, which can be induced in a number of ways, the first stage of hallucination experienced by a subject contains only entoptic phenomena, such as the scintillating scotoma experienced by migraine sufferers.
• Some authors, such as Charles Singer, have suggested that the characteristics of the descriptions of the visions and the illustrations, such as bright lights and auras, imply they may have been caused by scintillating scotoma, a migraine condition.
• As a result of his campimetric tests he discovered a small glaucomatous scotoma that was to become known as a "Bjerrum scotoma", which is a visual field defect that goes by several other names, such as "sickle scotoma", "arcuate scotoma" or "scimitar scotoma".
• Papillitis can be differentiated from papilledema by an afferent pupillary defect (Marcus Gunn pupil), by its greater effect in decreasing visual acuity and color vision, and by the presence of a central scotoma.
• Preferential hyperacuity perimetry (PHP) is a psychophysical test used to identify and quantify visual abnormalities such as metamorphopsia and scotoma.
• Their stereoacuity is often in the range of 3000 to 70 arcseconds, and a small central suppression scotoma of 2 to 5 deg.
• Proves the presence or absence of normal (bifoveal) binocular single vision - thereby revealing if there is a central or paracentral suppression scotoma.
• Traquair described the scotoma which bears his name as follows:‘At the chiasmal termination of the nerve the crossed and uncrossed fibres separate, and a small lesion may occur at this point and effect the crossed fibres only, producing a unilateral temporal hemianopic or quadrantic central scotoma called ‘‘junction’’ scotoma, since it indicates the site of the lesion at the junction of the optic nerve and chiasma’.
• Anterior chiasmal syndrome, the lesions that affect the ipsilateral optic nerve fibres and the contralateral inferonasal fibres located in the Willebrand knee produce junctional scotoma, i.
• It can be used for rapid and gross assessment of large-scale visual field problems due to ophthalmological or neurological diseases, such as homonymous and heteronymous hemianopias, quadranopsia, altitudinal visual loss, central/centrocecal scotoma etc.
