Bitemporal hemianopia with or without central scotoma is present if the lesions have affected the body of the chiasm.
12.
Of a long list of possible symptoms, the most common presentations include : headaches, growth failure, and bitemporal hemianopsia.
13.
"' Bitemporal Modeling "'is an information modeling technique designed to handle historical data along two different timelines.
14.
The most common facial features of SLOS include microcephaly, bitemporal narrowing ( reduced distance between temples ), capillary hemangioma of the nose.
15.
Symptoms found include headaches ( bitemporal or occipital ), the inability to close the eyes or mouth, and may cause the reduction of taste.
16.
The anatomy of this structure causes pressure on it to produce a defect in the temporal visual field on both sides, a condition called bitemporal hemianopsia.
17.
Compression of the optic chiasm can lead to bitemporal hemianopsia, and, when there is no relevant trauma, this clinical finding is pathognomonic for a pituitary tumor.
18.
If originating superior to the optic chiasm, more commonly in a craniopharyngioma of the pituitary stalk, the visual field defect will first appear as bitemporal superior quadrantanopia.
19.
Common problems of the visual field include scotoma ( area of reduced vision ), hemianopia ( half of visual field lost ), homonymous hemianopsia and bitemporal hemianopia.
20.
Performing a physical examination to determine any visual field defect may be necessary if a pituitary lesion is suspected, which may compress the optic chiasm, causing typical bitemporal hemianopia.
