Occipital proton magnetic resonance spectroscopy (1H-MRS) reveals normal metabolite concentrations in retinal visual field defects. [PDF]

open access: yesPLoS ONE, 2007
BACKGROUND: Progressive visual field defects, such as age-related macular degeneration and glaucoma, prevent normal stimulation of visual cortex. We investigated whether in the case of visual field defects, concentrations of metabolites such as N ...

Case Series Study of Visual Field Defects in Pituitary Gland Tumors [PDF]

open access: yesAl Ameen Journal of Medical Sciences, 2017
Background: The pituitary gland is a small endocrine gland, weighing about 500 mg. Pituitary adenomas account for 12-15 % of all intracranial tumors. Pituitary gland is in the sella turcica, 8-13 mm lower than the optic chiasm.
