Colour vision abnormalities in multiple sclerosis.
A battery of colour vision tests was employed to evaluate visual function in patients with multiple sclerosis (M.S.). Colour deficits were found in 45% of patients tested with the Ishihara plates and 42.5% of patients tested with the FM 100-Hue test. 65% of M.S. patients failed at least one of the tests. The colour vision deficits were not restricted to patients with optic neuritis or with visu...
متن کاملSpatiotemporal contrast sensitivity and colour vision in multiple sclerosis.
Measures of contrast sensitivity and colour vision were taken from a group of 18 multiple sclerosis patients. Contrast sensitivity losses, measured at 5 spatial frequencies and 4 temporal frequencies, were found to be significant in 11 patients. Red/green (Rayleigh equation) and green/blue (Engelking-Trendelenburg equation) Pickford-Nicolson anomaloscope settings were abnormal in 15 patients. C...
متن کامل7T MRI: New Vision of Microvascular Abnormalities in Multiple Sclerosis
Background—Although the role of vascular pathology in multiple sclerosis (MS) lesions was suggested long ago, the derivation of these lesions from the vasculature has been difficult to assess in vivo. Ultra-high-field (e.g. 7T) MRI has provided an imaging tool for assessing vascular involvement in MS lesions due to markedly increased image resolution and susceptibility contrast of venous blood....
متن کاملCongenital Abnormalities and Multiple Sclerosis
BACKGROUND There is a strong maternal parent-of-origin effect in determining susceptibility to multiple sclerosis (MS). One hypothesis is that an abnormal intrauterine milieu leading to impaired fetal development could plausibly also result in increased susceptibility to MS. A possible marker for this intrauterine insult is the presence of a non-fatal congenital anomaly. METHODS We investigat...
متن کاملColour vision impairment is associated with disease severity in multiple sclerosis.
BACKGROUND Colour vision assessment correlates with damage of the visual pathway and might be informative of overall brain damage in multiple sclerosis (MS). OBJECTIVE The objective of this paper is to investigate the association between impaired colour vision and disease severity. METHODS We performed neurological and ophthalmic examinations, as well as magnetic resonance imaging (MRI) and...
