| Summary: |
Purpose: The aim of
the work was to catch the type of damage of optic nerve
in the group of patients with multiple sclerosis.
Material and methods: The examinations were held
on 77 eyes of 40 patients with multiple sclerosis. Among
them 11 patients had previous optic neuritis, 29 have
not problems with vision. The examination was conducted
by CSV-1000 contrast test depict on contrast sensitivity
function and anomaloscopy AN-69 appointing coefficient h
and threshold of red, green and blue hue.
Results: As a result, two groups of selective
damage and one of non-selective eyes were obtained. In 5
eyes (6,5% examined group eyes) were selective damage of
contrast sensitivity in 18 cdg connected with increased
threshold for blue hue. The second group of 4 eyes (5,2%
examined eyes) were characteristic by damage of contrast
sensitivity in 12 cdg and increased threshold of red hue
on the border of probable protanomaly. The rest 60 eyes
(77,9 % the examined group) were non-selective in
psychophysical tests. In the eyes of that group were
stated non-specific dyschromatopsy connected with equal
decrease of contrast sensitivity function, with the
tendency to serious changes in high spatial frequency.
Conclusions: Psychophysical tests enable early
diagnosis and monitoring of optic nerve damage in
multiple sclerosis patients. |
