[The usefulness of visual evoked potentials for the evaluation of visual pathways in children and adolescents with selected neuro-ophthalmological syndromes. (Summary of the doctor of medicine degree dissertation)].
OBJECTIVE
Much study and care have been devoted to evaluated lesions of the visual pathway in children and adolescents with different neuroophthalmological disorders. The aim of the study was to determine the usefulness of visual evoked potentials (VEP) for evaluation of visual pathway in young patients with cerebral palsy, sclerosis multiplex and subacute sclerosing panencephalitis.


METHODS
During the research 63 healthy children and 78 pathological ones, between 5 and 18 years of age, were studied. First ophthalmological examination was performed and next VEPs were recorded. For poorly cooperative children, a flash on TV screen was used as a stimulus, and for normal mental children a pattern-reversal black and white checkboard was used. The comparison of VEP in normal healthy subjects and pathological ones was the last part of the investigation to evaluate visual system of patients.


RESULTS
In all groups of patients, both with visual complains and without them, pathological results of VEP were found. The pathology of VEP were connected with shape, amplitudes and latencies of the peaks N75, P100, N145.


CONCLUSIONS
The VEP is a good and objective method of diagnosis in neuroophthalmological patients, which supplies extra information about lesions of visual pathway. It allows to detect subclinical lesions. It is a noninvasive and painless diagnostical method and it can be repeated a few times in various periods of illness and even in poorly cooperative patients.
