[Use of neural networks for analysis of visual evoked potentials developing a type of "pattern"--preliminary report].

PURPOSE

The authors present the "pattern" visual evoked potentials (VEP) analysis with use of the artificial neural networks (ANN).

MATERIALS AND METHODS

The study involved 11 patients with compressive chiasmal optic neuropathy, 20 patients with optic neuritis, 12 patients with anterior ischaemic optic neuropathy, 20 patients with optic nerve atrophy from neuritis, 8 patients with demyelinative neuropathy, 5 patients with oedema optic nerve, 20 healthy persons. The tests of visual evoked potentials were performed with the use of computer system UTAS-E1000. Classification of potentials was made by correlation of outputs of ANN with results of confirmed neuro-ophthalmology conditions.

RESULTS

ANN of different architecture were classified correctly in 80-100% of VEP record samples.

CONCLUSIONS

The obtained correctness of classification confirms usefulness of VEP analysis as the objective diagnostic method in some neuro-ophthalmological diseases and indicates application of ANN in multifactor analysis.
