  • Title: [Changes observed in electrophysiological investigations in amblyopia and strabismus].
    Author: Krzystkowa KM, Kubatko-Zielińska A, Wójcik E, Strek W, Lebiedź J.
    Journal: Klin Oczna; 1998; 100(4):229-34. PubMed ID: 9770983.
    Abstract:
    PURPOSE: The aim of the investigations was to state whether strabismic amblyopia and aniseiconia can be connected with disturbance of visual evoked potentials (VEP). MATERIAL AND METHODS: VEP investigations in 28 children with amblyopia, aged from 4 to 12 years and in 16 healthy persons were performed. Analysis of amplitude and latency of the positive wave P1 and negative wave N2 in the healthy eye and in the amblyopic eye was done. RESULTS: Statistical significance of the decrease of average amplitude of the fold in the record of the amblyopic eye at stimulation with small patterns was found. CONCLUSION: In amblyopia the amplitude of the pattern reversal VEP is decreased. Changes in the record of VEP in amblyopic eyes testify to the presence of transmission lesion in the retrobulbar visual pathway.
