[Differential diagnosis of amblyopia and retrobulbar neuritis with electroophthalmologic methods].
The electroretinogram (ERG), the brightness visual evoked cortical potential (H-EP) and the pattern reversal visual evoked cortical potential (M-EP) were recorded from 7 patients with amblyopia and 5 patients with neuritis retrobulbaris. The ERGs and the H-EPs of the amblyopic eyes were normal whereas the amplitude of the M-EP was significant diminished. The parameters of the ERG recorded from the patients with neuritis retrobulbaris showed normal values, however the H-EPs were significantly decreased and the peaktimes were delayed. Also a decrease in the amplitudes of the M-EPs was noticed. This method is a usefull clinical contribution in the differential diagnosis between amblyopia and neuritis retrobulbaris.
