[A pattern-ERG study of amblyopia].
26 normal and 60 amblyopic children were examined with the P-ERG. The results showed that P-ERG in amblyopes was significantly abnormal, with delay in the latent periods of wave b and the after potential, as well as reduction in the amplitudes of the same. The latency of wave a was also delayed in some severe amblyopes. The abnormal manifestations of P-ERG and the mechanism in their occurrence were discussed. The P-ERG could be a sensitive and objective diagnostic method for amblyopia.
