[An investigation of the multi-channel VEP topography by full field stimulation in functional amblyopia of children].
37 children of functional amblyopia and 40 normal children were examined with the multi-channel VEP topography by full field pattern reversal stimulation. The average results of esotropia showed a "half field stimulation effect", or an asymmetric distribution, in the amblyopic eyes, and a minor "half field stimulation effect" also existed in the nonamblyopic fellow eyes. However, the "half field stimulation effect" did not appear in both the amblyopic and non-amblyopic fellow eyes in anisometropic amblyopia. The findings suggest that (1) the pathological mechanism may be different between esotropic and anisometropic amblyopia, and (2) the non-amblyopic eye in esotropic amblyopia may not actually be "normal".
