  • Title: [The visual evoked potentials of non-amblyopic eyes in children with amblyopia].
    Author: Li S, Cai H, Guo J.
    Journal: Zhonghua Yan Ke Za Zhi; 1995 Nov; 31(6):422-5. PubMed ID: 8762568.
    Abstract:
    We investigated the characteristics of visual evoked potentials (VEPs) of the eyes with normal visual acuity in 84 children of whom 20 were normal, 28 of anisometropic amblyopia, 8 of anisometropic amblyopia already cured, 8 pairs of monozygotic and 6 pairs of dizygotic twins with amblyopia. The results showed that although the fellow eye of an amblyopic eye or the cured amblyopic eye had normal visual acuity, the VEPs presented abnormal, the marked abnormality being the prolongation of the latency of P100 peak. No significant difference was found in VEPs between the eye with normal visual acuity and the eye with amblyopia in the monozygotic twins with the same genetic background (P > 0.05). This study demonstrated that possibly the clinical examinations of visual acuity and VEPs reflect different visual information processes, and the "normal" eyes of amblyopes are not normal.
