目的 :探讨屈光不正性弱视对儿童双眼视及视觉诱发电位 (VEP)双眼总和的影响。方法 :对 2 0例正常儿童及 34例屈光不正性弱视儿童 (分有、无立体视两组 )进行全视野刺激视觉诱发电位的研究。结果 :双眼刺激视觉诱发电位总和VEP和单眼刺激视觉诱发电位AP10 0 :无立体视组明显低于正常组及有立体视组 (P <0 .0 1) ;有立体视组低于正常组 ,但差异无显著性 (P >0 .0 5 )。单眼刺激视觉诱发电位LP10 0 :屈光不正性弱视组较正常组明显延长 (P <0 .0 1) ,有、无立体视两组之间无差异 (P >0 .0 5 )。结论 :视觉诱发电位比行为或心理物理方法更为优越 ,能定量准确地客观反映视功能状态 ,视觉诱发电位双眼总和能客观评价屈光不正性弱视儿童双眼视。
Objective: To investigate the effect of refractive amblyopia on binocular vision and visual evoked potential (VEP) in children. Methods: Total visual field stimulation of visual evoked potentials was performed in 20 normal children and 34 children with amblyopia (divided, without stereopsis). Results: The total visual evoked potentials (VEP) and monocular stimulation visual evoked potentials (AP10 0) in both eyes were significantly lower than those in the normal group and the stereopsis group (P <0.01), and those in the stereopsis group were lower than those in the normal group But the difference was not significant (P> 0.05). Monocular stimulation of visual evoked potential LP10 0: ametropia amblyopia group was significantly longer than the normal group (P <0. 01), with and without stereopsis was no significant difference between the two groups (P> 0.05). CONCLUSION: Visual evoked potentials are more superior than behavioral or psychophysical methods, and can objectively reflect the state of visual function quantitatively and accurately. The sum of binocular visual evoked potentials can objectively evaluate binocular vision in children with ametropia amblyopia.
