【摘要】 目的:探讨视神经中的由中枢投向视网膜的中枢性纤维在视觉功能中的调节作用。方法:制作单眼视神经离断家兔模型,切断中枢性纤维与视网膜的联系,但同时不损伤视网膜血循环系统,运用视觉电生理的手段观察手术眼与非手术眼视网膜电图(ERG)和视觉诱发电位(VEP)的变化。结果:手术前后之手术眼以及术后手术眼与非手术眼的ERG的变化之间无统计学意义。结论:中枢性纤维在视觉功能中的调节作用很微弱。更多还原

【Abstract】 Objective:To investigate the role of the center fiber influence the visual function.Methods:The optic nerve of one eye was cut, but not to damage circle system of retina wasn’ t trauma . Change of ERG and VEP between operation eyes and non-operation eyes were observed through visual electrophysiology.Results:Changes of ERG in operated eyes do not make statistical difference at pre-and post-operation.Conclusions:The function of the center fiber has weak effects upon vision function.更多还原
