目的　观察左旋多巴对猫弱视眼模型的作用 ,以探讨弱视的发病机理。方法　对 1 4只猫斜视性弱视模型 ,分别以左旋多巴 2 0mg/kg ,4 0mg/kg ,安慰剂 3组灌胃给药 ,观测猫的图形视觉诱发电位。结果　左旋多巴能一定程度地缩短猫斜视性弱视眼的P10 0 波峰潜时及提高P10 0 波幅值。结论用左旋多巴对猫斜视性弱视模型灌胃给药 1 2周 ,能一定程度地改善其弱视眼的传导和感觉功能 Objective To observe the effect of levodopa on amblyopia in cats and to explore the pathogenesis of amblyopia. Methods Strabismus amblyopia model of 14 cats was administered by intragastric administration of levodopa 20mg / kg, 40mg / kg and placebo respectively. The visual evoked potential of the cat was observed. Results Levodopa could shorten the P10 0 peak latency and increase the amplitude of P10 0 in strabismic amblyopia. Conclusion L-Dopa to strabismus strabismus amblyopia model administration for 12 weeks, to some extent, to improve the conduction and sensory function of amblyopic eyes
