摘要: 斜视弱视治疗前后的双眼视觉现象均有神经解剖生理学、心理物理学基础,其相互关联并印证。在注视方向的视界圆内,视网膜对应分为两个区,即双眼黄斑对应区和右眼颞侧视网膜与左眼鼻侧视网膜对应区,右眼的鼻侧视网膜与左眼颞侧视网膜对应区。这两个区域又分别对应传入的小细胞通路和大细胞通路。小细胞通路主要处理形觉、色觉和精细立体视觉,大细胞通路处理运动和空间信息及粗的局部立体视觉。加深和梳理这些相互连接有利于对双眼视觉的理解和进一步探讨。(眼科,2012, 21:297-301)

Abstract: There are interrelation among psychophysics, neuronal anatomy neurophysiology and clinical binocular vision phenomena. Based on neuronal anatomy, there are two corresponding area bilateral retina projecting at fixate direction of Vieth-Müller circle. There are corresponding area between binocular fovea, the temporal area of retina in right eye and nasal area of retina in left eye, the nasal retina in left eye  and the temporal retina in right eye. The two separated corresponding area projecte to the brain via different pathway. The  parvocellular pathway is mostly dealing with  formcolor and fine stereopsis. The magnocellular pathway is mostly dealing with movement space sign and granulate stereopsis. It is very helpful for our practice to understand the clinical binocular vision phenomena more deeply based on this neuronal anatomy. (Ophthalmol CHN,2012, 21:297-301)
