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)
