When the right optic tract and/or the right (occipital lobe of the ) cerebral cortex is damaged, left hemianoposia, namely loss in the left side of the right eye and in the left side of the left eye, takes place.
 
右の視索を構成する神経線維は,右視神経の外側にあり視交叉で交叉しなかった線維と,左視神経の内側にあり視交叉で交叉した線維とである.右視神経の外側にある神経線維は,右側眼球網膜の耳(外)側半分から来る.左視神経の内側にある神経線維は,左側眼球網膜の鼻(内)側半分から来る.右側眼球網膜の耳(外)側半分の視野は右側眼球の鼻(左,内)側である.左側眼球網膜の鼻(内)側半分の視野は左側眼球の耳(左,外)側である.


When the right optic tract and/or the right (occipital lobe of the) cerebral cortex is damaged, left hemianoposia, namely loss in the left side of the right eye and in the left side of the left eye, takes place.


The fibers composing the right optic tract are fibers from the outer half of the right eye retina, for which the visual field is the left (inner) half of the right eye, as well as fibers from the inner half of the left eye retina, for which the visual field is the left (outer) half of the left eye.
