  Perception of any single object as a single is achieved by the simultaneous use of both the eyes. This perception is termed as binocular single vision. If bifoveal fixation and normal retinal correspondence is involved, it is a normal binocular single vision but if there is the absence of the bifoveal fixation, which is usually with the abnormal retinal correspondence then it is the abnormal binocular single vison [1].

  Orthophoria is the condition wherein the visual axis of both the eyes directs to the point of fixation and do not show any deviation on being dissociated. In case wherein the visual axis of the two eyes fixates the point but shows deviation on being dissociated, it is termed as heterophoria or Non Strabismic Binocular Vision anomalies (NSBVA) [1]..
