Abstract
Effect of Ocular Deviation on Stereopsis
Highlights
Stereopsis is the third grade of Binocular Single vision
Individuals with any other systemic disease(specially which can affect study), Individuals with any other Ocular Pathology, with any active ocular infection, any ocular anomalies like corneal scar etc,ocular deviation if less than 10 degree and Significant amount of amblyopic patient were excluded from the study
Stereopsis was measured with Titmus Fly Test
Summary
Stereopsis is the third grade of Binocular Single vision. Stereopsis occurs due to disparity of an object. It is not always mandatory that Stereopsis is always associated with three dimensional objects [3]. It occurs when two dimensional objects is offset horizontally. Due to this offset depth perception is created. Pannum Fusional Area is considered as an in front and behind the horopter to some extent [4,5]. It is steeper centrally and flatter peripherally. In case of ocular deviation, images of an object are displaced from the foveal region to parafoveal region and due to cone cell variation stereoscopic range will be varied [6,7]
