What causes binocular diplopia?

Why should the images fall on non-corresponding parts of retina?

The images fall on non-corresponding parts of the retina, because of mis-alignment of the eyes.

This mis-alignment may be in the primary position or when patient looks in to one direction.

Diplopia will not occur in cases of long standing misalignment because brain learns to suppress one image: eg congenital squint. Hence, diplopia is a symptom of a recent acquired misalignment.
