When does binocular diplopia arise?

Answer 1

Binocular diplopia arises when the eye movement in one direction is prevented, and is often a congenital (present at birth) condition. Binocular diplopia is usually caused by misalignment of the eyes.

Answer 2

Binocular diplopia typically arises due to misalignment of the eyes, which can be caused by conditions such as strabismus, cranial nerve palsies, or thyroid eye disease. This misalignment prevents both eyes from focusing on the same point, leading to double vision.
