What does diplopia mean?
Answer:
Diplopia means double vision.
It is usually caused by a misalignment between the two eyes when the image of the object you are looking at falls on different areas of the retina in each eye. As a result the object is perceived in two different places and therefore is seen double.
However, it can also be caused by a structural problem in one eye – for example if a cataract is present, leading to diplopia in one eye only.
