In Worth 4 Dot testing, seeing five dots indicates what?

Explanation:
Worth 4 Dot testing uses red-green glasses to uncover how the eyes are working together at the test distance. When fusion is normal, you should see four dots: a red dot, a green dot, and two white dots (the white dots are seen by both eyes). If one eye is suppressing, the dot that belongs to that eye won’t be seen, so you’ll typically count three dots—the dot from the non-suppressed eye plus the two white dots. If the eyes are not aligned and diplopia occurs, the white dot that should be seen by both eyes is perceived twice, giving you five dots in total. That extra dot signals that the brain is receiving two distinct images rather than a single fused image.
