During Worth 4 Dot testing, if five dots are seen, what does this indicate?

Explanation:
Worth 4 Dot testing checks whether both eyes fuse a single image or if suppression or double vision is present. When the eyes fuse properly, you should see four dots. If one eye is suppressed, you typically see three dots because the image from that eye is not perceived. If there is flat fusion with no suppression, you still see four dots. Seeing five dots means there are two distinct images from the eyes that are not fused, i.e., diplopia. In other words, the extra dot reflects double vision rather than a single fused image or a suppressed eye.
