Final answer:
In a Worth 4 Dot test, seeing only two or three dots can indicate strabismus, a condition where the eyes do not align properly. Seeing five dots suggests diplopia or double vision, another symptom of strabismus.
Step-by-step explanation:
In the Worth 4 Dot test, an individual is asked to view 4 dots (two red, one green, one white) with special glasses that have one red lens and one green lens. Resultant errors can indicate strabismus, a condition in which the eyes don't properly align with each other.
If the person has regular vision or fusion, they would see all four dots. However, if the person has suppression in one eye or strabismus, they may only see two dots (red) or three dots (two red, one green). The appearance of 5 dots would suggest diplopia or double vision, a symptom that also could indicate strabismus.
