Instead of seeing singly with two eyes, there is then double-vision (diplopia).
If no binocular fusion exists, then all possibility of diplopia is excluded.
At the beginning of 1880, I was informed that from time to time periodic squint had occurred with diplopia.
For a long time tendency to convergent squint, which is combined with diplopia, has existed on the left side.
diplopia continued to exist; single vision was only now and then possible for a short time.
diplopia is present in the whole visual field with increase of the deviation towards the right.
Another defect of vision may be next noticed; namely, diplopia, or double vision.
Two of Dalwig's patients developed a functional torticollis to avoid the diplopia caused by a superior strabismus.
Several patients complained of diplopia during the febrile stage, and one asserted that every object appeared fourfold to him.
