Definition

Dysconjugate gaze is a failure of the eyes to turn together in the same direction.

Current Knowledge

Vision

Normal coordinated movement of the eyes produces conjugate gaze, in which the eyes are aligned for binocular three-dimensional vision. Misalignment results in loss of this vision. With the visual axis of each eye fixated on a different point, diplopia (or double vision) usually results and may be perceived as a blurred image if the two images are very closely aligned. However, if the image from the weaker eye is suppressed by higher cortical centers, there is only one image with loss of visual acuity (or a blurred image).

Pathology

Pathology usually resides either in the oculomotor muscles or their neuronal pathways, including the medial longitudinal fasciculus, the paramedian pontine reticular formation, the medullary reticular formation, the superior colliculus, or the cranial nerves III, IV, or VI, or their respective nuclei. It may result from a...
