Movement No spontaneous or elicited eye movement Skew or Conjugate Gaze Deviation: At rest, one or both eyes are either positioned up or to the left/right, rather than midline Dysconjugate Gaze: eyes do not move together in the same direction Roving: slow, conjugate, lateral, back and forth eye movements Oculocephalic Reflex None: eyes move in If your eyes feel like they're darting back and forth without any attempt on your part to move them, it's time to get to your doctor ASAP.

This can cause the brain to swell, which can block the circulation of blood and oxygen to the brain. Nystagmus typically is accompanied by reduced visual acuity and depth perception, and it can affect balance and coordination. Upward rolling of the eyes (with reflexive eyelid closure) on corneal stimulation implies that the pons and midbrain are intact (the reflex pathway involves the trigeminal nerve, the spinal CN5 nucleus, the lateral brainstem tegmentum, and the CN3 and CN7 nuclei — if necessary revise the Brainstem Rules of 4). Eye movements seen in the comatose patient include: Most individuals have a degree of exophoria when drowsy for any reason and any underlying strabismus tends to worsen — thus dysconjugate gaze is difficult to interpret in the stuporose or comatose patient.

Normally, rhythmic eye movements called nystagmus occur consisting of an alternating slow phase with slow pursuit movements in the direction of strip movement, and a rapid phase with quick refixations back to midline. Your eyes are in constant motion. The presence of a dysconjugate ocular deviation in coma (horizontal, vertical, or oblique misalignment) often indicates a cranial nerve palsy or skew deviation. Hence they can be distinguished clinically. You also have the option to opt-out of these cookies.

Nystagmus is the medical term used to describe involuntary eye movements.These eye movements may be side-to-side (lateral nystagmus), up and down (vertical nystagmus), or rotary. In such cases, instead of the voluntary – guided and commanded – eye movements, the reflex ones should be checked. The movements may be very subtle, very prominent, or somewhere in between.
