A vertical gaze palsy (VGP) is a conjugate, bilateral, limitation of the eye movements in upgaze and/or downgaze.
What is a vertical gaze?
Vertical gaze palsy refers to the condition in which neither eye moves fully upward or downward. In contrast to horizontal gaze, there are no clinical disorders in which vertical gaze palsy is caused by cerebral hemisphere disease.
What does upward gaze palsy mean?
In upward vertical gaze palsies, the pupils may be dilated. When people with this palsy look up, they have nystagmus. That is, their eye rapidly moves upward, then slowly drifts downward. Parinaud syndrome is an upward vertical gaze palsy.

Where is the vertical gaze Centre located?
midbrainThe vertical pathway lives at the junction of the thalamus and the midbrain, the thalamomesencephalic junction. The vertical gaze center lives in the midbrain and in the connection between the thalamus and the membrane, the thalamomesencephalic junction-- the thalamomesencephalic junction.
What causes downward gaze palsy?
[6] Ipsilateral downward gaze palsy was due to ipsilateral riMLF lesion. It interrupted the ipsilateral projections to the eye depressor muscles. The contralateral upward gaze palsy was probably due to injury to the premotor fibers innervating contralateral elevator muscles due to thalamic lesion.
Can stroke cause gaze palsy?
Gaze palsies are commonly observed in the setting of acute stroke; such strokes are nearly always localized to either cerebral cortical or brainstem areas. Much less common are lesions localized at the subcortical pathways involved in the control of eye movements.
Is palsy Parkinson's?
Progressive supranuclear palsy (PSP) is not Parkinson's disease (PD), but is a Parkinsonian-like syndrome. PSP is a rare brain disorder that causes serious and progressive problems with gait and balance, as well as eye movement and thinking problems.
What does left gaze palsy mean?
In most cases, the gaze palsy can simply be seen by inability to move both eyes in one direction. However, sometimes a patient exhibits an abduction nystagmus in both eyes, indicating evidence of a conjugate gaze palsy. A nystagmus is a back and forth "jerk" of the eye when attempting to hold a gaze in one direction.
Why do eyes deviate to side of stroke?
Conjugate eye deviation In the case of a right-sided stroke in a patient with a left-dominant brain, signals from the right brain to the left eye are disrupted, whereas signals from the left brain to the right eye continue to work (Fig. 2 and Fig. 3).
What does left gaze palsy mean?
In most cases, the gaze palsy can simply be seen by inability to move both eyes in one direction. However, sometimes a patient exhibits an abduction nystagmus in both eyes, indicating evidence of a conjugate gaze palsy. A nystagmus is a back and forth "jerk" of the eye when attempting to hold a gaze in one direction.
What is meant by Disconjugate gaze?
Definition. Dysconjugate gaze is a failure of the eyes to turn together in the same direction.
What causes gaze deviation in stroke?
In the case of strokes, restriction of horizontal gaze on one side is usually due to damage of the contralateral frontal cortex or ipsilateral pontine area.

Parinaud's syndrome is an inability to move the eyes up and down. It is caused by compression of the vertical gaze center at the rostral interstitial nucleus of medial longitudinal fasciculus (riMLF). The eyes lose the ability to move upward and down. It is a group of abnormalities of eye movement and pupil dysfunction. It is caused by lesions of the upper brain stem and is named …

· Thus, a trochlear nerve palsy causes an ipsilateral higher eye (i.e., hypertropia) and excyclotorsion (the affected eye deviates upward and rotates outward). Patients may report vertical and/or torsional diplopia that is usually worse on downgaze and gaze away from the affected side. Anatomy. There are several clinically significant features of the trochlear nerve …

· This type of deviation can be differentiated from a true vertical muscle paresis in several ways: 1) The ocular rotations do not show substantial limitations or overactions of the vertical eye muscles, as seen with vertical muscle pareses. 2) Patients with an oblique muscle palsy tend to have a substantial difference in the vertical deviation between right and left gaze. …

· Misalignment is most often vertical, but can also be horizontal and torsional. Palsy refers to a complete weakness of a muscle while a paresis is a partial weakness. This condition is usually unilateral (one eye) but can be bilateral (both eyes). In bilateral cases, it may asymmetrically affect one eye more than the other.

· The superior rectus acts in all fields of gaze, and the inferior oblique helps elevate when the eye is turned inward. The inferior rectus and superior oblique muscles are responsible for downward vertical movement. The inferior rectus acts in all fields of gaze, and the superior oblique helps elevate on medial gaze.
