The most common central types of spontaneous nystagmus are downbeat and upbeat, infantile, pure torsional, pendular fixation, periodic alternating, and seesaw nystagmus. 2011 Sep. 1233:320-6. This combination of unilateral optic neuropathy and asymmetric brainstem lesions occurring simultaneously at a time is rare, that is why UVPN is a rare entity but is possible in MS. Other diseases where optic nerve and brainstem lesions can be seen are syphilis, Wernicke's encephalopathy, few vasculitis syndromes, and neuromylitis optica, but cooccurrence of both the lesions at a time together is very uncommon.

The OKN drum also can reveal such a subtle reduction in adducting saccadic velocity. The https:// ensures that you are connecting to the Neurological disease should be suspected when the nystagmus is asymmetrical or unilateral. [15] However, the convergence, elevation, and depression on both eyes are usually intact. 2017;74(10):1216-1222. [18] The deficit in upgaze results in increased signal to other muscles, including the dominant medial recti, that manifest as a convergence and co-contractions of muscles that manifest as retraction.

Accessibility de Seze J, Lucas C, Leclerc X, Sahli A, Vermersch P, Leys D. One-and-a-half syndrome in pontine infarcts: MRI correlates. Internuclear ophthalmoplegia or ophthalmoparesis (INO) is an ocular movement disorder that presents as an inability to perform conjugate lateral gaze and ophthalmoplegia due to damage to the interneuron between two nuclei of cranial nerves (CN) VI and CN III (internuclear). Six cases were male and two cases were female. [38] Diffusion-weighted imaging with MRI may detect brainstem infarcts causing INO that may not be detected with T2-weighted imaging alone. The patients can be taught to move the head to compensate for the defective adduction. Examination of the eye movements and nystagmus can help differentiate the disorders of the central nervous system from the peripheral vestibular disorders; however, it is often not performed . Such abnormal vertical ocular movements include:[4], Usually, convergence is not affected even in the eye with adduction deficit in horizontal gaze.

The cardinal symptoms are, on the one hand, blurred vision, jumping images (oscillopsia), reduced visual acuity and, sometimes, double vision; many of these symptoms depend on the eye position. The authors examined five young children with monocular vision loss who developed monocular nystagmus. However, the absence of convergence does not rule out the diagnosis of INO. [18] Congenital nystagmus may be sub-classified into congenital motor nystagmus (presents with relatively normal vision, normal fundus, and normal neurological examinations) and congenital sensory nystagmus (presents with poor vision).

Dizziness is a common complaint of patients treated by primary care physicians. Nystagmus is clinically described based on amplitude, frequency, and direction of oscillations. This syndrome[19] consists of an INO in one eye combined with an ipsilateral CN VI fascicular involvement with sparing of the sixth nerve nucleus. 2000 Sep. 69:403-4. It can be jerk nystagmus where there is a slow drift of eyes and a quick corrective component, or pendular nystagmus, where eyes move with the same speed in both directions.
