Internuclear ophthalmoplegia (INO) is a deficit in the control of conjugate eye movements, which results from damage to the medial longitudinal fasciculus (MLF). The MLF carries internuclear neurons to connect nuclei of the brain stem, including the nucleus of the abducens nerve (cranial nerve VI) in the pons to the contralateral subnucleus of ...
Internuclear ophthalmoplegia (INO) is due to a lesion of the medial longitudinal fasciculus (MLF) between the 3rd and 6th cranial nerve nuclei, resulting in impaired adduction of the ipsilateral eye and abducting nystagmus with contralateral gaze. Because the right and left MLF are in close proximity, bilateral INO can occur.
Contributor: Christopher Kirkpatrick, MD. Internuclear ophthalmoplegia (INO) is caused by disruption of the medial longitudinal fasciculus (MLF) which is a nerve fiber bundle that connects the sixth cranial nerve (CN VI) nucleus on one side of the pons to the medial rectus subnucleus of the third cranial nerve (CN III) in the contralateral ...

Please see the following video as a demonstration of thalamic esotropia in the setting of bilateral internuclear ophthalmoplegia (INO). COURSE For evaluation of the worst headache of his life, a CT of the brain without contrast was obtained which revealed a subarachnoid hemorrhage (See Figure 2A).
Diagnosis: Spinocerebellar ataxia with ophthalmoplegia. There are at least 30 different types of spinocerebellar ataxias (SCA) also referred to as autosomal dominant cerebellar ataxias (ADCA). These are divided into three categories based on they're typical presentation (See Table 2 below).
The cause of diplopia, oscillopsia, and anomalous head posture in this patient was a combination of dorsal midbrain syndrome and bilateral superior oblique palsy. This patient developed an idiopathic brainstem hemorrhage that extended from the ponto-mesencephalic junction upto the cerebral peduncles involving the rostral midbrain.
