Internuclear ophthalmoplegia is characterised by restricted ocular motility in lateral gaze in which the affected eye shows impairment of adduction and it results from damage to medial longitudinal fasciculus (MLF). Wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) is an extremely rare neurological manifestation which has typical signs including primary gaze exotropia, vertical gaze palsy, ptosis, abducting nystagmus. The common and serious etiological factor is cerebrovascular accident involving the vessels supplying MLF and many cases have life threatening associated neurological impairment. In this case report we have discussed about a gentleman who presented with bilateral ptosis, primary gaze exotropia and headache. Patient found to have vertical gaze palsy and abducting nystagmus on examination. Computed tomography (CT) imaging shows infarct in pontine region and CT angiography revealed basilar artery occlusion supplying region of pons with involvement of posterior cerebral artery. Patient treated with antiplatelet and diplopia managed. Patient showed improvement on subsequent follow-up visits.

Chronic relapsing inflammatory optic neuropathy (CRION) is a recently described form of recurrent isolated subacute optic neuropathy, with accumulating evidence that it is a nosological distinct entity. The condition is highly responsive to systemic steroid treatment and prone to relapse on steroid withdrawal. Diagnosis and management of this condition is often challenging. This 33-year-old lady with family history of multiple sclerosis (MS), with uniocular visual loss of her right eye since 2 years old without apparent cause, presented with reduction of vision and loss of colour vision in the left eye, associated with painful eye movement. There was internuclear ophthalmoplegia but slit lamp examination were unremarkable. She had no other related sensory or motor symptoms. Magnetic resonance imaging (MRI) did not reveal any features of MS. Aquaporin-4 antibody, anti-MOG and gene testing for Leber’s hereditary optic neuropathy were all negative. Metabolic, infective, and other autoimmune causes were also excluded. Visual evoked potential studies of left eye showed a mild reduction in amplitude with no prolongation of latency. Her multiple optic neuritis recurrences were treated with intravenous steroids followed by tapering regime of oral prednisolone with good effect. Knowledge of this rare condition as part of the differential diagnoses of possible aetiologies of optic neuropathy is important among Ophthalmologists, as prompt diagnosis and steroid treatment helped reduce the associated risk of blindness. Multiple relapses after initial successful treatment of inflammatory optic neuropathy should raise the suspicion of CRION.International Journal of Human and Health Sciences Supplementary Issue-2: 2021 Page: S19

A 48-year-old woman presented with sudden-onset altered sensorium 2 days after a snake bite (unidentified species) and was found to have a large right frontal intracerebral haemorrhage (ICH) with transtentorial herniation (TTH) causing brain stem compression. A day later, neurological examination revealed internuclear ophthalmoplegia (INO) fitting the clinical description of wall eyed bilateral INO syndrome. INO is a rare ocular motor sign, the most common causes being brain stem infarction, haemorrhage or demyelinating disease. It rarely acts as a false localising sign, such as in this case, and in an even rarer cause for ICH, that is, haemotoxic snake bite without initial evidence of coagulopathy. An emphasis needs to be laid on detailed physical examination, often considered a lost art nowadays, to help detect subtle clinical signs which could herald ominous complications of conditions like TTH and help in early diagnosis and treatment of the same.

Eight-and-a-half syndrome is a rare entity characterised by conjugate horizontal gaze palsy, ipsilateral internuclear ophthalmoplegia and ipsilateral lower motor neuron type facial palsy. It is due to a lesion affecting median longitudinal fasciculus, paramedian pontine reticular formation and facial nerve fascicle on the same side at the level of pons. The diagnosis is easily missed as it needs detailed ocular movement examination. It is mainly caused due to infarction or demyelinating conditions. We are reporting an interesting case of a 54-year-old man with right-side eight-and-a-half syndrome due to acute ischaemic stroke and ST-elevation myocardial infarction of the inferior wall.
