Clinical findings of eight-and-a-half syndrome

Isolated Eight and Half Syndrome, a Rare Neuro-ophthalmic Presentation: A Case Report

“…Neuro-ophthalmic entities are usually caused by brain stem ischemic stroke (vascular), demyelination disease like multiple sclerosis. 7 Some space occupying lesions like tuberculoma, cavernoma, and tumors have also been reported representing one and half or eight and half syndrome. 8…”

Eight-and-a-Half Syndrome as The First Presentation of Unknown Metastatic Primary Tumor

“…The treatment is directly correlated with the underlying condition as well as neurorehabilitation [1,2]. Commonly, facial palsy is the first to improve followed by the ocular symptoms [1].…”

“…The treatment is directly correlated with the underlying condition as well as neurorehabilitation [1,2]. Commonly, facial palsy is the first to improve followed by the ocular symptoms [1]. Recovery tends to be incomplete for those with a vascular-related EHS and almost complete for those of non-vascular etiology [3].…”

“…Recovery tends to be incomplete for those with a vascular-related EHS and almost complete for those of non-vascular etiology [3]. Time to onset of symptoms might suggest the cause, as for instance sudden onset can favor ischemic stroke [1,2]. Current literature emphasizes the importance of etiological assessment [3].…”

“…Eight-and-a-half syndrome (EHS) is a rare pontine neuroophthalmic syndrome consisting of conjugate horizontal gaze palsy, ipsilateral internuclear ophthalmoplegia and ipsilateral peripheral facial nerve palsy [1,2]. The most common etiology is ischemic stroke; less common etiologies are demyelinating lesions and space occupying lesions [3].…”
