One and a half syndrome
Journal Title: Medpulse International Journal of Ophthalmology - Year 2017, Vol 3, Issue 1
Abstract
The one and a half syndrome is a rare ophthalmoparetic syndrome characterized by "a conjugate horizontal gaze palsy in one direction and an inter-nuclear ophthalmoplegia in the other". The most common manifestation of this unusual syndrome is limitation of horizontal eye movement to abduction (moving away from the midline) of one eye with no horizontal movement of the other eye. Nystagmus is also present when the eye on the opposite side of the lesion is abducted. Convergence is classically spared as Cranial Nerve III (oculomotor nerve) and its nucleus is spared bilaterally
