Vertical Gaze Palsies from Medial Thalamic Infarctions without Midbrain Involvement Stroke 26:1467-1470, Clark,J.M.&Albers,G.W., 1995 See this aricle in Pubmed Article Abstract Three patients with acute paralysis of vertical gaze were imaged with MRI. Sagittal T1 and axial T1,T2,and proton-weighted images were obtained.All three patients had repeated scans performed from 3 days to 6 weeks after the original study.Two patients exhibited unilateral right thalamic infarcts(polar and paramedial territory),and one patient had a bilateral paramedian thalamic infarction.There was no evidence of midbrain involvement on any of the images.Vertical gaze palsies are known to be produced by lesions of the rostral interstitial medial longitudinal fasciculus.This MRI study reveals thalamic infarctions without associated midbrain infarctions in three patients with vertical gaze palsies.This may be explained by interruption of supranuclear inputs.
