We report a unique neuroophthalmological syndrome consisting of vertical 
one-and-a-half syndrome-resulting from a combination of supranuclear conjugate 
upgaze palsy associated with left infranuclear (fascicular) third nerve 
involvement (Weber syndrome)-with concomitant contralesional pseudo-abducens 
palsy. Magnetic resonance imaging confirmed that this unusual clinical 
combination was the result of two infarcts one in the left thalamomesencephalic 
junction and another affecting the left infrategmental paramedian area of the 
rostral midbrain. We discuss the clinical topography of both 
neuroophthalmological findings. This unusual neuroophthalmological finding has 
not been reported.
