Isolated third nerve palsy develops in numerous intracranial pathologies such as closed head trauma, tumor, and aneurysm. Isolated oculomotor nerve palsy caused by shrapnel injury is uncommon. After a penetrating intracranial shrapnel injury, our patient with oculomotor ophthalmoplegia underwent surgery. Microsurgery removed the shrapnel that was applying pressure on the third nerve, resulting ...

Eye movement behavior is variable, and the brain's oculomotor circuitry may not always function consistently. In a recent fMRI study, Ozyurt and Greenlee (2011) correlated the activation strength of cortical and striatal brain regions with inter- and intraindividual variability in saccade performance. We discuss the design and implications of this study with regard to the differences between in...
