It is still unclear whether the contralateral line bisection error in unilateral homonymous hemianopia is caused by the visual field defect, strategic oculomotor adaptation or by additional extrastriate brain injury. We therefore simulated hemianopia in healthy participants using a gaze-contingent display paradigm and investigated its effects on manual and ocular line bisection performance and ...

Unilateral oculomotor nerve palsy can result from various neurological disorders. We herein report the case of a 68-year-old man with complete unilateral oculomotor nerve palsy following campylobacter infection. Based on the antecedent infection and the patient's decreased tendon reflexes, incomplete Miller Fisher syndrome (MFS) without ataxia was suspected. His serum tested positive for anti-G...

We longitudinally assessed the development of oculomotor control in reading from second to fourth grade by having children read sentences with embedded target words of varying length and frequency. Additionally, participants completed oculomotor (pro-/anti-saccades) and linguistic tasks (word/picture naming), the latter containing the same item material as the reading task. Results revealed a 3...

Delayed postoperative oculomotor nerve palsy is a rare complication that occurs in the setting of microsurgical aneurysm clipping. While a number of theories have been postulated to explain the development of delayed postoperative oculomotor nerve palsies, the underlying pathophysiology of such complications still remain to be elucidated. In this report, we present a case of delayed postoperati...

Contradictory results have been reported about the inhibitory input to the medial rectus subdivision of the oculomotor nucleus of the cat. In the present ultrastructural study, we quantified the GABAergic and glycinergic terminals in the various subdivisions of the rabbit oculomotor nucleus with the use of post-embedding immunocytochemistry combined with retrograde tracing of horseradish peroxi...

Isolated third cranial nerve palsies in head trauma patients can be the result of direct or indirect damage to the oculomotor nerve. They are usually associated with severe head trauma. We reported a case of isolated oculomotor nerve palsy associated with minor head injury. No initial loss of consciousness was recalled. Computed tomography (CT), magnetic resonance imaging (MRI), and magnetic re...

That patients with Parkinson's disease may have abnormalities of oculomotor function is fairly well known by clinicians. Limitation of gaze, especially in the vertical plane, and inadequate convergence have been described previously (Krebs 1925; Bielschowsky 1935). The present report is of a systematic investigation of oculomotor dysfunction among patients with this disease to determine: (1) th...

CLINICAL CASE A 58 year-old man with a known diagnosis of a large cell lung carcinoma, developed a progressive diplopia. His examination revealed a double oculomotor nerve palsy with dilated and poorly reactive pupils. A cranial magnetic resonance showed an unique and solitary lesion in the midbrain, which presumably affected to both oculomotor nucleus and fasciculus. There were not found addit...
