title: Anomalous head posture with early-onset homonymous hemianopia.
abstract: OBJECTIVE
  We have noted the frequent finding of an ipsilateral head turn in children with early-onset homonymous hemianopia. We report a series of patients with these findings and propose a theory to explain this association.
  
  
  METHODS
  Ten patients with early-onset homonymous hemianopia and anomalous head posture were examined. Head computed tomography and magnetic resonance imaging confirmed a cerebral lesion as the cause of the hemianopia in all patients.
  
  
  RESULTS
  All patients had onset of central nervous system disease prenatally or before age 18 months. A head turn toward the visual field defect with a gaze preference contralateral to the visual field defect was present in all patients.
  
  
  CONCLUSIONS
  Early-onset homonymous hemianopia should be included in the differential diagnosis of anomalous head posture.
