title: A study of motion perception in primary open angle glaucoma.
abstract: OBJECTIVE
  To study the features of the motion perception (MP) and explore the worth of the clinical application of MP test in primary open angle glaucoma (POAG).
  
  
  METHODS
  MPs were recorded from 41 patients (67 eyes) with POAG ang 56 normal subjects (112 eyes) by the MP software in PC compatible computer. Meanwhile, the MP ways and MP sites were analyzed and MP abnormal rate was compared to the clinical parameters and the visual function indices related to glaucoma.
  
  
  RESULTS
  The results showed that the total abnormal rate of MP was 89.5% in POAG, and the abnormal rate was 81.6% in early stage of POAG, and MP abnormal degree had positive correlation with C/D, ocular tension and corrected loss variance (CLV), and negative correlation with visual acuity and mean sensitivity (MS), and no correlation with age and short-term fluctuation (SF) in the patients with POAG.
  
  
  CONCLUSIONS
  These results suggest that the MP test provides a newly effective examination method in diagnosing the early POAG.
