title: On the positive correlation between the percentage of acute fracture of medial orbital wall and the degree of injury of affected medial rectus muscle by CT image.
abstract: OBJECTIVE
  To study the correlation between the percentage of acute fracture of unilateral medial orbital wall and the degree of injury of medial rectus muscle on the same side and to explore the possibility of evaluating the degree of injury of medial rectus muscle according to the percentage of fracture of medial orbital wall on the same side undergoing examination and diagnosis of ocular trauma by use of CT scan.
  
  
  METHODS
  To measure the span length of fracture of medial orbital wall, to calculate the fracture percentage, to measure the maximum widths of muscle belly of medial rectus muscle on affected and contralateral sides on CT images and to analyse statistically.
  
  
  RESULTS
  There is a significant positive correlation between the fracture percentage of medial orbital wall and the increase in amplitude of width of medial rectus muscle on the same side.
  
  
  CONCLUSIONS
  The injury of medial rectus muscle was aggravated by the greater percentage of fracture of medial orbital wall, which could be used to assess the degree of injury of medial rectus muscle suffering fracture of lamina orbitalis.
