title: [Large hang-back recession of superior rectus muscles as effective treatment of patients with dissociated vertical deviation].
abstract: OBJECTIVE
  The aim of this study is to report the results of large bilateral superior rectus hang-back recession in patients with dissociated vertical deviation.
  
  
  METHODS
  Retrospective analysis of patients with dissociated vertical deviation treated in the Department of Ophthalmology between 2011 and 2013. Our enrolment criteria included vertical strabismus angle over 15Δ and the absence of inferior or superior oblique overaction in patients who underwent bilateral superior rectus recession ranging from 8 mm to 12 mm. The surgical outcomes were evaluated.
  
  
  RESULTS
  Nine patients at the age of 14 to 46 years were included in the study. The mean vertical angle of deviation in the non-dominant eye was 22.8Δ ± 5.3Δ. The mean amount of recession was 9.8 ± 1.4 mm.
  
  
  CONCLUSIONS
  Large bilateral hang-back recession of the superior rectus muscles effectively reduces the vertical angle in patients with dissociated vertical deviation without concomitant oblique muscle overaction. dissociated vertical deviation (OVO), strabismus surgery, large recession of superior rectus muscles.
