title: Effects of scleral buckling on the retrobulbar haemodynamic changes.
abstract: OBJECTIVE
  This study was planned to investigate blood flow changes due to scleral buckling surgery. In addition the effects on these changes of factors related to patient characteristics and operative technique were studied.
  
  
  METHODS
  Central retinal artery (CRA) and ophthalmic artery (OA) blood flow velocities were studied with colour Doppler ultrasonography after scleral buckling surgery in 25 patients with unilateral rhegmatogenous retinal detachment. The effects of the patient's age, referral time, aetiological factors, operative technique, cryotherapy width and buckling distance on the haemodynamic changes were noted.
  
  
  RESULTS
  Buckling surgery reduces the blood flow velocities in the CRA, but affects OA blood flow less. Encircling is found to be responsible and it is greater in patients with anatomical success. Other factors do not have any significant effect on these changes.
  
  
  CONCLUSIONS
  Good anatomical and functional results can be achieved despite these haemodynamic changes. It must be kept in mind that these changes may cause complications in some patients and the surgery must be minimized.
