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.
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.
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.
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.
本研究旨在调查巩膜扣带手术引起的血流变化。此外，还研究了与患者特征和手术技术相关的因素对这些变化的影响。
对25例单侧孔源性视网膜脱离患者在巩膜扣带手术后采用彩色多普勒超声检查视网膜中央动脉（CRA）和眼动脉（OA）的血流速度。记录患者年龄、转诊时间、病因、手术技术、冷冻疗法宽度和扣带距离对血流动力学变化的影响。
扣带手术降低了CRA的血流速度，但对OA血流的影响较小。发现环扎是造成这种情况的原因，并且在解剖学成功的患者中影响更大。其他因素对这些变化没有任何显著影响。
尽管存在这些血流动力学变化，但仍可取得良好的解剖和功能结果。必须牢记，这些变化可能在某些患者中引起并发症，并且手术必须尽量减少。
