The noninvasive laser Doppler technique was used to study retinal circulatory characteristics in five patients who underwent uncomplicated scleral buckling procedures. In each patient, the systolic/diastolic variation of the red blood cell speed in the retinal arteries (flow pulsatility ratio) was lower in the eye that had received an intrascleral implant and an encircling band than in the fellow eye. In one patient, an increase in flow pulsatility ratio accompanied an increase in retinal blood flow after removal of the scleral buckling elements. In another patient, the flow pulsatility ratio in the eye that had received a solid implant and an encircling band was less than the ratio in the fellow eye that had received an absorbable implant alone. Our results indicated that reduced retinal blood flow may be common after scleral buckling procedures, and may be a significant factor in otherwise inexplicable postoperative complications.
采用非侵入性激光多普勒技术研究了5例接受单纯巩膜扣带术患者的视网膜循环特征。在每例患者中,接受巩膜内植入物和环扎带的眼内视网膜动脉中红细胞速度的收缩期/舒张期变化(血流搏动率)低于对侧眼。在1例患者中,去除巩膜扣带元件后,血流搏动率增加伴随视网膜血流量增加。在另一例患者中,接受实心植入物和环扎带的眼内血流搏动率低于仅接受可吸收植入物的对侧眼。我们的结果表明,巩膜扣带术后视网膜血流量减少可能很常见,并且可能是术后出现无法解释的并发症的一个重要因素。
