BACKGROUND AND OBJECTIVE
Surgery on the rectus muscles may interfere with anterior segment perfusion. This study investigates the influence of combined rectus muscle surgery on the blood-aqueous barrier in children. Namely, the influences of tucking and resection procedures were compared.
PATIENTS AND METHODS
Laser flare measurements for tyndallometry were performed preoperatively and postoperatively in 25 children. Fifteen of the children had undergone a combination of a rectus recession and tucking; 10 had undergone a combined recession-resection procedure.
RESULTS
The mean preoperative flare value was 4.1 photon counts/ms versus 3.7 photon counts/ms postoperatively in the eyes that had undergone surgery. Statistical evaluation showed that the postoperative changes were insignificant. No significant difference was found between the two surgical techniques (tucking vs resection) regarding the preoperative versus postoperative flare value change (level of statistical significance .05).
CONCLUSION
Combined squint surgery, either recession-tucking or recession-resection, was not shown to influence the blood-aqueous barrier.
背景与目的
直肌手术可能会干扰眼前节灌注。本研究调查儿童直肌联合手术对血-房水屏障的影响。具体而言，比较了折叠术和切除术的影响。
患者与方法
对25名儿童在术前和术后进行激光散射测量以进行丁达尔ometry测量。其中15名儿童接受了直肌后徙术和折叠术联合手术；10名儿童接受了后徙-切除术联合手术。
结果
接受手术的眼睛术前平均闪光值为4.1光子计数/毫秒，术后为3.7光子计数/毫秒。统计学评估显示术后变化不显著。两种手术技术（折叠术与切除术）在术前与术后闪光值变化方面未发现显著差异（统计学显著性水平为0.05）。
结论
后徙-折叠术或后徙-切除术联合斜视手术均未显示会影响血-房水屏障。
