可注射式交联透明质酸钠在小梁切除术中的作用

目的研究注射交联透明质酸钠后的滤过泡形态特征和作用。方法将患者随机分成2组,每组25例(25眼),其中一组在术毕滤过泡下注射交联透明质酸钠(试验组),另一组常规缝合结膜(对照组)。观察术后并发症;测量术后1周、1个月、3个月、6个月的眼压;采用各时间点裂隙灯照像评分作为参比标准,用前节OCT扫描滤过泡,观察滤过泡形态,并记录滤过泡的横径、纵径、高度、泡壁厚度。结果试验组在术后早期并发症较少。术后1周试验组眼压:(10.5±4.6)mmHg(1kPa=7.5mmHg),对照组(9.2±4.4)mmHg(P=0.305);术后1个月试验组眼压(9.7±2.7)mmHg,对照组(11.2±5.3)mmHg(P=0.221);术后3个月试验组眼压(10.8±3.8)mmHg,对照组(13.8±6.3)mmHg(P=0.047);术后6个月试验组眼压(11.6±4.9)mmHg,对照组(15.2±5.2)mmHg(P=0.037)。在各个时间点裂隙灯照像评分中试验组滤过泡的高度、弥散范围、血管生长都显著优于对照组。在各个时间点前节OCT扫描显示试验组滤过泡的横径、纵径、高度都显著大于对照组,泡壁厚度无显著差异,但是部分滤过泡显示为包裹型。结论注射交联透明质酸钠后滤过泡更加隆起、弥散,而泡壁厚度没有明显变化。注射交联透明质酸钠在一定程度上减少术后低眼压、浅前房和滤过泡瘢痕化等并发症的发生,且术后3～6个月时眼压控制较好。

Effect of injectable crosslink sodium hyaluronate in trabeculectomy

Objective To investigate the morphological features and effects of the blebs implanted with injectable crosslink sodium hyaluronate in trabeculectomy. Methods All patients were randomly divided into 2 groups,25 cases(25 eyes) in each group.The experimental group received sub-conjunctival injection of crosslink sodium hyaluronate after the operation;The control group received regular suturation of conjunctiva.The complications were observed after operation.The intraocular pressure of each group at 1 week,1 m...
