Surgical peripheral iridectomies occluded by vitreous, exudation or omission of peripheral iridectomy during cataract operation were the most common causes.

周边虹彩切除处被玻璃体、渗出物覆盖或手术时没有做周边虹彩切除术是发生瞳孔阻塞最常见的原因。

Although 25 eyes presented with acute angle closure glaucoma, 6 eyes were insidious onset and asymptomatic. While 27 eyes relieved pupillary block after laser iridotomy or surgical peripheral iridectomy, 4 eyes required vitrectomy or laser photomydriasis to relieve pupillary block. Five eyes (16%) developed chronic angle closure glaucoma due to peripheral anterior synechia. one could be controlled by chronic medical therapy, three required trabeculectomy, the another one even required cyclocryotherapy because poor IOP control after trabeculectomy.

虽然大多数的病例（25只眼）以急性发作为临床表徵，但有6只眼为隐袭性，无任何临床症状。27只眼经雷射虹彩瞳孔术或外科周边虹彩切除术后可以解除瞳孔阻塞，另4只眼无法解除而需作玻璃体切除术或雷射光瞳孔放大术。5只眼(16%)因周边前黏连发生慢性隅角闭锁性青光眼，其中1只眼可以药物控制，3只眼需做小梁切除术，另1只眼做小梁切除术后眼压仍无法控制而接受睫状体冷冻治疗。

The research result shows that the flowability, moldability, cohesiveness of high performance concrete of hill sand are significant by comparison with ordinary concrete on mechanical properties, long term properties, and durability. Motar flowability decreases with the increase of single-mixed active additive. The flowability can be largely improved by double mixing of active additive and super plasticizer NF. This is because not only the active additive has filling effect but also the dispersing effect induced by surface action between additive and super plasticizer NF. And the optimal content of materials are: super plasticizer NF≥0.8%, fly ash 20%, PS 20~30%,zeolite powder≤20%,SF 5~8%; The negative influence of hill sand powder should be avoided by controlling of powder content and the use of active additive and super

研究表明：随着单掺活性掺合料掺量的增加，砂浆流动性减小，活性掺合料与萘系高效减水剂NF双掺使用，比使用同样剂量萘系高效减水剂NF的基准浆体流动性明显增大，这是由于玻璃体材质活性掺合料不仅有填充效应，更主要的是它与高效减水剂之间的表面物化作用产生了分散性，而活性掺合料对浆体的流化作用效果主要是依赖于其分散性；能有效改善胶砂流动性的适宜掺量为：萘系高效减水剂不小于0.8%，粉煤灰掺量为20%，PS掺量为20~30%，沸石矿粉掺量不宜大于20%，SF掺量为5~8%；通过对粉末含量的限制，并借助活性掺合料、高效减水剂的合理使用，就可以避免山砂粉末含量的负面影响，配制出密实度高，抗渗性能优异，具有良好的耐久性能，并具有良好的体积稳定性的山砂高性能混凝土。
