概括
标准和加速角膜交叉链接 (CXL) 对于角膜,在角膜密度测量和雾中显示了类似的结果,超过9个月. 这两种方案都有效地降低了角膜的不透明度,在手术后的前三个月,短暂的雾达到顶峰.
科学领域:
- 眼科医生 眼科 眼科
- 角膜外科手术 角膜外科手术
- 生物医学工程 生物医学工程
背景情况:
- 角膜是一种渐进的角膜疾病,导致视力受损.
- 角膜交叉链接 (CXL) 是一种治疗方法,可以阻止角膜的进展.
- 标准和加速的CXL协议存在,在UVA暴露时间和强度上有所不同.
研究的目的:
- 为了比较角膜密度度变化后标准与加速CXL在渐进的角质患者.
- 评估CXL协议在控制角膜不透明和雾方面的有效性.
主要方法:
- 三十八名患有渐进式角质的患者被分成两个平等的组.
- 一组接受标准CXL (30分,3mW/cm2UVA);另一个接受加速CXL (10分,9mW/cm2UVA).
- 用Scheimpflug成像测量角膜密度在基线和手术后的1,3,9个月.
主要成果:
- 加快CXL组的患者年龄大得多.
- 在CXL后9个月,加速组显示出更高的中部和后部角膜密度计.
- 在调整了年龄和基线值后,在密度计中没有发现显著的跨组差异;这两种方案都减少了角膜不透明度.
结论:
- 标准和加速CXL协议都会诱导暂时的角膜雾,可以通过增加密度计在前三个月内进行测量.
- 术后角膜雾的发病和恢复动态在标准和加速CXL之间是可比的.
- 角膜密度测量变化表明,CXL两种方案在治疗角质的治疗中具有可比的长期疗效.

01:05Mechanism of Ciliary Motion
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

01:13Contact Angle
When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive force...
