概括

实时手术内光学相干断层扫描 (i-OCT) 在先前失败的descemetopexy复杂病例中成功引导了Descemet膜 (DM) 重定位. 这种先进的成像技术改善了所有患者的解剖结果,为具有挑战性的脱离提供了强大的解决方案.

科学领域:

眼科医生眼科眼科
医疗成像医学成像
角膜外科手术角膜外科手术

背景情况:

脱落膜脱落 (DMD) 可能是具有挑战性的管理,特别是在未成功的手术尝试后.
以前的descemetopexy失败通常是由于DM粘附,刚性或残留材料等因素造成的.
有效地重新定位Descemet膜对于视觉恢复至关重要.

研究的目的:

评估实时手术内光学相干断层扫描 (i-OCT) 在提高Descemet膜 (DM) 重定位率方面的疗效.
评估i-OCT在管理先前失败的descemet膜脱落 (DMD) 复杂病例中的实用性.
使用i-OCT识别以前重新定位故障的原因.

主要方法:

病历和前段i-OCT图像的回顾性审查,用于DMD重新定位失败的患者.
对i-OCT结果的分析,以确定之前手术失败的原因.
在复杂的DMD案件中,利用i-OCT指导用于随后的DM重新定位程序.

主要成果:

所有16名被纳入的患者 (复杂的DMD,1-3次先前尝试) 在i-OCT指导下成功实现了DM重新定位.
发现的常见故障原因包括残留粘弹性,DM粘附和DM刚性.
在最佳校正视敏度,中角膜厚度和眼内压力方面,经手术后显著改善.

结论:

实时i-OCT对于在失败的descemetopexy的情况下进行DM重新定位是非常有效的.
通过i-OCT,可以进行精确的外科手术,从而改善复杂DMD的解剖结果.
需要对更大的队列进行进一步的研究,以探索i-OCT在眼科手术中的更广泛潜力.

关键词:

在Descemet膜脱落时出现脱落.这就是descemetopexy.在外科手术期间,外科外科手术的外科外科外科外科外科.

Real Time RT-PCR

Real Time RT-PCR

Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
The real-time quantification of the number of amplified products is...

Hypothesis: Accept or Fail to Reject?

Hypothesis: Accept or Fail to Reject?

The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null...

Overview of Advanced Functional Groups

Overview of Advanced Functional Groups

Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
The table below summarizes some of the major functional groups in organic chemistry.

Extraction: Advanced Methods

Extraction: Advanced Methods

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Real Number System

Real Number System

The real number system includes all numbers used for counting, measuring, and comparing quantities. Natural numbers are the basic counting numbers: 1, 2, 3, and so on. Integers expand this set by including zero and negative whole numbers: ..., –3, –2, –1, 0, 1, 2, .... Rational numbers are those that can be expressed as the ratio of two integers m/n, where n≠0. This includes fractions like 1/2, integers such as 46, and decimals that terminate, such as 0.17, or...
