概括
停止抗血管内皮生长因子 (VEGF) 治疗新血管与年龄相关的黄斑变性 (nAMD) 可能会改变流体模式. 甲状腺下液体显著减少,而甲状腺内液体在停止治疗后增加.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 视网膜疾病 视网膜疾病
背景情况:
- 神经血管与年龄相关的黄斑变性 (nAMD) 是导致视力丧失的主要原因.
- 抗血管内皮生长因子 (抗VEGF) 治疗是nAMD的标准治疗方法.
- 在停止治疗期间了解流体动力学对于管理nAMD至关重要.
研究的目的:
- 在停止抗VEGF治疗后,调查nAMD中复发性流体的数量和分布.
- 分析下液 (SRF) 和内液 (IRF) 量的变化.
- 评估无处理间隔对nAMD中的液体积累的影响.
主要方法:
- 追溯纵向观察性研究,使用来自"抗击视网膜失明"的数据! 登记. 登记. 登记. 登记. 登记. 登记. 登记. 登记. 登记.
- 纳入标准:以前没有接受过治疗的nAMD,≥3次抗VEGF注射,≥6个月停止治疗,以及复发性流体.
- 使用深度学习算法 (维也纳流体监测器) 量化流体.
主要成果:
- 分析了56名患者的56只眼睛 (平均年龄为76.29±6.58岁).
- 从基线到第一个无治疗间隔结束时,SRF体积显著下降 (58.0nl至8.73nl,p<0.01).
- 在第一个无治疗间隔期间,IRF体积和色素上皮质脱落 (PED) 变化在统计学上没有显著意义. 在第二次停产后,IRF数量超过了SRF数量.
结论:
- 停止抗VEGF治疗可以改变nAMD中的流体模式.
- 观察到SRF的减少,但在治疗停止后,IRF可能会随着时间的推移而增加.
- 需要进一步的研究来了解这些流体变化的长期影响.

Pulse rhythm
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...

Autoregulation of Blood Flow
Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
Chemical Signaling in Autoregulation
Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation.
