概括
急性不补偿性心力衰竭 (ADHF) 会导致视网膜微血管结构的暂时变化. 光学连贯断层扫描血管学 (OCT-A) 可以监测这些可逆变化,有助于评估心力衰竭患者的血液动力状况.
科学领域:
- 眼科医生 眼科 眼科
- 心脏病学 心脏病学
- 医疗成像医学成像
背景情况:
- 急性不补偿性心力衰竭 (ADHF) 是一种影响心血管功能的严重疾病.
- 视网膜微血管结构的改变可能反映出全身血动力学变化.
- 像OCT-A这样的现代成像技术为微血管动力学提供了新的见解.
研究的目的:
- 在ADHF期间调查视网膜微血管结构的动态变化.
- 将ADHF患者的视网膜微血管与健康对照进行比较.
- 评估心脏补偿后这些变化的可逆性.
主要方法:
- 住院患有ADHF的成年患者在入院24小时内和出院前接受了包括OCT和OCT-A在内的全面眼科检查.
- 进行了跨胸腔心声学和生物标志物分析 (NT-proBNP).
- 为了进行比较,纳入了一个不患心脏或视网膜疾病的年龄匹配个体的对照组.
主要成果:
- 与对照组相比,ADHF患者在入院时表现出视力衰弱,黄斑血管密度降低, perfusion密度改变.

01:25Glaucoma: Overview
528
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

5.9K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...
