概括
氧化 (HCQ) 的使用与外核层 (ONL) 稀薄有关,这是视网膜毒性的早期迹象,甚至在症状出现之前. 这一发现表明,ONL厚度是监测HCQ诱导的视网膜损伤的潜在生物标志物.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜成像 视网膜成像
- 药理学 药理学是指药理学的学科.
背景情况:
- 氧化 (HCQ) 是一种常见的治疗自身免疫性疾病的方法.
- 使用HCQ会带来视网膜毒性的风险,查方法仍在发展.
- 光学连贯断层扫描 (OCT) 显示出早期检测视网膜损伤的前景.
研究的目的:
- 调查HCQ摄入量与外核层 (ONL) 稀释之间的关联.
- 评估ONL稀释作为HCQ视网膜病变的潜在生物标志物.
- 评估在没有明显视网膜毒性的情况下患者的ONL变化.
主要方法:
- 一项涉及20名HCQ使用者和20名年龄相匹配的对照者的病例控制研究.
- 通过图表审查和全面的眼科评估收集的数据.
- 使用光学一致性断层扫描 (OCT) 分析了80只眼睛.
主要成果:
- 与对照组相比,HCQ治疗的患者表现出显著较小的周围膜,膜和整体ONL (P < .001).
- 在多个视网膜象限中观察到ONL稀释,特别是在下部区域.
- 累积的HCQ剂量显示,在特定区域与ONL稀释的相关性很弱.
结论:
- 在HCQ使用者中,外核层 (ONL) 厚度显著降低,不管明显的视网膜毒性.
- 这项研究是第一个在眼睛中证明这种关联的研究,具有负的HCQ视网膜病变查.
- ONL厚度成为HCQ视网膜毒性的潜在早期诊断指标.

Photoreceptors and Visual Pathways
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,...

Glaucoma: Overview
527
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...
