Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

6.1K
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,...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

2.9K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Glaucoma: Overview01:25

Glaucoma: Overview

595
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...

  • 医疗成像医学成像
  • 玻璃眼研究研究 玻璃眼研究

背景情况:

  • 短视眼睛与马周环缩和周环稳形瘤呈现复杂的结构变异.
  • 在高近视症中,了解后部胆内腔位 (PICCs) 的存在及其对视觉功能的影响至关重要.

研究的目的:

  • 分析近视眼中的视野缺陷 (VFDs),有或没有PICCs.
  • 确定有PICC和没有PICC的眼睛之间有区别的因素 (组合).

主要方法:

  • 光学连贯断层扫描用于根据PICCs的存在或不存在对眼睛进行分类.
  • 视野缺陷使用汉弗里场分析仪3 (SITA标准) 进行评估.
  • 卵性指数 (OI),状膜缺陷 (LCDs) 和它们的分布被分析并使用多变量逻辑回归来比较组之间.

主要成果:

  • 具有PICC的眼睛显示VFD的患病率明显高 (65%) 与组合相比 (p < 0.001).
  • 后部内腔 (PICCs) 和薄膜形缺陷 (LCDs) 主要发生在下部 (B部门).
  • 在具有PICC的眼睛中观察到明显较低的平均卵度指数 (OI),被确定为唯一显著的区分因素 (p < 0.001).

结论:

  • 具有PICCs的眼睛中较低的平均OI表明结构变化的分级,可能解释VFD的较高比例.
  • 皮克斯的内时间主导性表明它在高近视症中青光眼的诊断不确定性中的作用.
  • 由于PICC和LCD的比例很高,下部对近视眼损伤的脆弱性需要进一步调查.
