- 生物医学成像学 生物医学成像学
背景情况:
- 先天性白内障是婴儿视力障碍的主要原因之一.
- 早期发现和了解风险因素对于及时干预至关重要.
- 透镜厚度尚未被广泛研究,作为小儿白内障的潜在指标.
研究的目的:
- 确定0-5岁儿童的透镜厚度和先天性白内障之间的关联.
- 评估使用超声波生物显微镜 (UBM) 测量镜片厚度的可行性.
主要方法:
- 进行了一项前性,多中心的病例控制研究.
- 从0-5岁的118名参与者 (171只眼睛) 参与了这项研究.
- 在342张图像上使用超声波生物显微镜 (UBM) 测量了镜片厚度.
主要成果:
- 在没有白内障的眼睛中,平均镜片厚度为3.60 ± 0.17毫米,而在白内障眼睛中为3.16 ± 0.61毫米 (P < 0.0001).
- 镜片厚度<3.5毫米与0-7个月大的婴儿白内障的几率增加显著相关 (调整后OR=5.99).

Focusing of Light in the Eye
2.6K
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...

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
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...
