科学领域:

眼科医生眼科眼科
生物医学工程生物医学工程

背景情况:

长视障碍的分类对于有效的手术决策至关重要.
现有的方法可能无法完全捕捉长视眼镜的功能和结构变化.

研究的目的:

根据客观镜片的功能和结构参数,开发一种新的视近视的分类系统.
为了帮助手术决策对长视障碍的纠正.

主要方法:

一项涉及176名患有长视障碍的患者 (352只眼睛) 的横截面观察研究.
透镜功能通过功能障碍透镜指数 (DLI) 进行评估;透镜密度使用Pentacam (LD-P) 和扫描源OCT (LD-S) 进行测量.
主要成分分析 (PCA) 和k-means集群用于将眼睛分为非透镜手术 (NLS) 和透镜手术 (LS) 组;开发了一个诊断评分系统和网站.

主要成果:

268只眼睛 (76.1%) 被诊断为患有长视.
PCA排除了前5.2%的高度变化的病例.
138只眼睛 (51.5%) 被归类为NLS组,116只眼睛 (43.3%) 被归类为LS组.
在LS组显示显著较低的DLI和更高的镜片密度 (P<0.001).
确定了最优的截止值:DLI=7.75,LD-P=8.75,LD-S=60.05. 这就是最好的截止值.
将DLI和LD-P结合起来,产生了最高的诊断效果.

结论:

已经提出了使用透镜功能 (DLI) 和结构 (密度) 特征的长视的新型分类.
这种分类提供了一种有价值的诊断工具,以指导对长视的手术干预.

Focusing of Light in the Eye

Focusing of Light in the Eye

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

Photoreceptors and Visual Pathways

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

Glaucoma: Overview

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...
