概括

中部前腔深度 (CACD) 随轴长 (AL) 增加,与透镜厚度 (LT) 反相关,与白至白距离 (WTW) 呈正相关. 较短的眼睛具有较小的CACD和更厚的镜头.

科学领域:

眼科医生眼科眼科
之前的细分分析.
生物识别仪表是如何使用的

背景情况:

前段尺寸对于眼睛健康和手术结果至关重要.
了解中央前腔深度 (CACD) 的决定因素对于管理像闭角玻璃眼这样的疾病至关重要.
轴长 (AL) 是一个关键参数,但其与其他前段指标的关系需要进一步阐明.

研究的目的:

调查CACD和其他前段生物识别参数之间的关联.
为了确定不同眼睛长度 (短,正常,长) 的CACD的决定因素.

主要方法:

从300名手术前的白内障患者 (50-80岁) 的生物识别数据的回顾性审查,白内障和主要的角度闭合疾病或老年白内障.
测量包括使用Lenstar光学生物识别的AL,CACD,LT,CCT和WTW.
患者被分为短 (AL ≤22毫米),正常 (AL = 22-26毫米) 和长 (AL ≥26毫米) 的眼睛组.

主要成果:

在短眼中,CACD和WTW最小,在AL中增加.
与正常和长眼相比,短眼的透镜厚度 (LT) 在短眼中显著增加.
逐步回归确定AL,LT和WTW是与正常眼睛中CACD相关的独立因素;LT和WTW是短眼和长眼中的关键因素.

结论:

与AL一起,CACD增加,达到26毫米以上的峰值.
CACD显示了与LT的反相关性和与WTW的正相关性.
较小的WTW导致镜头重新定位,减少CACD,这在角度闭合疾病管理中很重要.

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...

Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

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...
