概括

在儿童中,间歇性外观 (IXE) 往往与血液有关,而不仅仅是高视. 这项研究发现,透是IXE患者最常见的折射误差,挑战了以前的假设.

科学领域:

眼科医生眼科眼科
儿科眼科医生儿科眼科医生
斯特拉比斯姆研究研究

背景情况:

间歇性外otropia (IXE) 是一个常见的童年斜视,特别是在 2-4 岁.
IXE与折射误差的关系是复杂的,并未完全理解,而异于食热症与视高的联系.
以前的研究表明IXE和近视之间存在潜在的联系,但这需要进一步调查.

研究的目的:

调查被诊断为间歇性异质 (IXE) 的儿童中折射误差的患病率和分布.
挑战视和视障之间传统的关联.
探索折射误差对IXE患者近视发展的潜在贡献.

主要方法:

一项涉及179名患有IXE的儿科患者的横截面回顾性研究.
折射误差的评估是使用自重折射计和循环扩张后的视网膜镜.
数据分析利用IBM SPSS V.26来确定出血,近视和高视的患病率.

主要成果:

凝视是最常见的折射状况 (38%),其次是低超视 (35.8%) 和低近视 (22.3%).
中度至高的近视和远视不太常见,分别影响了5.5%和5%的患者.
观察到两只眼睛的低和对称折射误差趋势.

结论:

这项研究发现,IXE的儿童患有更高的血液缩率,这与传统的观点相矛盾,即视主要与高视障碍有关.
这些发现表明,出血在IXE中是一个显著的折射状态.
结果表明,需要针对IXE和相关折射误差的儿童制定量身定制的治疗策略.

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...

Accessory Structures of the Eye

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

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,...

Muscles of the Eye

Muscles of the Eye

The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...
