概括
在患有超视异观症的儿童中,眼睛越是超视的,与眼睛不太超视的相比,眼睛的轴延伸速度越慢. 这种差异在双盲眼中尤其明显,影响了折射发育.
科学领域:
- 眼科医生 眼科 眼科
- 儿科光学测量 儿科光学测量
- 眼部发展 眼部发展
背景情况:
- 超视异视异视,一个眼睛远见明显超过另一只眼睛的情况,会影响儿童的视觉发育.
- 了解眼部部件的纵向变化对于管理折射误差和预防盲视至关重要.
研究的目的:
- 为了比较球体等效折射 (SER) 和眼睛生物识别元件的纵向变化,在患有高视异常视度的儿童中,更高视度 (MoreH) 和更低视度 (LessH) 的眼睛之间.
- 调查眼对这些发育变化的影响.
主要方法:
- 对36名患有高视异观的儿童 (4至<13岁) 进行了前性纵向研究.
- 测量SER,轴长度 (AL),前腔深度 (ACD),镜片厚度 (LT) 和角质测量 (K).
- 线性混合效应建模用于比较MoreH和LessH眼睛之间的眼部部件变化速率.
主要成果:
- 与LessH眼相比,MoreH眼的SER变化较慢 (-0.11 D/年),而LessH眼的SER变化较慢 (-0.31 D/年).
- 在MoreH眼中,轴延长 (AL) 和AL/CR比率明显较慢.
- 异视度随着年龄的增长在眼儿童中增加,但在非眼儿童中减少.
结论:
- 在患有高视度异视眼的儿童中,较高视度眼睛的轴延长比较低视度眼睛的轴延长进展缓慢.
- 莫尔眼睛的这种较慢的延长在眼症的病例中尤其明显.
- 这些发现突出了高视异视异视的眼睛生长模式差异,这对视觉发育和管理策略有影响.

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...

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...
