概括
与单视镜片 (SVL) 相比,非对称多点失焦技术 (AMDT) 眼镜镜片在12个月以上的儿童中显著减缓了近视的进展. AMDT透镜表现出良好的安全性,并减少了年龄对近视进展的影响.
科学领域:
- 眼科医生 眼科 眼科
- 眼镜测量是指眼睛的测量.
- 儿科眼科护理 儿科眼科护理
背景情况:
- 近视是一种常见的折射误差,引起越来越多的公众健康问题,特别是在儿童中.
- 有效的近视控制策略对于预防高近视和相关的眼部并发症至关重要.
- 眼镜镜片为近视管理提供了一种非侵入性的方法.
研究的目的:
- 评估非对称多点失焦技术 (AMDT) 眼镜镜片在控制近视进展方面的12个月疗效.
- 为了比较AMDT镜头与单视镜头 (SVL) 的近视控制效果.
主要方法:
- 一个双面膜随机对照试验,涉及144名8至13岁近视儿童.
- 参与者被随机分配到使用AMDT眼镜镜片或SVL.
- 在基线,6个月和12个月测量了循环球等效折射 (SER) 和轴长 (AL).
主要成果:
- 与12个月后的SVL相比,AMDT镜头显著降低了近视的进展,SER变化下降了74%, (-0.16 D vs. -0.50 D) 和AL变化下降了51% (0.17 mm vs. 0.32 mm).
- 年龄较小和轴延长速度较快之间的相关性在AMDT组中不那么明显.

01:16Focusing 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...

01:27Open Angle Glaucoma: Treatment
407
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
453
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
