概括
在先天性外眼镜 (CEL) 患者中,三片眼内透镜 (IOL) 与一片眼内透镜相比,显示出更大的倾斜和分散. 更长的轴长 (AL) 也与内视镜倾斜变化相关,需要仔细选择和监测内视镜.
科学领域:
- 眼科医生 眼科 眼科
- 生物医学工程 生物医学工程
- 手术创新 在外科创新.
背景情况:
- kongenital ectopia lentis (CEL) 带来了独特的外科手术挑战.
- 穿膜接固定眼内透镜 (IOL) 植入是CEL视力康复的常见方法.
- 了解IOL稳定性对于长期的视觉结果至关重要.
研究的目的:
- 研究眼内镜片 (IOL) 倾斜和分散的特征和相关因素.
- 在CEL患者中,在经皮膜 suture 固定后,比较三片和一片 IOL 之间的 IOL 稳定性.
- 为了确定影响IOL倾斜和分散的纵向变化的因素.
主要方法:
- 分析了一组61名CEL患者的队列,这些患者接受了跨关节固性IOL手术.
- 患者根据植入的IOL类型进行分组:三片IOL或一片IOL.
- 术后3个月和1年内测量了IOL倾斜和分散,并进行了多变量回归分析.
主要成果:
- 与一片IOL相比,三片IOL在手术后3个月和1年都表现出明显更大的水平和垂直倾斜.
- 三组IOL组在3个月到1年之间显示出更大的纵向倾斜和水平分散的变化.
- 较长的轴长度 (AL) 与内视镜倾斜的纵向变化有关,而三块内视镜与水平分散的纵向变化有关.
结论:

01:28Angle Closure Glaucoma: Treatment
1.4K
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...

01:27Open Angle Glaucoma: Treatment
1.1K
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.

01:16Focusing of Light in the Eye
6.7K
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...
