概括
在高近视时,晶状镜片的对齐决定了白内障手术后眼内镜片的位置. 虽然眼内镜片比较分散,但通常不会影响视觉质量.
科学领域:
- 眼科医生 眼科 眼科
- 生物医学光学 生物医学光学
- 解剖学研究 解剖学研究
背景情况:
- 高近视在白内障手术中提出了独特的挑战.
- 了解晶状透镜 (CLL) 和眼内透镜 (IOL) 之间的位置关系对于最佳的视觉结果至关重要.
- 前段光学连贯性断层扫描 (AS-OCT) 为这些评估提供了精确的测量.
研究的目的:
- 通过AS-OCT研究眼内透镜 (IOL) 和晶状透镜 (CLL) 之间的位置关系.
- 分析高近视和白内障眼中的两种透镜的倾斜和分散.
- 确定影响这些患者内腔眼镜位置的因素.
主要方法:

- 排除具有眼科病史影响区域,瞳孔扩张不良或手术并发症的病例.
- 通过AS-OCT测量CLL和IOL倾斜和分散,CLL厚度,前腔深度和轴长度.
主要成果:
- 高近视 (HM) 眼睛与凝视 (EM) 眼睛相比,CLL倾斜和分散显著增加 (p<0.01).
- 在HM和EM组中,IOL分散率明显高于CLL分散率 (HM的p<0.01,EM的p=0.043).
- 在这两组中,CLL对齐是IOL位置的唯一显著预测因素 (R2值在0.097到0.476之间,p<0.01).
结论:

Focusing 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...

Glaucoma: Overview
1.5K
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...

Open 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.

Angle 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...
