- 折射手术是一种折射手术.
- 角膜断层扫描 角膜断层扫描 角膜断层扫描
背景情况:
- 眼部残留性白症 (ORA) 是折射性和前角膜白症之间的差异.
- 高ORA可能会对激光折射手术的结果产生负面影响.
- 了解ORA与基线折射误差的关系对于手术规划至关重要.
研究的目的:
- 为了研究基线折射误差和眼部残留纹症 (ORA) 的程度之间的相关性.
- 为了确定更高的近视或球形等效是否与增加的ORA有关.

主要方法:
- 从折射手术候选人的181只眼睛进行了回顾性分析.
- 进行 Corneal 断层扫描 (Pentacam AXL 波) 和显而易见的主观折射.
- 矢量分析用于计算ORA,并使用统计测试 (斯皮尔曼,ANOVA,Chi-square) 来评估相关性.
主要成果:

Focusing of Light in the Eye
2.9K
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...

Open Angle Glaucoma: Treatment
479
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.
