- 折射手术是一种折射手术.
背景情况:
- 儿童的白内障手术需要仔细考虑折射误差的进展.
- 眼内透镜 (IOL) 植入是儿科白内障的一个常见程序.
- 了解长期的折射变化对于视觉发育至关重要.
研究的目的:
- 分析儿童初级IOL安置后5年折射误差的变化.
- 为了确定手术时的年龄如何影响折射误差的变化.
- 为了确定与IOL植入后的折射误差变化相关的因素.

- 参与者接受了白内障手术,并进行了初级IOL植入.
- 折射误差 (球体等效) 测量了5年,根据手术时的年龄和手术后的折射状态进行分析.
主要成果:
- 观察到显著的近视转移,较年轻儿童的转移更大 (例如,0至1岁儿童的-5.99 D与7至13岁儿童的-0.83 D).

Focusing 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...

Glaucoma: Overview
528
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...

Angle 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...

Open 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.
