概括
植入式眼镜 (ICL) 手术增加了外周高视度失焦,特别是在部区域,在手术后一周内稳定下来. 这种效应在较高近视时更为明显.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 视网膜成像 视网膜成像
背景情况:
- 近视的进展可以持续到成年期,可能与外围高视度失焦与校正镜片有关.
- 植入式拼接镜头 (ICL) 有效地纠正中心折射误差,但它们对外围折射的影响不太了解.
- 了解ICL手术后的外周折射变化对于优化视觉结果至关重要.
研究的目的:
- 在ICL手术前后,测量视网膜各区域的折射差值 (RDV) 变化.
- 分析ICL植入物对外围折射误差的影响.
- 评估外周折射在早期术后期的稳定性.
主要方法:
- 一项前性研究,涉及40名患者的40只眼睛,这些患者接受了ICL植入用于近视.
- 在手术前,一周后和一个月后进行的RDV测量.
- 在不同的异常度 (0-15°,15-30°,30-45°,45-53°) 和部门 (上部,下部,部,鼻腔) 中分析RDV.
主要成果:
- 在ICL手术后观察到总RDV (TRDV) 和外围RDV (超过15°偏心) 的显著增加.
- 在所有四个部门 (上部,下部,部,鼻腔) 的外周RDV在术后显著增加.
- 外周折射变化在手术后一周稳定,在一个月的随访时没有显著差异.
- 与超高近视小组相比,较高近视小组表现出较大的外周折射转移变异.
结论:
- ICL手术诱导了外围高视度失焦状态,该状态在术后早期得到稳定.
- 超视失焦变化的幅度随着从中枢视网膜的异常度而增加.
- 时间视网膜区域在ICL植入后表现出最显著的外周折射变化.

01:16Focusing of Light in the Eye
1.5K
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...

01:28Angle Closure Glaucoma: Treatment
360
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...

01:25Glaucoma: Overview
465
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...
