概括
虹膜 - 眼角 (ICA) 显著影响植入式眼镜 (ICL) 的放置. 较大的ICA与体下的触觉插入增加有关,影响镜片顶和位置.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 之前的细分分析.
背景情况:
- 准确预测植入式合镜头 (ICL) 顶需要了解后腔解剖学参数.
- 虹膜 - 眼角 (ICA) 和ICL圆顶之间确立了负相关性.
- 过大的ICA可能会导致ICL在体下面的触觉插入.
研究的目的:
- 为了研究虹膜 - 眼角 (ICA) 对可植入眼镜 (ICL) 触觉位置的影响.
- 为了确定ICA在植入后对ICL顶的影响.
- 分析ICA与从虹膜根到ICL触觉 (IRH) 末端的距离之间的关系.
主要方法:
- 一项前性观察性研究,涉及135名接受横向ICL植入的患者.
- 根据ICA测量结果,患者被分为三组:ICA1 (0-32°),ICA2 (32-64°) 和ICA3 (64-96°).
- 对包括IRH和vault在内的参数进行了相关性分析;用于估计IRH,使用了多重线性渐进回归模型.
主要成果:
- 在ICL库中,ICL库显示了ICA组的顺序下降 (P < 0.001),与ICA负相关 (P < 0.001).
- 与ICA1和ICA2相比,ICA3组的ICL触觉在纤毛体下插入的比例显著更高 (P = 0.039).
- 逐步回归确定ICA是影响IRH的主要因素 (β = 0.536,P < 0.001),其次是水平至的距离 (β = 0.348,P < 0.001).
结论:
- 太大的虹膜-眼角增加了可植入的眼镜在眼体下触觉插入的可能性.
- 增加虹膜-眼角与从虹膜根到ICL触觉端 (IRH) 的距离更大有关.
- 较大的虹膜 - 眼角与较小的ICL圆顶相关.

Angle Closure Glaucoma: Treatment
402
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...

Glaucoma: Overview
482
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...
