概括
在儿童身上植入 retropupillary iris-claw 眼内透镜 (IOL) 的结果比前置固定更好. 后皮膜固定导致内皮细胞损失较少,并发症较少,使其成为儿科阿法基亚的更安全选择.
科学领域:
- 眼科医生 眼科 眼科
- 儿科眼科医生 儿科眼科医生
- 眼内透镜植入 眼内透镜植入
背景情况:
- 儿童的阿法基亚往往需要眼内透镜 (IOL) 植入.
- 不足够的囊支为IOL固定带来了手术上的挑战.
- 虹膜爪眼镜在囊支受到损害时提供了替代的固定方法.
研究的目的:
- 为了比较前置与后置皮膜虹膜爪 IOL 植入的结构和视觉结果.
- 评估这两种固定技术的安全性和有效性,用于患有囊支不足的儿科眼睛.
主要方法:
- 一项前性随机研究,涉及32名儿科阿法基眼睛,囊支持不足.
- 眼睛被随机分配到前置或后置虹膜-爪 IOL 固定.
- 包括视力敏度,折射,内皮细胞密度,角膜厚度,眼镜内侧倾斜和集中在内的结果措施在1,6个月和12个月后进行了评估.
主要成果:
- 两个小组在12个月后都显示出视力敏度的改善,前视线和后视线固定之间没有显著差异.
- 前部固定导致12个月的中央内皮细胞密度 (CECD) 在统计学上显著下降 (17.4%的细胞损失),而不是 retropupillary固定 (5.6%的细胞损失).
- 像瞳孔阻塞和前腔炎症这样的并发症在前固定组中更为频繁,前固定组也表现出明显较浅的前腔.
结论:
- 在1年的随访中,与前置固定相比,后置皮膜虹膜爪内膜眼镜固定显示出更优异的内皮细胞保存.
- 前部固定与较高的炎症反应发生率,瞳孔阻塞和较浅的前腔有关.
- 逆毛皮膜固定似乎是一个更安全,更有效的方法,用于虹膜爪内腔镜植入儿科aphakic眼睛与不足的囊支.

Angle Closure Glaucoma: Treatment
1.1K
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
1.2K
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
951
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.
