概括

反向瞳孔阻塞 (RPB) 影响了近三分之一的脑膜固定眼内透镜 (IOL) 患者. YAG外围虹膜切除术有效治疗RPB,降低虹膜擦伤,炎症和青光眼的风险.

科学领域:

眼科医生眼科眼科
医疗成像医学成像
手术技巧手术技巧

背景情况:

膜固定眼内透镜 (IOL) 在囊支不足时使用.
反向瞳孔阻塞 (RPB) 是IOL植入后的潜在并发症.
前段光学连贯断层扫描 (AS-OCT) 可以评估与RPB相关的眼睛参数.

研究的目的:

为了确定RPB的频率在患有膜固定性IOL的患者.
为了评估与RPB相关的AS-OCT参数.
评估YAG外围 iridotomy 在管理 RPB 的有效性.

主要方法:

对110名接受了膜固定内膜眼镜植入的患者进行了回顾性分析.
AS-OCT用于测量IOL倾斜,分散,前腔角 (ACA),前腔水深 (AQD) 和虹膜-IOL距离.
由虹膜-IOL距离≤0和ACA>70°定义的RPB.

主要成果:

在32名患者 (29%) 中发现了RPB.
对20名患有RPB的患者进行了YAG外周 iridotomy.
皮膜切除术后,平均ACA显著降低 (91.91°至61.02°),平均AQD降低 (4.67mm至4.31mm),平均虹膜-眼镜距离增加 (-0.09mm至0.33mm).

结论:

RPB发生在大约三分之一的眼睛中,在没有先前皮膜切除术的情况下,具有膜固定IOL.
YAG外周 iridotomy 是一个有效的治疗 RPB.
治疗可以降低二次并发症的风险,如虹膜擦伤,炎症和绿内障.

Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

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

Glaucoma: Overview

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

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...
