概括

在XEN凝支架植入后,过泡中的更大的内腔与较低的眼内压力 (IOP) 相对应. 前段光学连贯性断层扫描 (AS-OCT) 有助于分析血栓形态和预测IOP结果.

科学领域:

眼科医生眼科眼科
医疗成像医学成像
玻璃眼的手术玻璃眼的手术

背景情况:

植入XEN凝支架是一种手术选择,用于控制青光眼中的眼内压力 (IOP).
过血栓形态对于手术成功至关重要,但其内部结构并不总是被充分理解.
前段光学连贯性断层扫描 (AS-OCT) 可提供眼睛结构的高分辨率成像.

研究的目的:

为了研究XEN凝支架植入后的过斑的内部形态.
确定与术后眼内压 (IOP) 相关的形态因素.
评估AS-OCT在手术后评估血特征中的实用性.

主要方法:

在XEN凝支架植入后的6个月和1年内,AS-OCT成像用于分析18只眼睛的过斑.
测量了包括血栓高度,内腔高度,壁厚和上皮厚在内的定量参数.
眼睛根据存在 (内部腔组) 或缺乏 (统一组) 独特的内部腔的情况进行分类.

主要成果:

50%的眼睛 (9/18) 呈现出明确的内腔,而另外50%的眼睛呈现出均的斑块结构.
与均组相比,内腔组在6个月和1年后都显示出明显较低的术后IOP.
更高的血栓高度和更高的内腔高度与手术后的IOP有负相关性.

结论:

在XEN凝支架植入后,AS-OCT是分析过斑形态的宝贵工具.
血栓内内腔的存在和高度与改善的IOP控制有关.
优化血栓形态,特别是培养内腔,可以提高XEN支架手术的外科结果.

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...

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...
