概括
在初级视角闭眼光眼 (PACG) 中,trabeculectomy后的法化会影响眼睛的血形态和眼内压力 (IOP). 使用粘性缓冲剂可保持血栓结构,但与传统的化相比,并不能改善IOP控制.
科学领域:
- 眼科医生 眼科 眼科
- 玻璃眼的手术 玻璃眼的手术
- 白内障手术 手术 白内障手术
背景情况:
- 在患有初级角闭眼光病 (PACG) 的患者中,在轨道切除术后经常进行法化.
- 发光乳化对运行良好的白内障切除术和随后的眼内压力 (IOP) 控制的形态的影响需要进一步研究.
- 术内操作的潜在保护作用,例如使用粘性来阻断内硬化,在bleb形态上还没有很好地确立.
研究的目的:
- 为了评估发泡乳化对PACG患者的trabeculectomy bleb形态和IOP控制的影响.
- 评估使用高密度粘性弹性 (粘性) 阻断内部硬化体的手术内阻断是否会改变这些效应.
主要方法:
- 一个单中心,前性,干预性研究包括PACG患者,他们在trabeculectomy后接受了发泡乳化.
- 患者被分为两组:A组在发酵过程中接受了粘性,而B组没有.
- 使用印第安纳布勒布外观分级尺度 (IBAGS) 和前段光学连贯性断层扫描 (AS-OCT) 评估了布勒布形态;在多个手术后的时间点记录了IOP和玻璃眼药物的使用.
主要成果:
- 在PACG患者中,法菌化显著降低了IOP和对抗白内障药物 (AGM) 的需求.
- 粘性缓冲组显示IOP的减少较小,相比传统的发酵化组.
- 虽然粘性组保持了更好的血栓形态 (高度,程度,反射性,小囊),但传统的发酵使血栓血管性增加,并在手术后的最初四个月内更好地控制了IOP.
结论:
- 在PACG眼中经过先前的轨道切除术时使用粘性在发酵过程中保留了血栓形态,但不会增强IOP的减少.
- 传统的发泡乳化,尽管导致了一些简单的形态变化,如身高降低和血管性增加,但在早期的术后期间导致了优异的IOP控制.
- 建议进行进一步的长期跟踪,以了解血栓形态变化的最终命运及其功能影响.

Angle Closure Glaucoma: Treatment
438
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
516
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
395
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.
