概括

轨道切除术显著降低了初级开角玻璃眼患者的眼内压力和局部药物使用,改善了角膜透明度. 手术后,角膜密度计正常化,与健康对照相匹配.

科学领域:

眼科医生眼科眼科
玻璃眼研究研究玻璃眼研究
角膜生理学角膜生理学

背景情况:

主要开角青光眼 (POAG) 是不可逆转失明的主要原因.
垂眼切除术 (trabeculectomy) 是一种手术程序,用于降低青光眼患者的眼内压力 (IOP).
角膜密度测量测量角膜不透明度,这可能会受到青光眼及其治疗的影响.

研究的目的:

在POAG患者中,在trabeculectomy后12个月内调查Scheimpflug角膜密度度的变化.
为了比较POAG患者手术后的角膜密度与健康对照.
评估降低眼内压力和局部药物使用对角膜透明度的影响.

主要方法:

研究了一组35名POAG患者和34名健康对照组.
用Scheimpflug Pentacam HR角膜拓图来评估特定角膜区域和象限中的角膜密度.
在手术前收集了眼内压力 (IOP) 降低剂的数据,包括化 (BAC) 含量.

主要成果:

轨道切除术导致平均内血压和使用的内血压降低剂的数量显著下降 (p < 0.001).
在大多数角膜区域和象限中,角膜密度计值在手术后12个月显著下降.
在手术后的POAG患者和对照组之间没有观察到角膜密度测量的显著差异.

结论:

停止局部抗葡萄糖性药物,特别是含有化 (BAC) 的药物,可能会提高角膜的透明度.
在轨膜切除术后有效降低IOP似乎可以改善角膜不透明度.

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...

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...
