概括

在患有创伤后角膜创伤的患者中,以拓指导的定制切除治疗 (TCAT) 有效地调整了角膜表面,并减少了更高层次的异常. 这种治疗改善了未经纠正和最佳纠正的视力敏度,为角膜形症提供了有益的第二阶段选择.

科学领域:

眼科眼科
角膜外科手术
折射手术

背景情况:

创伤后的角膜伤口需要 sutures是常见的,导致透明度降低,角膜扭曲,纹和更高层次的异常 (HOA).
在角膜创伤后,除激光治疗是治疗视觉缺陷的潜在干预措施.

研究的目的:

评估以地形为导向的定制切除治疗 (TCAT) 作为角膜损伤的第二阶段干预的有效性.
评估TCAT对角膜表面规律性,白和创伤后更高层次的偏差的影响.

主要方法:

在初始伤口稳定后接受TCAT治疗的四名患者 (三名有穿透性,一名有形角膜创伤) 的队列研究.
进行了TCAT,用于预防雾,随后测量了未经校正的远距离视力敏度 (UDVA),最佳校正的远距离视力敏度 (BCVA),折射性白,地形白和更高阶偏差 (RMS).
在治疗后对角膜愈合和折射变化进行了监测.

主要成果:

在所有患者中,TCAT成功调整了角膜表面并减少了HOA.
在Snellen图表上观察到UDVA的显著改善,范围为3至7. 5行.
结果的UDVA在0. 7至1.2之间,BCVA在1. 0至1.5之间,表明视力恢复很大.

结论:

在患有创伤后角膜形症的患者中,TCAT有效调节角膜表面并减少HOA.
在角膜创伤后,TCAT是一种潜在的有益的第二阶段治疗选择,可以改善视觉结果.

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...

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...
