概括

皮质脱角膜交叉链接 (CXL) 对进展性角质 (KCN) 患者是安全的,没有显示干眼症状恶化. 然而,CXL在手术后六个月没有显著改善角膜地形或光学偏差.

科学领域:

眼科医生眼科眼科
角膜外科手术角膜外科手术
视觉科学视觉科学视觉科学

背景情况:

渐进性角质 (KCN) 经常呈现眼表面功能障碍,包括干眼.
皮质脱角膜交叉链接 (CXL) 是一种用于阻止KCN进展的标准治疗方法.

研究的目的:

评估表皮脱离CXL对眼睛表面参数和逐渐KCN中的角膜拓学的影响.
为了评估KCN的CXL后光学参数的变化和更高阶偏差.

主要方法:

一项前性,单臂干预性研究,涉及25名KCN患者的30只眼睛,接受了CXL的上皮脱落.
眼睛表面参数 (TBUT,Schirmer I,OSDI) 和角膜地形/偏差 (Pentacam) 在基线和CXL后6个月被测量.

主要成果:

表皮脱离CXL并没有显著改变6个月的撕裂分解时间,希尔默测试结果或OSDI得分.
在CXL后观察到K1和K2值的显著下降以及表面方差指数 (ISV) 的改善.
视角最佳校正视敏度 (BCVA) 和更高阶异常在手术后6个月保持不变.

结论:

表皮脱离CXL对于进展性KCN患者是安全的,不会加剧现有的眼睛表面问题,如干眼.
虽然CXL可以稳定KCN,但它可能不会在六个月内导致角膜地形指数或光学偏差的显著改善.

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...
