概括
标准角膜交叉连接 (S-CXL) 和加速角膜交叉连接 (A-CXL) 均有效地在8年内阻止了角膜的进展. 加速方案证明了非劣势性,在管理这种渐进的眼睛疾病方面显示了可比的长期疗效.
科学领域:
- 眼科医生 眼科 眼科
- 角膜外科手术 角膜外科手术
- 视觉科学科学 视觉科学
背景情况:
- 渐进性角质 (KC) 对视力构成重大威胁.
- 角膜交叉连接 (CXL) 旨在通过加强角膜组织来阻止KC的进展.
- 评估不同CXL协议的长期结果对于临床实践至关重要.
研究的目的:
- 为了比较标准角膜交叉连接 (S-CXL) 与加速角膜交叉连接 (A-CXL) 的8年疗效,在KC进展的患者中.
- 评估S-CXL和A-CXL对视敏度和角膜参数的长期影响.
主要方法:
- 对61只眼睛进行了回顾性队列研究,这些眼睛患有进展性KC.
- 患者接受了S-CXL (N=16) 或A-CXL (N=45).
- Corneal 断层扫描,高阶异常 (HOA) 和视觉敏度在 8 年内使用 Scheimpflug 影像和混合效应模型进行了分析.
主要成果:
- S-CXL和A-CXL都显著减少了前角膜曲率和最薄的角膜厚度,长达8年.
- 在两组中,HOA昏迷下降,而视力敏度仅在96个月的S-CXL组中显示出边缘显著改善.
- Corneal 光学密度最初增加,然后正常化; 复杂率在协议之间是相似的.
结论:
- 无论是S-CXL还是A-CXL,都能在8年内成功地长期阻止KC的进展.
- 加速协议 (A-CXL) 在治疗角方面与标准协议 (S-CXL) 不逊色.

01:28Angle Closure Glaucoma: Treatment
1.1K
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...

01:27Open Angle Glaucoma: Treatment
917
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.
