概括
刚性角膜隐形眼镜 (RCCL) 配备了顶端清除,在12个月内没有改变角膜 (KC) 的进展. 短暂的断药期可能无法完全逆转角膜变化,影响测量.
科学领域:
- 眼科医生 眼科 眼科
- 角膜疾病 角膜疾病
- 视光学测量 视光学测量 视光学测量
背景情况:
- 角膜 (KC) 是一种渐进的角膜脱膜症.
- 刚性角膜隐形眼镜 (RCCL) 用于管理KC.
- 顶端隙合是RCCL应用的一种方法.
研究的目的:
- 评估峰清除RCCL合对KC进展的12个月影响.
- 为了比较治疗眼睛和未治疗眼睛的KC进展.
主要方法:
- 对237个KC眼睛进行了回顾性,受控的纵向研究.
- 31个未经治疗的眼睛和31个接受RCCL治疗的眼睛的倾向性得分匹配.
- 评估最佳校正视敏度 (BCVA),角膜断层扫描和异常.
- 通过角质量计,厚度或BCVA变化定义的KC进展.
主要成果:
- 两组之间没有BCVA,断层扫描或异常的显著差异.
- 可比的KC进展率:12.9%未经治疗的眼睛与19.35%RCCL治疗的眼睛在12个月.
- 在RCCL组中,在3个月后,前侧角质量测量 (K2) 的显著减少.
结论:
- 在12个月内,RCCL安装并没有显著改变KC整体进展.
- 3个月的K2减少表明,透镜佩戴后角膜正常化时间不足.
- 为了准确的KC评估,需要进一步研究最佳的透镜停止.

Angle Closure Glaucoma: Treatment
1.2K
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
963
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.

Glaucoma: Overview
1.3K
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...
