概括
结合角膜交叉链接 (CXL) 与地形导向光折射性角膜切除术 (TG-PRK) 来治疗角膜会导致比单独使用CXL更显著和持久的角膜雾. 雾会改善,但在联合手术后会持续更长时间.
科学领域:
- 眼科医生 眼科 眼科
- 角膜外科手术 角膜外科手术
- 生物医学光学 生物医学光学
背景情况:
- 角膜是一种渐进的角膜脱落.
- 角膜交叉链接 (CXL) 是一种标准的治疗方法,以阻止进展.
- 地形导向光折射性角膜切除术 (TG-PRK) 可以调整角膜表面.
研究的目的:
- 为了比较角膜雾的发展后加速角膜交叉链接 (CXL) 单独与同时CXL和地形导向光折射性角膜切除术 (TG-PRK) 在角膜患者.
- 评估联合手术对角膜密度计的影响.
主要方法:
- 对106只眼睛进行了回顾性病例控制研究.
- 单独加速CXL (CXL组) 和联合CXL + TG-PRK (TG-PRK组) 的比较.
- 角膜密度测量在手术前,3个月后,1年后使用 Scheimpflug 装置进行手术后测量.
主要成果:
- 与CXL组相比,TG-PRK组在3个月和1年内显示出明显更高的角膜密度计 (雾) (P < 0.001).
- 雾在1年内在很大程度上恢复到基线,除了TG-PRK组的中央2毫米前角膜外.
- 较大的角膜平与组合组中更多的雾相关,但雾与视力敏度变化无关.
结论:
- 同时的TG-PRK和CXL导致更明显和持久的角膜比单独的CXL.
- 角膜雾随着时间的推移而改善,但在联合手术后,它会持续更长时间.
- 角膜密度计是监测雾和指导患者管理的有用工具.

Angle Closure Glaucoma: Treatment
413
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
375
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
484
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...
