概括
慢性角膜可以在内皮角质整形术 (EK) 后导致严重的角膜平整,导致高视度折射结果. 医生应考虑EK前胀的持续时间,并考虑对密集胀的早期干预.
科学领域:
- 眼科医生 眼科 眼科
- 角膜外科手术 角膜外科手术
- 折射手术是一种折射手术.
背景情况:
- 慢性角膜可以导致角膜的显著结构变化.
- 内皮角膜整形 (EK) 是一种常见的角膜的手术程序.
- 慢性胀对EK后角膜生物力学的长期影响尚未完全理解.
研究的目的:
- 介绍一个病例系列的患者经历了无事件的内皮角质整形术 (EK) 后的极端角膜平.
- 描述一个潜在的并发症称为原紧缩综合征后EK在以前的慢性角膜胀的背景下.
主要方法:
- 四名患者 (平均年龄64.8岁) 的病例系列,在经历了4-7.5个月的慢性角膜胀后成功接受了EK.
- 三名患者接受了Descemet膜内皮皮质角质整形 (DMEK) 术,因为Fuchs变症的Descemet仅剥离 (DSO) 失败.
- 一名患者在伪发型角膜病变后接受了Descemet自动化内皮角膜整形 (DAEK).
主要成果:
- 这四名患者在EK后都出现了显著的角膜平.
- 这种平坦化导致了大量的超视光折射转移.
- 由于折射变化和视觉冲击,最佳校正视力敏度在20/40至20/200之间.
结论:
- 长时间的手术前角膜可能使患者在EK后倾向于严重角膜平.
- 在EK之前肌层的持续时间可能会影响外科手术的结果.
- 建议考虑EK手术的时间和用于密集的早期救援治疗 (8周).

01:28Angle Closure Glaucoma: Treatment
438
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...

01:25Glaucoma: Overview
508
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...
