概括
在Descemet之后,眼会经历更多的角膜失补偿.
科学领域:
- 眼科医生 眼科 眼科
- 角膜外科手术 角膜外科手术
- 组织病理学 组织病理学
背景情况:
- 角膜失补偿在角质中比Descemet膜 (DM) 撕裂后的初级先天性玻璃眼 (PCG) 更频繁.
- 了解后角膜形态差异对于解释这种差异至关重要.
研究的目的:
- 为了比较DM的形态和前Descemet的层 (PDL) 在DM断裂的角和PCG眼睛之间的区域.
- 为了将这些形态差异与角膜脱补偿的临床结果相关联.
主要方法:
- 使用前段光学连贯性断层扫描 (AS-OCT) 进行横截面比较研究.
- 从角膜和PCG病例中获得的角膜的组织病理学分析.
- 与健康的对照眼睛进行比较.
主要成果:
- AS-OCT在PCG (80微米) 和眼 (36微米) 中发现了一个更厚的DM-PDL复合体.
- 脱离的DM-PDL高度和长度在角质中显著更大.
- 组织病理学证实PCG中DM较厚 (63.4μm),与角质 (33.2μm) 和对照组 (27.1μm) 相比.
结论:
- 在PCG眼睛中较厚的DM/PDL可能有助于更好的愈合和更少的脱补偿.
- 在角质中较大的DM/PDL脱落,加上较薄的DM,可能会导致DM撕裂后角膜失补偿更频繁.

Glaucoma: Overview
573
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...

Angle Closure Glaucoma: Treatment
500
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
452
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.
