概括
气泡覆盖Descemet膜内皮皮质角质成形 (DMEK) 移植的气泡覆盖在仰卧位置 (0°) 最高. 在手术后的前48小时,最佳定位至关重要,以防止移植物脱落.
科学领域:
- 眼科医生 眼科 眼科
- 角膜外科手术 角膜外科手术
- 植入物附加部位的附加部位
背景情况:
- 德塞米特膜内皮皮质角膜整形术 (DMEK) 依赖于气泡坦波纳德进行移植粘附.
- 了解DMEK后的气泡行为对于成功的移植集成至关重要.
研究的目的:
- 在DMEK后分析气泡大小和移植覆盖在各种视角.
- 为了确定DMEK后移植粘附的最佳患者定位.
主要方法:
- 对465种DMEK手术进行观察性前性研究.
- 从0°到105°的视角进行手术内和每日术后泡移植覆盖范围的分析.
- 使用了20%的硫六化物 (SF) 气空气混合物用于眼内吸管.
主要成果:
- 在0° (仰卧) 视角上始终观察到最大的移植覆盖面.
- 在DMEK后的前48小时内,超过85%的平均移植覆盖率保持在0°-45°视角之间.
- 移植覆盖率在72小时后下降,视角为0°,在96小时内保持了>85%的覆盖率,与其他角度不同.
结论:

Angle Closure Glaucoma: Treatment
459
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...

Glaucoma: Overview
530
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...
