- 眼科医生 眼科 眼科
- 生物医学工程 生物医学工程
背景情况:
- 白内障手术是恢复视力的常见手术.
- 眼内透镜 (IOL) 植入对于视觉结果至关重要.
- IOL倾斜和分散可能会影响视觉表现.
研究的目的:
- 评估内视镜倾斜和分散对视敏度的临床影响.
- 为了研究囊直径特征与内腔眼镜对齐之间的关系.
主要方法:
- 在接受克莱伦CNA0T0内膜眼镜后白内障手术的患者的前性研究.
- 评估最佳距离校正视敏度 (BDCVA) 和距离校正中间视敏度 (DCIVA).
- 使用前方扫描源光学连贯性断层扫描 (OCT) 进行IOL倾斜和分散测量.
主要成果:

Angle Closure Glaucoma: Treatment
1.1K
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
958
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
1.2K
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...
