- 医疗成像医学成像
背景情况:
- 大于400微米的异形斑点孔 (IMH) 构成治疗挑战.
- 目前的分级系统缺乏对形态和微观结构特征的综合.
- 需要一个新的关闭分级系统,用于大IMHs与ILM剥离的体外切除术后.
研究的目的:
- 为大型IMH提出一个新的关闭分级系统.
- 为了评估系统与视力敏度的相关性.
- 确定影响关闭等级的术前风险因素.
主要方法:
- 从64名IMH大 (>400微米) 的患者对68只眼睛进行了回顾性审查.
- 术前数据和光谱域光学连贯性断层扫描 (SD-OCT) 的分析.
- 术后评估SD-OCT特征和最佳校正视敏度 (BCVA) 在1,4和10个月.
主要成果:

Glaucoma: Overview
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...
Open Angle Glaucoma: Treatment
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.

Angle Closure Glaucoma: Treatment
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...
