- 血管生物学 血管生物学
背景情况:
- 主要视角闭合光眼 (PACG) 是视力丧失的重要原因之一.
- 虹膜/视角的新血管化 (NVI/NVA) 通常与严重的视网膜病理有关.
- 在没有明显的视网膜疾病的情况下,PACG中NVI/NVA的发生并不常见.
研究的目的:
- 描述PACG呈现NVI/NVA.的临床病例.
- 调查PACG中NVI/NVA潜在的潜在机制和临床意义.
- 为了区分这种表现与新血管性玻璃眼 (NVG) 的其他原因.
主要方法:
- 三名被诊断患有PACG和NVI/NVA的患者的详细病例描述.
- 综合眼科检查,包括裂纹灯,阴影镜和 fundus光素血管学 (FFA).
- 系统性评估包括 Carotid Doppler 和凝血概况;排除 NVI / NVA 的二次原因.
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...

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...

Open Angle Glaucoma: Treatment
951
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.
