概括
伪皮性玻璃眼 (XFG) 中水性幽默内甲蛋白-1 (ET-1) 的升高与视网膜微血管变化相关,与血ET-1不同. 这表明眼内ET-1在XFG病变发生过程中起着关键作用.

背景情况:
- 玻璃眼,不可逆转的失明的主要原因,涉及光神经损伤往往与血管调节障碍相关.
- 内衣素-1 (ET-1) 是一种强大的血管收缩剂,涉及各种血管病理,包括可能在青光眼中发挥作用.
- 伪皮性玻璃眼 (XFG) 和初级开角玻璃眼 (POAG) 是不同的玻璃眼形式,具有不同的潜在机制.
研究的目的:
- 调查血和水性幽默 (AH) 内甲素-1 (ET-1) 水平和视网膜微血管参数之间的关联.
- 为了比较这些水平和参数,在患有伪除性玻璃眼 (XFG) 和初级开角玻璃眼 (POAG) 的患者和对照对象.
- 确定眼内与全身ET-1在XFG和POAG的致病性中的特定作用.
主要方法:
- 酶相关免疫吸收试验 (ELISA) 用于测量血和水性幽默 (AH) ET-1水平.
- 光学连贯断层扫描血管学 (OCT-A) 用于评估光盘和斑点中的微血管参数.
- 研究包括23名XFG患者,20名POAG患者和34名对照患者.
主要成果:
- 与POAG和对照组相比,XFG组的水性幽默 (AH) ET-1水平显著更高.
- 在XFG患者中,升高的AH ET-1水平与表面和辐射周毛细血管血管密度 (SCP VD和RPC VD) 有显著的负相关性.

Open Angle Glaucoma: Treatment
591
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
789
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
708
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...
