- 防止GDD管侵蚀对于长期的设备功能和患者的结果至关重要.
- 用各种补丁材料来保护GDD管免受侵蚀.
研究的目的:
- 为了比较异性护膜层和角膜 stromal 补丁之间管道侵蚀的发生率.
- 评估侵蚀率,特别是在涉及艾哈迈德玻璃眼植入物 (AGI) 和保罗玻璃眼植入物 (PGI) 的手术中.
主要方法:
- 一项回顾性研究包括了84名接受GDD手术的患者.
- 患者接受了带膜层 (n=43) 或角膜层 (n=41) 的贴片来覆盖GDD管.
- 在18个月的随访期间,对管道侵蚀进行了监测.
主要成果:

Glaucoma: Overview
771
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
691
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
577
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.
