概括
内注射抗VEGF药物可以导致眼内压力 (IOP) 暂时升. 与aflibercept相比,法里西马布的初始内血压升高较低,所有内血压水平在15分钟内正常化.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜疾病 视网膜疾病
- 药理学 药理学是指药理学的学科.
背景情况:
- 抗血管内皮生长因子 (VEGF) 药物的静脉内注射 (IVT) 是视网膜疾病的标准.
- IVT可能导致眼内压力 (IOP) 升高.
研究的目的:
- 为了比较短时间的注射后的内血压变化,在aflibercept 8 mg和faricimab和aflibercept 2 mg后.
- 评估不同抗VEGF药物的安全性和有效性,以管理注射后的IOP.
主要方法:
- 一项观察性前性研究,涉及90名患有AMD或DME的患者.
- 患者接受了aflibercept 2 mg,aflibercept 8 mg,或法里西马布通过IVT.
- 在注射前和注射后30秒,5分钟和15分钟,使用iCare IC200度计测量了内压.
主要成果:
- 所有组都在注射后30秒内显著增加了内压.
- 与aflibercept 2 mg (41.47±12.95 mm Hg) 和aflibercept 8 mg (43.46±8.97 mm Hg) 相比,法里西马布的初始平均内血压增加率较低 (32.19±11.06 mm Hg).
- 在注射后15分钟,所有组的内脏压力都恢复到正常限度,在后来的时间点上,药物之间没有统计学上显著的差异.
结论:
- 在aflibercept和faricimab的IVT后发生过渡性IOP尖峰,类似于aflibercept 2 mg.
- 观察到的内血压升高是暂时的,注射后15分钟内正常化.
- 虽然法里西马布的初始IOP峰值较低,但在研究的抗VEGF药物中,整体IOP概况是可比的.

Open Angle Glaucoma: Treatment
393
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
438
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
508
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...
