概括

切换到静脉内勃鲁西祖马布 (IVBr) 治疗新血管与年龄相关的黄斑变性 (nAMD) 显著减少了视网膜和胸膜厚度. 此外,IVBr可能会降低胆道血流,特别是在老年患者中.

科学领域:

眼科医生眼科眼科
视网膜疾病视网膜疾病
血管生物学血管生物学

背景情况:

抗血管内皮生长因子 (VEGF) 治疗是新血管与年龄相关的黄斑变性 (nAMD) 的标准.
维格F抑制剂可能会影响眼睛的血液流动和胸膜厚度,其临床影响尚不清楚.
这项研究调查了在耐火性nAMD中切换到静脉内糖 (IVBr) 后的结果.

研究的目的:

在耐火性nAMD患者中,评估从aflibercept或ranibizumab转换为IVBr的1个月后影响.
为了评估视觉敏度,视网膜厚度,胸膜厚度和胸膜血流的变化.
为了确定胆道血流变化的预测因素.

主要方法:

对50个患有nAMD的眼睛进行前性单中心研究.
在IVBr治疗前和1个月后评估的最佳校正视力敏度 (BCVA),中枢视网膜厚度 (CRT),亚膜胆道厚度 (SFCT) 和胆道血流 (CHOR-MBR).
激光斑点流图用于测量血液流量;进行回归分析以确定CHOR-MBR变化的预测因素.

主要成果:

保持了BCVA;CRT和SFCT显著下降 (P < 0.001).
胸腔层面积和亮面积显著减少;胸腔血管度指数没有变化.
视神经头部和胆道血流 (ONH-MBR和CHOR-MBR) 显著下降 (分别P=0.004和P<0.001).
基线SFCT是CHOR-MBR变化的唯一显著预测因素;年龄较大与较薄的SFCT和更大的CHOR-MBR减少相关.

结论:

静脉内勃鲁西祖马布 (IVBr) 治疗导致在nAMD中视网膜和胸膜厚度显著降低.
IVBr可能会降低冠状腺血流,特别是在老年人和具有较薄的基线亚叶冠状腺厚度的人中.
需要进一步的研究,以了解IVBr对眼睛血液动力学的长期影响.

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment

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...

Glaucoma: Overview

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...
