概括

拉尼比祖马布治疗改善了视网膜中枢静脉封闭 (CRVO) 患者的视觉盘输液,视觉盘血流与视觉敏度的相关性比斑点输液更强. 这表明盘内血管密度 (VD) 可能预测CRVO的视觉结果.

科学领域:

眼科医生眼科眼科
血管生物学血管生物学
医疗成像医学成像

背景情况:

中央视网膜静脉封闭 (CRVO) 与黄斑 (ME) 显著影响视觉功能.
光盘和斑点的微血管变化是CRVO-ME的关键病理特征.
在CRVO患者中经常观察到出血学异常.

研究的目的:

评估拉尼比祖马布对光盘和在肌痛性脑脊髓炎患者的斑点微血管输液的治疗影响.
研究CRVO患者的微血管密度和视力敏度之间的关系.
与健康对照组相比,评估CRVO患者的血液病理参数.

主要方法:

光学连贯断层扫描血管造影 (OCTA) 用于量化光盘和斑点毛细管中的血管密度 (VD).
测量了中央黄斑厚度 (CMT) 和最佳校正视敏度 (BCVA).
每月给人静脉内注射拉尼比祖马布,持续3个月,进行治疗前后的评估.

主要成果:

拉尼比祖马布治疗显著增加了视觉盘VD (全盘,盘内,周周) 和减少了CMT.
黄斑表面和深层毛细管VD治疗后显示非显著的减少.
基线BCVA与光盘VD相关,光盘内VD显示最强的关联;BCVA改善与光盘VD治疗后积极相关.

结论:

光盘输液,特别是光盘内静脉输液,是视敏度的更强的预测因素,而不是CRVO中的斑点输液.
拉尼比祖马布有效地改善光盘 perfusion,但可能对黄斑 perfusion 有限或有害影响.
在CRVO患者中观察到血学参数升高,C/D比率降低可能是敏感性因素.

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...
