Open Angle Glaucoma: Treatment

953
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

1.1K
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...

概括

糖尿病黄斑的静脉内膜拉尼比祖马布治疗显著减少了视网膜中枢静脉等效 (CRVE) 和增加了动脉与静脉的比率 (AVR). 这表明,拉尼比祖马布可以通过改变视网膜血管口径来改善视力.

科学领域:

  • 眼科医生 眼科 眼科
  • 医疗视网膜 医学视网膜
  • 血管生物学 血管生物学

背景情况:

  • 糖尿病黄斑 (DMO) 是糖尿病患者视力丧失的主要原因.
  • 静脉内拉尼比祖马布是DMO的常见治疗方法,但其对视网膜血管口径的影响尚未完全理解.

研究的目的:

  • 评估内拉尼比祖马布对DMO患者视网膜血管口径的影响.
  • 为了将血管口径的变化与视觉敏度和黄斑厚度相关联.

主要方法:

  • 一项前性研究的后期分析,涉及76只眼睛的67名未经治疗的DMO患者.
  • 患者每月接受三次拉尼比祖马布注射,随后进行前期注射 (PRN).
  • 视网膜血管口径使用数字底部照片和半自动化程序 (SIVA) 测量,计算中央视网膜动脉等价值 (CRAE),中央视网膜静脉等价值 (CRVE) 和动脉与静脉比率 (AVR).

主要成果:

  • 拉尼比祖马布治疗导致2个月和12个月的CRVE显著减少 (分别P < 0.0001和P = 0.03).
  • 在2个月和12个月,AVR显著增加 (分别P = 0.02和P = 0.01).
  • 最好的校正视敏度 (BCVA) 显著改善,中央黄斑厚度 (CMT) 从基线显著减少到12个月 (P <0.001两者).

结论:

  • 在DMO患者中,内拉尼比祖马布治疗与CRVE显著下降和AVR增加有关.
  • 这些血管口径变化可能有助于观察到的BCVA和CMT的改善,可能是通过降低视网膜静脉水静压.
