概括
将降低流量光动疗法 (RF-PDT) 添加到静脉内阿弗利塞普注射 (IAI) 并没有改善多性胆道血管病变 (PCV) 的视力敏度,但显示出更高的多性损伤关闭率. 需要进一步的研究.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜疾病 视网膜疾病
- 血管眼部疾病 血管眼部疾病
背景情况:
- 聚冠状血管病变 (PCV) 是视力丧失的重要原因之一.
- 内阿弗利塞普特注射 (IAI) 是PCV的标准治疗方法.
- 减少流量光动疗法 (RF-PDT) 与PCV的IAI结合的作用尚未得到充分证实.
研究的目的:
- 为了比较组合治疗 (RF-PDT + IAI) 与PCV患者的IAI单一治疗的疗效.
- 评估功能性 (视觉敏) 和解剖学 (损伤关闭) 的结果.
主要方法:
- 一个双面罩,假控制,随机临床试验 (NCT03941587) 涉及50岁以上的症状斑点PCV的患者.
- 参与者被随机分配1:1接受RF-PDT + IAI或假PDT + IAI.
- 主要结局是52周最佳校正视敏度 (BCVA) 的变化;次要结局包括12周的多角性损伤 (PL) 关闭.
主要成果:
- 在160名计划参与者中,只有60人被录取.
- 在52周,组合手臂 (12.7个字母) 和单一治疗手臂 (11.9个字母) 之间的平均BCVA增益没有显著差异.
- 在12周,PL关闭率在组合手臂 (66.7%) 与单一治疗手臂 (33.3%) 相比显著更高.
结论:
- 由于样本规模有限,该研究无法证明组合疗法在视力敏度方面比IAI单一疗法更优越或不劣.
- 在12周的组合治疗中观察到较高的PL闭合率是次要发现,需要进一步调查.
- 这些二次发现被认为是产生假设的,并且在临床上与本试验的功能结果无关.

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.

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...
