概括
湿时与年龄相关的黄斑变性 (AMD) 的治疗和延长 (T&E) 方法显示了视觉收益,但不低于固定双月一次aflibercept注射,并且在第一年没有降低治疗负担.
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:
- 与年龄相关的黄斑变性 (AMD) 治疗,如定期的视内注射,造成了严重的医疗负担.
- 开发具有成本效益和高效的治疗方案对于管理湿 AMD至关重要.
研究的目的:
- 为了比较每两个月固定剂量的aflibercept注射与湿 AMD 的治疗和延长 (T&E) 方法的疗效.
- 在不同的aflibercept治疗策略中评估视力敏度,解剖结果,治疗间隔和不良事件.
主要方法:
- 一年随机,开放标签,前性试验,涉及44名以前没有接受过治疗的湿 AMD 患者.
- 患者最初接受了aflibercept注射,然后随机分配到每两个月固定剂量或T&E,以算法为基础的间隔调整.
- 评估的结果包括最佳校正视力敏度 (BCVA),解剖学变化,注射频率和安全性.
主要成果:
- 双月固定剂量 (5.0个字母) 和T&E (4.1个字母) 都改善了BCVA,尽管T&E没有满足非劣势性标准 (p=0.096).
- 平均而言,T&E患者接受的注射量 (9.6) 超过固定剂量组 (7.7) (p < 0.001).
- 在两个治疗手臂之间观察到可比的解剖结果.
结论:
- T&E方法在湿湿的AMD中显示出视觉益处,但在统计学上并不低于每两个月固定剂量.
- 在治疗的第一年内,T&E策略没有减少治疗负担.
- 需要进一步的研究来优化T&E算法用于AMD中的aflibercept治疗.

01:27Open Angle Glaucoma: Treatment
938
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.

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...
