概括
用组织等离子素激活剂 (tPA) 进行的Pars plana玻璃切除术改善了因创伤引起的亚黄斑出血 (SMH) 的视力. 这种手术方法在闭合球损伤患者中显示出视觉上的好处.
科学领域:
- 眼科 眼科
- 视网膜手术
- 创伤护理
背景情况:
- 闭球创伤中的黄斑下出血 (SMH) 可能导致显著的视力丧失.
- 目前对创伤引起的SMH的治疗选择有限.
- 早期干预对于视力恢复至关重要.
研究的目的:
- 评估帕斯普拉纳玻璃切除术 (PPV) 与组织等离子素激活剂 (tPA) 诱导的凝块溶解和气动移位的视觉结果.
- 评估这种手术技术在受闭眼外伤的患者中的有效性.
- 确定手术前的视力敏度或手术时间是否会影响结果.
主要方法:
- 7个患者的7个眼睛的回顾性多中心干预病例系列.
- 所有患者都接受了PPV,并对SMH因闭球损伤而受到皮tPA的治疗.
- 主要结果是Snellen视觉敏度的变化;在所有情况下使用气体吸管 (SF6或C3F8).
主要成果:
- 平均随访时间为4. 6个月.
- 平均最佳校正视力 (BCVA) 从20/1020提高到20/114 (P=0. 025).
- 手术前的BCVA和手术时间 (14天内或之后) 并不是最终BCVA的显著预测因素.
结论:
- 通过tPA介导的凝块溶解和气动位移进行的手术可能为创伤引起的SMH提供视觉益处.
- 这种技术在没有视网膜血管疾病的患者中显得有效.
- 需要进行更大规模的前性研究来证实这些发现,并制定最终的治疗指南.

01:28Angle Closure Glaucoma: Treatment
669
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...

01:27Open Angle Glaucoma: Treatment
557
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.
