概括
激光能量对一次性选择性激光形术 (SLT) 镜片的损伤降低了治疗的有效性. 较大的透镜损伤与绿眼病患者的眼内压力降低较小相关. 建议重新考虑使用一次性SLT镜头.
科学领域:
- 眼科医生 眼科 眼科
- 青光眼的治疗方法 青光眼治疗方法
- 激光疗法是一种激光疗法.
背景情况:
- 一次性选择性激光脊椎造形 (SLT) 镜头在使用过程中可能会受到损伤.
- 这种损害可能会影响SLT手术的治疗效果.
- 了解影响透镜损伤及其后果的因素对于优化青光眼治疗至关重要.
研究的目的:
- 确定与一次性SLT镜头损坏程度相关的因素.
- 为了确定透镜损伤对患者治疗结果的影响,特别是眼内压力 (IOP) 降低.
- 为了评估激光能量参数和镜头损坏之间的关系.
主要方法:
- 分析了2020-2021年间接受SLT的82名患者的113只眼睛.
- 记录患者的基线特征,手术设置,医生年龄和透镜损伤区域.
- 计算治疗反应作为手术前和手术后IOP之间的差异.
主要成果:
- 镜片损伤面积与总激光能量 (r=0.34) 和每次应用的平均能量 (r=0.37) 有正相关.
- 增加的透镜损伤与IOP降低的减少有关 (r=-0.19).
- 镜片损伤与患者的青光眼严重程度指标或用户设置无关;更高的手术前IOP和更小的杯对盘比率预测了更大的IOP减少.
结论:
- 更高的激光能量有助于一次性SLT镜头损坏.
- 显著的透镜损伤与SLT降低内膜压力的效率降低有关.
- 研究结果表明,需要重新评估在临床实践中一次性SLT镜片的常规使用.

Angle Closure Glaucoma: Treatment
508
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...

Open Angle Glaucoma: Treatment
453
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.
