概括
用胺合的伊--石榴激光背囊切除术暂时增加角膜厚度,前腔深度和镜头. 眼内透镜倾斜在手术后保持稳定.
科学领域:
- 眼科医生 眼科 眼科
- 激光手术 激光手术是一种激光手术.
- 前段成像前段成像的使用
背景情况:
- 使用合--石榴石 (Nd:YAG) 激光器进行后部囊切除术是治疗后部囊变暗的常见手术.
- 了解Nd:YAG囊切除术对前段参数的即时和短期影响,对于患者管理和IOL稳定性评估至关重要.
研究的目的:
- 为了在Nd:YAG激光后背囊切除术后前部段参数的前性评估变化.
- 为了比较Nd:YAG囊切除术对前段参数的影响,基于眼内透镜 (IOL) 类型 (C环与板).
主要方法:
- 一项前性研究,涉及接受Nd:YAG激光后囊切除术的患者.
- 前段参数包括中角膜厚度,前腔深度,透镜和瞳孔直径使用扫描源光学连贯断层扫描来测量.
- 眼内透镜倾斜的评估是使用光路差异扫描III进行的,在手术前和手术后30分钟,1周和1个月进行测量.
主要成果:
- 在囊切除术后30分钟观察到中角膜厚度,前腔深度和透镜的显著暂时增加,在1周后恢复到基线.
- 虽然板式IOL显示了前腔深度和镜头顶在30分钟后比C-循环类型更大增长的趋势,但这些差异在统计学上并不显著.
- 在 Nd:YAG 囊切除术后,在 IOL 组中都没有检测到眼内透镜倾斜的显著变化.
结论:
- Nd:YAG激光后部囊切除术诱导中枢角膜厚度,前腔深度和透镜的短暂变化.
- 该程序不会导致眼内透镜倾斜的显著变化,这表明无论眼内透镜类型如何,眼内透镜的定位都是稳定的.

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...

Open Angle Glaucoma: Treatment
951
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.
