概括
小切口镜片提取 (SMILE) 显示了对纹症的轴依赖结果. 违反规则和斜视的眼睛实现了可预测的校正,而符合规则的眼睛经历了不足的校正.
科学领域:
- 眼科医生 眼科 眼科
- 折射手术是一种折射手术.
- 角膜外科手术 角膜外科手术
背景情况:
- 在折射手术中,眼际形轴异调带来了独特的挑战.
- 了解轴依赖结果对于优化患者结果至关重要.
- 小切口镜片提取 (SMILE) 是一种广泛使用的折射手术.
研究的目的:
- 评估SMILE的视觉和折射结果,基于在患有整眼不一致症的患者中的形轴.
- 分析SMILE的轴特定有效性和可预测性.
- 为了比较符合规则的眼睛 (WTR),违反规则的眼睛 (ATR) 和斜视的眼睛 (OA) 的结果.
主要方法:
- 75名患有整眼标轴异调的患者被分为WTR/ATR,WTR/OA和ATR/OA队列.
- 折射结果,角膜地形和波浪偏差在手术前和手术后 (1个月和6个月) 被评估.
- 使用Alpins方法的矢量分析被用来评估形纠正的准确性.
主要成果:
- 6个月后,在轴之间没有发现视力敏度或残余折射误差的显著差异.
- 与WTR眼睛 (47%和38%) 相比,ATR (84%) 和OA (64%) 的更高百分比,眼睛达到≤0.25 D的残留白症 (47%和38%).
- SMILE在WTR眼中显示有系统的低校正 (CI <1.0),但在ATR和OA眼中显示完全的校正. 与相反的眼睛相比,ATR眼睛的误差角度更大,OA眼睛显示Trefoil30°偏差减少.
结论:
- 微笑证明了轴特定的疗效,在ATR和OA眼中具有可预测的结果.
- 接受微笑的WTR眼睛,以纠正阿斯蒂格玛特症,容易受到不足的纠正.
- 在手术前对形轴的评估对于管理接受SMILE的整眼失调患者至关重要.

Angle Closure Glaucoma: Treatment
1.2K
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
963
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.
