概括
与较大的BOZD相比,带有5毫米背光区直径 (BOZD) 的正视科 (ortho-k) 在儿童中显示出优异的近视控制. 这表明一种与较大的相对外围折射 (RPR) 转移相关的机制.
科学领域:
- 眼科医生 眼科 眼科
- 控制近视 控制近视
- ортокератология ортокератология是一个专业的专业.
背景情况:
- 脊椎病理学 (ortho-k) 是一种使用专用隐形眼镜的近视控制方法.
- орто-k镜片的后光区直径 (BOZD) 可能会影响治疗的有效性.
- 了解该机制,包括相对外围折射 (RPR) 变化,对于优化近视控制至关重要.
研究的目的:
- 为了评估1年的疗效与不同的BOZDs (5毫米,5.5毫米,6毫米) 的ortho-k对儿童近视控制.
- 调查潜在的作用机制,重点关注RPR和更高阶异常 (HOA).
- 评估与不同ortho-k BOZDs相关的安全性和视觉质量结果.
主要方法:
- 一项随机临床研究,涉及62名儿童,分为三个ortho-k组 (5毫米,5.5毫米,6毫米BOZD).
- 在1年内收集的数据包括轴长 (AL),RPR (通过多光谱折射拓测量),对比度 (CS) 和角膜HOA.
- 统计分析包括单向ANOVA和Pearson的相关性,以比较组和评估参数之间的关系.
主要成果:
- 5毫米BOZD组在1年后 (P=0.001) 与6毫米BOZD组 (0.18±0.11毫米) 相比,显著减少了轴向延伸 (0.07±0.09毫米).
- 与6毫米BOZD组相比,5毫米BOZD组在多个区域 (总,,鼻和外围) 呈现出更多近视RPR.
- 轴延长与总RPR的增加正相关 (r=0.756,P<0.001);在5毫米BOZD组中,CS下降和角膜HOA增加.
结论:
- 带有5毫米BOZD的正视科在控制1年内儿童近视进展方面更有效.
- 增强的近视控制效应可能归因于相对外周折射中较大的近视转移.
- 需要进一步研究不同ortho-k BOZD的光学机制和长期影响.

Open Angle Glaucoma: Treatment
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.

Angle Closure Glaucoma: Treatment
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...
