概括

带有较小背光区直径 (BOZD) 的正视镜 (ortho-k) 镜片导致两岁以上儿童的治疗区域 (TZ) 较小,轴延伸 (AE) 较少. 这些发现表明,BOZD影响了近视控制有效性.

科学领域:

眼科医生眼科眼科
视光学测量视光学测量视光学测量
儿科眼科护理儿科眼科护理

背景情况:

脊椎病理学 (ortho-k) 是一种近视控制方法,使用一夜穿戴的刚性气体透透镜.
镜头设计参数,如后光区直径 (BOZD),可能会影响治疗结果.
了解这些参数对于优化儿童近视管理策略至关重要.

研究的目的:

为了比较两个年来穿着6mm或5mmBOZD正方形眼镜的儿童的轴延长 (AE) 和治疗区 (TZ) 特性.
为了研究透镜设计和近视控制治疗期间眼睛变化之间的关系.

主要方法:

一项随机研究涉及45名近视儿童 (6至11岁以下) 来自中国族裔.
参与者被分配使用6毫米或5毫米BOZD ortho-k镜头.
关于轴延长,治疗区域直径和胸膜厚度的数据在基线和每六个月收集一次,持续两年.

主要成果:

与6mm BOZD镜头 (水平:3.84mm,垂直:3.42mm) 相比,具有5mm BOZD的镜头产生了明显较小的TZ直径 (水平:2.69mm,垂直:2.65mm).
穿着5毫米BOZD镜头的受试者在24个月后,与穿着6毫米BOZD镜头 (0.35毫米) 的受试者相比,轴延长 (0.15毫米) 显著减少.
胸膜厚度的变化是暂时的,与AE的关联非常弱,这表明其他因素对减少AE的影响更大.

结论:

较小的BOZD ortho-k镜头导致较小的TZ直径,并且与两岁以上儿童的轴延伸减少有关.
这些发现表明,BOZD是对ortho-k治疗近视控制有效性的关键因素.
冠状腺厚度的变化似乎在观察到的轴延长减少中起到最小的作用.

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment

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...
