概括

四种下方斜体削弱程序有效地减少了excyclotorsion. 与其他方法相比,前腔和鼻腔转移 (ANT) 显示了眼睛扭曲的最显著减少.

科学领域:

眼科医生眼科眼科
眼手术整形外科
眼睛的运动性眼睛的运动性

背景情况:

较低斜过度运动 (IOOA) 可以导致显著的V图案视和眼睛扭曲.
削弱下斜肌的削弱程序对于管理IOOA至关重要.
了解不同减弱技术的比较疗效对于手术规划至关重要.

研究的目的:

评估和比较四种不同的下方斜削弱手术对眼睛扭动的影响.
具体来说,要评估下斜回落 (IOR),回落和前置位置 (RAP),埃利奥特和南金 (EN) 前置位置,以及前置和鼻腔位置 (ANT).

主要方法:

对72名患者 (>10年) 的回顾性审查,这些患者经历了IOOA的下斜衰弱.
106只眼睛根据手术程序被分为四组.
术前和术后测量 (1周,4周,3个月) 的盘角 (DFA) 被用来评估循环扭转的变化.

主要成果:

这四种手术均在术后3个月后导致了显著的循环扭转转移.
前部和鼻腔转移 (ANT) 显示出最大的外循环扭转 (16.62° ± 8.72°) 的平均减少,明显超过IOR,RAP和EN.
除了IOR以外的所有手术中,与手术前的DFA相关的DFA减少.

结论:

所有评估的下斜减弱程序都有效地减少了excyclotorsion.
前鼻转移 (ANT) 似乎是最有效的技术,以减少眼睛扭转在患有下斜过度的患者.

Transformation of Plane Stress

Transformation of Plane Stress

Studying stress transformation is essential in understanding how stress components within a material, like a cube under plane stress, change with rotation. This change is analyzed by considering a prismatic element within the cube. As the element rotates, the stress components acting on it—both normal and shearing stresses—change in magnitude and orientation. This change is quantified using trigonometric functions of the rotation angle, relating the forces acting on the rotated element's...
