PURPOSE
To quantitatively analyze the shape of eyes with high myopia and provide assistance for posterior scleral reinforcement (PSR) using high-resolution three-dimensional (3D) magnetic resonance imaging (MRI).
METHOD
In all, 260 eyes of 134 patients with high myopia were assessed in this study; 120 emmetropic volunteers were enrolled as a control group. The subjects were examined using 3D T2-weighted CUBE sequences.
RESULTS
The eyeballs' axial, horizontal, and vertical lengths were longer and their volume was larger in the subjects with high myopia than in those with emmetropia. The sites of the four recti and optic nerve attachment to the eye were clearly seen on 3D MRI, and the geometric information could be quantified for PSR preparation. The scleral strip was revealed by 3D MRI after surgery.
CONCLUSIONS
3D MRI can quantitatively analyze the shape of eyes with high myopia. 3D MRI examination might be necessary before and after PSR for preoperative preparation and postoperative assessment.
目的
使用高分辨率三维（3D）磁共振成像（MRI）定量分析高度近视眼的形态，并为后巩膜加固术（PSR）提供辅助。
方法
本研究共评估了134例高度近视患者的260只眼；招募120名正视眼志愿者作为对照组。使用3D T2加权CUBE序列对受试者进行检查。
结果
高度近视患者的眼球轴长、水平径和垂直径更长，体积更大。在3D MRI上可以清晰看到四条直肌和视神经附着于眼球的部位，并且可以为PSR手术准备量化几何信息。术后3D MRI显示了巩膜条带。
结论
3D MRI可以定量分析高度近视眼的形态。在PSR手术前后进行3D MRI检查对于术前准备和术后评估可能是必要的。
