摘要
目的探讨磁共振成像三维（3D）打印技术在高度近视后巩膜加固术前术后的应用价值。方法高度近视后巩膜加固术20例（30眼），术前及术后均行磁共振三维成像序列检查，其磁共振影像数据通过交互式医学图像控制系统软件进行重建，生成三维模型格式文件，并通过三维打印程序软件转化成可识别的路径文件，最后通过三维打印机等比例打印出三维立体眼球、眼肌、视神经及后巩膜加固条带模型。结果根据高度近视患者的磁共振三维成像数据成功打印出个体化等比例眼球、眼肌、视神经及后巩膜加固条带的三维实体模型。结论三维打印制作的等比例眼球、眼肌、视神经及后巩膜加固条带实体三维模型，有助于后巩膜加固术前评估及术后评价，具有一定的应用价值。
Objective To investigate the application value of three-dimensional （3D） printing technology of MRI in posterior sclera reinforcement surgery for high myopia. Methods The data of 29 eyes of 30 patients with high myopia were collected and they underwent posterior sclera reinforcement （ PSR ）. All cases received 3D MRI before and after PSR. The MRI data of patients were reconstructed by using materialise＇s interactive medical inkage control system software to generate stereo lithography （ STL ） file, then STL fide was turned into print recognizable path file by printing program software,and finally 3D eyeball, ocular muscles, optic nerve and PSR strip model were printed proportionally by using 3D printers. Results According to MRI image data, 3 D solid individualized proportional model of eyeball, ocular muscles, optic nerve and PSR strip were successfully printed. Conclusion Three-dimensional proportional model of eyeball, ocular muscles, optic nerve and PSR strip made by 3D printers are contribute to preoperative and postoperative PSR with the certain value in application.
