孔源性视网膜脱离的静态三维超声重建

Static three dimentional reconstruction of sonography in rhegmatogenous retinal detachment

目的应用静态三维超声重建的方法显示孔源性视网膜脱离的立体结构形态和视网膜裂孔。方法应用Ｈｐｓｏｎｏｓ１５００多功能超声诊断仪，以计算机控制的步进马达带动７．０ＭＨｚ换能器采集二维图像，经Ｔｏｍｔｅｃ计算机成像系统重建三维图像。结果在１３例１４只眼中成功完成了静态三维超声重建，显示了视网膜的立体结构及部分视网膜裂孔。结论静态三维超声重建可提高对视网膜脱离的空间结构关系的认识能力，为屈光间质混浊的病例发现视网膜裂孔提供了新的诊断方法。

Objective To present stereoscopic image of rhegmatogenous retinal detachment with three dimentional reconstruction of sonography. Methods Ultrasound data were collected by Hpsonos 1 500 and 7.0MHz transducter with the motor controlled by computer.Three dimentional image were reconstructed with Tomtec echoscan. Results Three dimentional image were successfully reconstructed in 14 eyes of 13 cases of retinal detachment include 3 eyes of 3 cases with opaque refractive medium showing stereosopic image of retina and some retinal tears. Conclusion Static three dimentional reconstruction of sonography might enhance the ability to visulize spatial anatomic structure of retina and offer a new method to find retinal tears in patients with opague refractive medium.
