目的：本研究的目的是评估三维超声生物显微镜检查后虹膜和睫状体的好处。研究方法：通过扩展现有的超声生物显微镜系统（Humphrey Instruments）实现眼前节的三维可视化。三名患者的后虹膜和睫状体病变的可视化进行了三维重建技术的B扫描。结果如下：扩展的超声系统提供了虹膜后区改变的三维可视化，即虹膜囊肿、睫状体囊肿和睫状体和虹膜的实体瘤。结论：三维超声生物显微镜可提供有关虹膜和睫状体病理的扩展诊断结果。该方法提供了虹膜后表面和睫状体体积的改进评估。此外，这些数据可以用于计算机模拟和计算程序，以更好地理解睫状体在调节过程中的功能。
Purpose: The aim of this study was to assess the benefit of the three-dimensional ultrasound biomicroscopy in examination of the posterior iris and ciliary body. Methods: Three-dimensional visualisation of the anterior eye section was achieved through extension of the existing ultrasound biomicroscope system (Humphrey Instruments). Visualisation of posterior iris and ciliary body pathologies in three patients was performed with a three-dimensional reconstruction technique of B-scans. Results: The extended ultrasound system provided three-dimensional visualisation of alterations of the posterior iris region, i.e. iris cysts, ciliary body cysts and solid tumours of the ciliary body and iris. Conclusions: The three-dimensional ultrasound biomicroscopy yields extended diagnostic findings regarding iris and ciliary body pathology. This method offers an improved assessment of the posterior surface of the iris and the volume of the ciliary body. Furthermore, these data can be useful for procedures in computer simulation and calculation for a better understanding of the function of the ciliary body in the accommodation process.
