PURPOSE: To assess the benefit of three-dimensional (3D) ultrasound biomicroscopy in examination of the posterior iris and ciliary body. METHODS: 3D visualization of the anterior eye section was achieved through extension of the existing ultrasound biomicroscope system (Humphrey Instruments). Visualization of posterior iris and ciliary body pathologies in three patients was performed with a 3D reconstruction technique of B scans. RESULTS: The extended ultrasound system provided 3D visualization of alterations in the posterior iris region, i.e., iris cysts, ciliary body cysts, solid tumors of the ciliary body and iris. CONCLUSIONS: 3D ultrasound biomicroscopy yields extended diagnostic findings regarding iris and ciliary body pathology. This method offers improved assessment of the posterior surface of the iris and the volume of the ciliary body. Furthermore, these data could be useful for computer simulation and procedures and for calculation of a better understanding of the function of the ciliary body in the accommodation process.
