Objective: To develop a practical, inexpensive system for 3-dimensional ultrasound biomicroscopic imaging of the anterior segment with a commercially available high-frequency ultrasound imager and a personal computer. Methods: Sequential, high-frequency, ultrasound biomicroscopic images of the anterior segment were obtained with a motorized scanning control arm designed in our imaging laboratory. Images were acquired by a personal computer-based video capture device. Ultrasound slice data were then reconstructed as 3- dimensional volumetric images by a personal computer and commercially available software. Results: Four 3-dimensional visualization formats were developed to enhance the clinical utility of high-frequency ultrasound. Rotational animation sequences were created that detailed the extent and anatomy of a filtering bleb, intraocular lens subluxation, focal angle closure from an iridociliary cyst, intraocular foreign bodies, and an iris tumor. Conclusions: Three-dimensional, high-frequency ultrasound of the anterior segment enhances our ability to visualize spatial relationships between adjacent anatomic structures. The low cost and case of use of this system make widespread clinical application practical.
