Ultrasound biomicroscopy in refractive surgery
Journal of Cataract and Refractive Surgery, 1994The need for improved methods of assessing corneal topography arose from the advent of refractive surgery. Ultrasound biomicroscopy (UBM) is a high-resolution technique that uses high-frequency transducers to evaluate the cornea. We conducted a pilot study to assess the cornea after refractive surgery using UBM.

In vivo ultrasound biomicroscopy
1993 Proceedings IEEE Ultrasonics Symposium, 1993A very high frequency ultrasonic biomicroscopy system (30-130 MHz) using a B-scan combined with a new Z-scan technique for in vivo imaging of the skin has been developed. To get high lateral resolution and a good signal to noise ratio, we utilized a very narrow focused single element ceramic transducer as used in conventional acoustic microscopy ...

Ultrasound Biomicroscopy in Glaucoma
2016Ultrasound biomicroscopy (UBM) is a high-resolution ultrasound technique, which allows noninvasive in vivo imaging of the anterior ocular segment. It shows excellent images of the anterior chamber angle, and the ciliary body. In glaucoma, UBM can be used to image the changes of the ocular structures after glaucoma surgery, such us filtering blebs and ...
