title: Combined B- and  A-scan ultrasonography in the management and preoperative assessment of vitreo retinal pathology.
abstract: Newer surgical techniques such as vitrectomy instrumentation and microsurgery now allow us to take a full advantage of ultrasonic evaluation of vitreal-retinal pathology. The ultrasonic techniques of A- and B-scan as well as M-scan allow us to more adequately evaluate the opaque vitreous, retinal detachment, traumatic changes to the globe, thus directing the newer surgical techniques to achieve therapeutic results never previously possible.
