title: "Real-time" immersion B-scan and C-scan techniques in ophthalmic diagnosis.
abstract: The advent of new techniques in vitreous surgery has added an impetus to improve ultrasonic examination of the vitreous cavity. Rapid B-scanning is vital in the diagnosis of vitreo-retinal pathology when opacity prevents biomicroscopical examination. Serial B- and C-scan sectioning have also proved essential in the study of tumours. The C-scan is of particular value in the study of traction retinal detachments and tumours.
