B-scan ultrasonography of the retina and vitreous.
We feel that ultrasonography performed prior to vitreous surgery should be performed or at least observed by the operating surgeon or the assistant. The actual dynamic scanning process allows much more information about the status of the eye than looking at static pictures. Although vitreous surgery can be performed without preoperative ultrasonographic examination, we feel that ultrasonography can provide the surgeon with valuable, accurate information about the status of the vitreous humor and the retina.
