Ultrasonic examination is an essential investigation in most patients awaiting vitrectomy. Rapid B-scanning of the vitreous is described utilising a new system capable of high resolution and good tonal quality. Several patterns of haemorrhagic invasion of the vitreous cavity are illustrated, together with detachment, collapse, and retraction of the vitreous gel.
