Preoperative ultrasound scans (a) of the patient demonstrates obvious traction adjacent to the disc (blue arrow). Ultrasound B scan at the 5-year follow-up shows that the traction remains relieved in the area adjacent to the disc (b). The patient’s vision recovered to 6/12 and has been maintained over 5 years. In the Ultrasound, the blue arrow points to the tractional detachment preoperatively and the yellow arrow points to the released traction postoperatively
