A man aged 30 years presented with a history of floaters OD following history of blunt trauma with a cricket ball 1 week ago. Unaided visual acuity was 20/20 OU. OS was normal. OD showed vitreous base avulsion from 5 to 9'o clock position in a typical bucket handle appearance. Ultra-wide-field (Optos) imaging with eye steered inferiorly showed vitreous base avulsion (figure 1). Rest of the ocular examination was within normal limits. The patient was reassured and advised regular follow-up.
