Purpose: To survey the existing practice of management of acute posterior segment IOFB in Hong Kong and to evaluate the prognostic factors for visual outcomes. Methods: The records of all 24 patients with acute posterior segment IOFb managed in all public hospitals in Hong Kong in three years (from 1998 to 2000) were reviewed. The mechanism of injury, presenting visual acuity, investigation, surgical management, complications and outcomes were analyzed. Results: 83% of the injuries were work-related. CAT scan was performed in 16/24 (67%) patients. Posterior vietrectomy was carried out in 15/24 (62.5%) patients with removal of IOFB by giant magnet in 13/24 (54%) patients. The visual acuity was improved in 14/24 (58%) patients and they retained best-corrected visual acuity of 0.1 or better. Conclusion: The management of acute posterior segment IOFB during the study period was variable among different hospitals. The initial presenting visual acuity is the strongest predictive factor for the final visual outcomes.
