Aim: to study the postoperative outcomes of vitrectomy for intraocular foreign bodies in patients with ocular injury

Study Design: Retrospective Case Series

Method: Patient registry of patients with cases of intraocular foreign bodies (IOFB) in patients with ocular injury who received vitrectomy at Thammasat University Hospital between October 2012-September 2016 were examined. Statistical analysis exact fisher’s test to examine the treatment outcome and the relationship of different factors that may affect the treatment outcome.

Results: Of all 25 patients, 23 were male (92%), 2 were female (8%) mean age 34.04± 8.97 years. 12 right eyes (48%) and 13 left eyes (52%). Mean duration between injury and operation was 23.24±46.18 days.19 patient’s eyes (76%) had postoperative visual acuity (VA) of 20/200 or better. 6 patient’s eyes had postoperative VA lesser than 20/200 (24%). One eye resulted in no light perception. No factor was found to have statistically significant association.

Conclusion: The study results have not found any other statistical significance in occurrence relations between postoperative visual outcomes and other examined factors. However, IOFBs 3mm or smaller in size are associated with favorable postoperative visual outcomes (p=0.076).
