[Vitrectomy for extraction of intraocular foreign bodies]
1Department of Ophthalmology, First Affiliated Hospital, Henan Medical University, Zhengzhou.
Objective:
To evaluate the effect of treatment of intraocular foreign bodies (IOFBs) with vitrectomy and its influential factors.
Methods:
A retrospective research was done on 517 in-patients having undergone extraction of IOFBs with vitrectomy.
Results:
Postoperatively, the successful rate of the extraction of IOFBs was 97.6%, the rate of cases with useful vision (0.05 to 0.4) increased from preoperative 12.5% to 23.2% and that with good vision (0.5 and better) from 7.2% to 17.0% (P < 0.005). When IOFBs were located in anterior segment, vitreous and retina, the increasing rates of cases with useful vision respectively were 44.4%, 25.1% and 10.7%, and that of good vision were 26.3%, 12.7% and 2.7%.
Conclusions:
Vitrectomy is favorable for the extraction of IOFBs, the increase of postoperative vision and the management of complications.
