Predictive factors and outcomes of posterior segment intraocular foreign bodies

Purpose To identify the predictive factors for anatomical and visual outcomes in posterior segment intraocular foreign body (IOFB) patients managed by pars plana vitrectomy (PPV). Methods A retrospective chart review was performed for 77 patients, who had PPV for IOFBs removal between January 2001 a...

Methods A retrospective chart review was performed for 77 patients, who had PPV for IOFBs removal between January 2001 and July 2007. Univariate and multivariate analyses were conducted to evaluate the predictive factors. Results The mean age of the patients was 33.4 years.
