Abstract
Objective To analyse the causative factors of high intraocular pressure (IOP) after vitrectomy combined with silicon oil tamponade. Methods The data of 78 eyes of 78 patients who underwent pars plana vitrectomy combined with silicon oil tamponade between July 2013 and January 2015 in our hospital were retrospectively analyzed. The follow-up time was 12 months, and the high IOP was defined as IOP≥24 mmHg(1 mmHg=0.133 kPa). Statistical methods were used to analyze the possible causative factors of postoperative high IOP. Results Postoperative high IOP occurred in 27 cases (34.62%). There was no significant difference in age, gender, diabetes mellitus, previous intraocular surgery or ocular trauma between high IOP group and normal IOP group(P> 0.05). Logistic multivariate regression analysis showed that the OR values of high myopia, combined with lentectomy, emulsification of silicone oil, uveitis and time of silicon oil tamponade over 6 months were 10.569(1.519-73.555), 15.325(1.470-159.731), 17.828(2.268-140.171), 25.783(2.579-257.759), 4.327(1.436-13.035), respectively. They were independent risk factors of high IOP after surgery. Conclusion The risk factors of high IOP after vitrectomy combined with silicon oil tamponade from high to low are uveitis, emulsification of silicone oil, combining with lentectomy, high myopia and time of silicon oil tamponade for too long.
