Abstract

The medical records of 206 eyes of 206 consecutive patients who underwent pars plana vitrectomy between March 1994 and October 1998, were reviewed retrospectively to determine the incidence and risk factors of postoperative intraocular pressure elevation. The mean follow-up period was 104.2 weeks. Early(within 7 days of surgery)and late postoperative intraocular pressure elevation(>21mmHg)occurred in 83 eyes(40.3%)and 84 eyes(40.7%), respectively. Injection of the gas increased the incidence of early postoperative intraocular pressure elevation significantly(Chi-square univariate analysis;P=0.046, Multivariate logistic regression analysis;odds ratio=1.928, confidence interval 1.079~3.480). Patients undergoing pars plana vitrectomy with gas tamponade must be carefully followed after surgery due to high incidence of postoperative intraocular pressure elevation.
