AIM:To explore possible causes of early postoperative elevated intraocular pressure caused by proliferative diabetic retinopathy(PDR)vitrectomy. METHODS:Totally 72 cases(100 eyes)which have performed vitrectomy for proliferative diabetic retinopathy were retrospectively analyzed to observe the incidence of postoperative ocular hypertension, and the relevant factors that caused postoperative high intraocular pressure were statistically analyzed. Early postoperative ocular hypertension diagnostic criteria: any time after 2 weeks of non-contact tonometer measured IOP> 25mmHg(1mmHg=0.133kPa). RESULTS:High intraocular pressure after vitrectomy occurred in 27 eyes(27%), the incidence of male and female were 27.27%, 26.79%, the difference was not statistically significant(P>0.05). Eyes filled with balanced liquid filling incidence rate of 30.95%, 6.25%, and the difference was statistically significant(P0.05). Incidences of intraoperative panretinal photocoagulation and additional retinal photocoagulation group were 41%, 20%, and the difference was statistically significant(P |
