目的：探讨玻璃体切除术后高眼压的原因及处理方法。
方法：回顾性分析2007-01/2010-03在院行玻璃体切除术482例511眼患者术后发生高眼压的原因及处理方法。
结果：患者482例511眼中有140例141眼发生高眼压，发生率为27.6%。C3F8填充和硅油填充患者高眼压的发生率差异有统计学意义(P<0.01)。联合环扎和未环扎患者高眼压的发生率差异有统计学意义(P<0.05)。无晶状体眼和有晶状体眼患者高眼压的发生率差异有统计学意义(P<0.01)，外伤性和非外伤性患者术后高眼压发生率差异有统计学意义(P<0.01)。
结论：巩膜外环扎、C3F8填充、无晶状体眼及外伤是玻璃体切除术后高眼压的高危因素。

[Abstract]
AIM: To investigate the cause and treatment of high intraocular pressure(IOP)after pars plana vitrectomy(PPV).
METHODS: Totally, 482 patients(511 eyes)underwent PPV from January 2007 to March 2010, were reviewed to explore the mechanism and treatment of high IOP after PPV.
RESULTS: High IOP occurred in 140 patients(141 eyes), the rate of IOP elevation was 27.6%. The rate of IOP elevation was significantly between C3F8 and silicone tamponading(P<0.01). The rate of IOP elevation with sclera buckling was significantly different from that without sclera buckling(P<0.05). The rate of IOP elevation in aphakia was different from phakia(P<0.01). And it was also had significant difference between traumatic and nontraumatic ones(P<0.01).
CONCLUSION: The risk factors of IOP elevation include sclera buckling, C3F8 tamponade, aphakia and trauma.
