AIM: To analyze the law and the therapeutic schedule of postoperative intraocular hypertension of posterior vitrectomy combined with intraocular plombage.

METHODS: The visual acuity of 198 eyes after posterior vitrectomy combined with intraocular plombagefrom January 2009 to January 2011 in our hospital was monitored. Cases with intraocular hypertension were observed and analyzed.

RESULTS: Among the 198 cases, there were 53 cases with early postoperative intraocular hypertension, showing that the incidence was 26.8%. The incidence was similar among DR, rentina vascular diseases, macular hole and rhegmatogenous retinal detachment, with no statistic significance(P>0.05). The incidence rates were also similar between the silicone oil plombage group and inert gas plombage group, with no statistic significance(P>0.05). But the incidence rates were different between the groups with and without cataract extraction and IOL implantation, showing statistic significance(P<0.05).

CONCLUSION: The incidence of intraocular hypertension after vitrectomy combined with intraocular plombage has little to do with the protopathy and the filler, but is related with the surgical method. Releasing partial gas or anterior chabeer aqueous humbor fluid is an effective mean to lower IOP.
