·AIM:To evaluate the effects of complex trabeculectomy in treatment of secondary glaucoma after silicone oil filling.·METHODS:Eleven cases 11 eyes with secondary glaucoma after silicone oil filling were treated with complex trabeculectomy since Oct.2003 to Dec.2008.Clinical observations were carried out on filtering bleb,intraocular pressure(IOP)and vision.·RESULTS:High rate of functional filtering bleb formation was achieved after complex trabeculectomy.IOP was 52.3±11.5mmHg before operation and 15.4±8.3mmHg after operation,IOP was significantly dropped(P<0.01).4 eyes(36%)had vision improved and 5 eyes(45%)had equal vision with preoperation,2 eyes(18%)with vision decreased.·CONCLUSION:Complex trabeculectomy can treat secondary glaucoma after silicone oil filling effectively.·
