AIM:To discuss the causes and managements of exposure of glaucoma valve(GV) device implants. METHODS:A retrospective analysis of 8 cases with GV exposure was conducted. RESULTS:The GV exposure occurred from 6 to 31 months after implantation. Different methods may be applied to manage GV exposure according to the different causes. Follow-up was performed after operation and the effect was good. CONCLUSION:The causes of GV exposure are related to surgery methods, the version of GV, the category of disease and so on.
