目的：探讨青光眼减压阀植入术后减压阀暴露原因及处理。 方法：对我院收治的8例青光眼减压阀植入术后减压阀暴露者，分析其暴露原因，并采用相应的处理方法。 结果：减压阀暴露发生时间为术后6~31mo，经结膜修补或再次植入新阀后，随访6~24mo效果良好。 结论：青光眼减压阀暴露的原因与手术技巧、患眼的病变等因素有关，所以术中应积极避免暴露因素。

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. During the course of surgery, we should eliminate the risk factors of GV exposure as soon as possible.
