AIM:To analyse the correlative factors of eyeball extraction . METHODS: The data of 107 cases with eyeball extraction were collected from July 2005 to July 2009,and analysed with classification by original pathogen and trauma history. RESULTS:The primary causation causing eyeball extraction was secondary absolute glaucoma. The primary causation causing eyeball extraction was complications from operation of cataract and glaucoma in 49 cases of trauma history. The absolute glaucoma was the primary causation in 58 cases without trauma history. CONCLUSION:It is very important to propagandize knowledge about glaucoma. The cases of ocular trauma should be treated timely and exactly, the oculist from primary hospital should be trained in clinical skill.
