Methods： A retrospective investigation was carried out in 31 hospitals from January 2005 to December 2010. All medical records of inpatients with eye injuries were reviewed. A total of l0 718 patients （11 227 eyes） were diagnosed as mechanical eye injuries. All mechanical eye injuries were tried to be classified using BETT. While some eye injuries were difficult to categorize. We recorded the injury type and case number. A new classification based on BETT was also used for the same project. Results： Of 10 718 patients （11 227 eyes） with me- chanical eye injuries, the following cases cannot be classi- fied by BETT： 1 488 patients （1 559 eyes） with merely orbitalor ocular adnexa injury, 1 961 （2 054） globe injuries associ- ated with orbital or ocular adnexa injury, 271 （284） ocular surface foreign body （OSFB） or ocular wall foreign body （OWFB）, 77 （89） contusion, 9 （11） lamellar laceration asso- ciated with OSFB or OWFB, 29 （30） rupture associated with OSFB, OWFB or intraocular foreign body and 60 （62） lace- ration associated with OSFB or OWFB. While according to our new classification, all eye injuries can be categorized without any difficulty. Conclusion： Difficulty in classifying some eye injuries in epidemiological study by BETT brings some trouble to our study, which can be solved by our new eye injury clas- sification to some extent. It is hoped that other ophthal- mologists present better ones to make the classification more perfect.展开更多
