A new classification for epidemiological study of mechanical eye injuries / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>Considering the difficulty in classifying some cases with eye trauma by Birmingham Eye Trauma Terminology (BETT) in our epidemiological study, we introduce a new classification for epidemiological study of mechanical eye injuries based on BETT.</p><p><b>METHODS</b>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 10 718 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.</p><p><b>RESULTS</b>Of 10 718 patients (11 227 eyes) with mechanical eye injuries, the following cases cannot be classified by BETT: 1 488 patients (1 559 eyes) with merely orbital or ocular adnexa injury, 1 961 (2 054) globe injuries associated 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 associated 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.</p><p><b>CONCLUSION</b>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 classification to some extent. It is hoped that other ophthalmologists present better ones to make the classification more perfect.</p>

Laser in situ keratomileusis surgery is not safe for military personnel / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To investigate the relationship between eye injury and laser in-situ keratomileusis (LASIK) surgery in military personnel.</p><p><b>METHODS</b>This retrospective study collected the data from 27 evacuation hospitals of Chinese army. All medical records of eye injuries in military personnel admitted to the 27 hospitals between January 2006 and December 2010 were reviewed. Patients'detailed information was analyzed, including the injury time, place, type, cause, as well as examination, treatment and outcome.</p><p><b>RESULTS</b>There were 72 eye-injured patients who had been treated by LASIK before. The incidence was rising year by year. Among them, 69 patients were diagnosed with mechanical ocular injury and 3 with non-mechanical ocular injury; 29 patients had traumatic flap-related complications and 21 patients need surgery. There was statistical difference when compared with those having no refractive surgery history. Visual acuity recovered well at discharge.</p><p><b>CONCLUSION</b>There is a high risk of potential traumatic flap problems after LASIK and it is not recommended in army service.</p>

Epidemiology of eye injuries sustained by military personnel in China / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To investigate the epidemiological characteristics of eye injuries sustained by military personnel in Chinese army.</p><p><b>METHODS</b>Eleven military evacuation hospitals located in different regions were selected for this study. We reviewed all the medical records of eye injuries sustained by military personnel between January 2005 and December 2009. Patients'information was collected. All data were put into database and analyzed statistically.</p><p><b>RESULTS</b>Totally there were 415 inpatients with eye injuries (442 eyes) and their mean age was 24.40 years. Eye injury accounts for 13.51% of all eye diseases in this study. From 2006 to 2009, the number of eye injury increased gradually. Among them, 175 (42.17%) were injured in leisure time, and 145 (34.94%) in working time. Twenty-two (5.30%) patients had an eye surgery or history of eye disease before injury. In all, 246 patients (59.28%) were sent to evacuation hospital within 24 hours and 64 (56.64%) underwent surgeries in 24 hours after injury. There were 389 patients (93.73%) hospitalized for 1 time. Visual acuities of 187 eyes (42.31%) were grade 1 (larger than or equal to 20/40) after injury. When discharge, 349 eyes (78.96%) obtained a visual acuity of grade 1.</p><p><b>CONCLUSION</b>Eye injury has a very frequent incidence in Chinese army and much more attention should be paid to prevent it.</p>
