Epidemiological Characteristics And Prognostic Factors Of 1046 Patients With Open Ocular Trauma

Objective:Retrospective analysis of 1046 cases of open eye injury(OGI)patients in Lanzhou University Second Hospital.,to understand the epidemiological characteristics of OGI patients and factors affecting visual prognosis,to provide guidance for OGI prevention measures in this area.Methods:Through the enrollment of 1046(1055 eyes)OGI patients' electronic medical records between Lanzhou University Second Hospital from January 2012 to December 2017,the epidemiological data(age,gender,ethnicity,region,eye,occupation,referral,time of visit,cause of injury)were collected.And analysis of factors affecting prognostic visual acuity(first visit vision,initial repair time,type of injury,Zone of injury,anterior chamber hemorrhage,Lens breach,relative afferent pupillary disorder,vitreous hemorrhage,retinal detachment,endophthalmitis),analyze the influencing factors of endophthalmitis,compare the initial visual acuity and final visual acuity,and analyze the prognostic evaluation of OTS score in OGI patients.The count data and grade data of this study were described by the number of cases(percentage),and the chi-square test or rank sum test was used for comparison between groups.Logistic regression was used to analyze the influencing factors of prognostic visual acuity.Results:Among the 1046(1055 eyes)OGI patients,the male patients were significantly higher than the females(the male to female ratio was 4:1);the incidence rate of the Han nationality was significantly higher than that of the ethnic minorities(4.28:1),among the minority patients,the Hui nationality accounted for The proportion is the largest(53.0%);the proportion of ethnic minorities in children is significantly higher than that in adults(?2=26.712 p<0.001);the highest rate of visits from Dingxi City is the lowest in Jinchang City;the right eye accounts for 48.7%.The left eye accounted for 50.4%;the eyes accounted for 0.9%;OGI patients had the largest number of occupations,followed by workers;referrals accounted for 84.32%;direct visits accounted for 15.68%;the rate of visits within 24 hours after injury was 72.90%,within 3 days The visit rate was 85.40%,and the visit rate was 95% within 7 days.Among the causes of injury,the sharp injury was the highest,followed by blunt injury and splash injury;Initial repair time>24h,initial visual acuity<0.1,rupture ocular injury,Zone III injury,anterior chamber hemorrhage,Lens breach,relative afferent pupillary disorder,vitreous hemorrhage,retinal detachment,endophthalmitis are risk factors for visual prognosis.Initial repair time>24h,Lens breach,Intraocular tissue prolapse,intraocular foreign body,penetrating ocular injury,and Zone I injury are risk factors for endophthalmitis.End of eye Vision is associated with primary vision,and final vision is superior to primary vision after treatment;OTS may have predictive value in final VA in OGI patients.Conclusion: 1.The peak age of 1.1046 cases of ocular trauma patients was 0~5 years old,male to female ratio: 4:1;the proportion of ethnic minorities in children was significantly higher than that of ethnic minorities in adults(?2=26.712 p < 0.001);OGI is mostly caused by farmers and workers;the cause of injury is more common in sharp injuries.2.Initial repair time>24h,initial visual acuity<0.1,rupture ocular injury,Zone III injury,anterior chamber hemorrhage,Lens breach,relative afferent pupillary disorder,vitreous hemorrhage,retinal detachment,endophthalmitis are risk factors for visual prognosis.3.Initial repair time>24h,Lens breach,Intraocular tissue prolapse,intraocular foreign body,penetrating ocular injury,and Zone I injury are risk factors for endophthalmitis.4.The final visual acuity after treatment is better than the initial visual acuity.5.OTS may have predictive value in final vision.
