Epidemiology, clinical profile and factors, predicting final visual outcome of pediatric ocular trauma in a tertiary eye care center of Central India.

Abstract

Purpose:Ocular trauma constitutes an important cause of preventable visual morbidity worldwide. This study was done to study the incidence, sociodemographic pattern, and clinical profile of ocular trauma in pediatric age group. Also to evaluate the factors influencing final visual outcome in these patients.Methods:This was a prospective interventional study concerning ocular trauma in pediatric patients up to 16 years of age of either sex. Various variables having an impact on final visual outcome were studied, and results were analyzed using statistical indices – relative risk, Chi-square test, P value, and linear regression analysis.Results:A total of 220 cases of trauma were evaluated with the mean age being 8.74 ± 3.93 years, males were predominantly affected and open globe injuries outnumbered blunt injuries. Penetrating injuries accounted for 67.79% cases of open globe injury, rupture being the least (2.54%). Stepwise multiple linear regression analysis executed, showed the best predictors in the descending order for final visual outcome were presenting visual acuity, size of corneal tear, type of injury, zone of injury, time period between injury and treatment with a variance of 35.9%, 6.3%, 5.3%, 3.7%, and 2.7%, respectively. All above variables were also found to be statistically significant (P < 0.05) on Chi-square test.Conclusion:We report the first study on the epidemiology and clinical outcomes of pediatric ocular trauma in central India. Poor initial Visual Acuity and posterior segment involvement adversely affect the visual outcome. Early medical treatment and globe-salvaging repair should be done in all eyes suffering from trauma.
