Incidence and clinical features of pediatric ocular trauma in a population-based cohort

Abstract

PurposeTo report the incidence and clinical characteristics of pediatric ocular and adnexal injuries diagnosed over a 10-year period in Olmsted County, Minnesota. MethodsThis multicenter retrospective, population-based cohort study included all patients <19 years of age in Olmsted County diagnosed with ocular or adnexal injuries from January 1, 2000, through December 31, 2009. ResultsA total of 740 ocular or adnexal injuries occurred during the study period, yielding an incidence of 203 (95% CI, 189-218) per 100,000 children. Median age at diagnosis was 10.0 years, and 462 (62.4%) were males. Injuries presented to the emergency department or urgent care setting most frequently (69.6%) and often occurred while outdoors (31.6%) during summer months (29.7%). Common injury mechanisms included blunt force (21.5%), foreign bodies (13.8%), and sports activities (13.0%). Isolated anterior segment injuries occurred in 63.5% of injuries. Ninety-nine patients (13.8%) had visual acuity of 20/40 or worse at initial examination, and 55 patients (7.7%) had visual acuity of 20/40 or worse at final examination. Twenty-nine injuries (3.9%) required surgical intervention. Significant risk factors for reduced visual acuity and/or the development of long-term complications include male sex, age ≥12 years, outdoor injuries, sport and firearm/projectile injury mechanism, and hyphema or posterior segment injury (P < 0.05). ConclusionsMost pediatric eye injuries are minor anterior segment injuries with infrequent long-lasting effects on visual development.
