Abstract
PURPOSEThe aim of this study was to evaluate the association between CT findings and Ocular Trauma Score (OTS) in open globe injury. METHODSIn 182 eyes with open globe injury, CT findings were categorized into 5 major types: scleral irregularity with decreased globe volume, dislocation of the crystalline lens, abnormal vitreous density, thickening of the chorioretinal layer, and intraocular foreign body/air. Association between different types and number of CT findings with OTS stages were evaluated through a multivariate analysis. RESULTSMean age of the patients was 38 ± 8.5 years. The most common CT findings were severe scleral irregularity or globe collapse (71.9%) and abnormal vitreous density (56%). The most common OTS stages were II (44.5%) and I (30.7%). In multivariate analysis, abnormal vitreous density (odds ratio [OR] = 2.11, p < 0.001), chorioretinal thickening (OR = 1.89, p < 0.001), and intraocular foreign body/air (OR = 1.58, p = 0.001) were associated with more advanced OTS stages (I or II). Mean OTS in eyes with 1, 2, and 3 CT findings were 66 (stage III), 47 (stage II), and 37 (stage I), respectively (p value = 0.008). Presence of 2 (OR = 2.46, p < 0.001) and 3 (OR = 2.92, p < 0.001) CT findings were associated with more advanced OTS stages (I or II). CONCLUSIONSThe type and number of CT findings may help to predict the OTS stage and visual prognosis in eyes with open globe injury.
