The Association Between Computerized Tomography Findings and Ocular Trauma Score in Open Globe Injury: The Prognostic Value of Imaging

Abstract

Purpose: The aim of this study was to evaluate the association between CT findings and Ocular Trauma Score (OTS) in open globe injury. Methods: In 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. Results: Mean 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). Conclusions: The type and number of CT findings may help to predict the OTS stage and visual prognosis in eyes with open globe injury.
