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.

In Brief

The type and number of CT findings may be valuable in staging and identifying the prognosis of open globe injuries; the overall imaging findings may be as helpful in grading ocular trauma severity and predicting visual outcome as clinical data itself.
