# Relationship Between Ocular Trauma Score and Computed Tomography Findings in Eyes with Penetrating Globe Injuries: A Preliminary Study

## TL;DR

This study explores how CT scan findings relate to ocular trauma scores in patients with eye injuries, showing that CT findings correlate with injury severity.

## Contribution

The study identifies specific CT findings associated with different ocular trauma score categories in penetrating globe injuries.

## Key findings

- Globe wall irregularity and asymmetric anterior chamber depth were the most common CT findings.
- A significant negative correlation exists between CT findings and ocular trauma scores.
- Clinical examination remains essential despite the value of CT findings in assessing trauma severity.

## Abstract

Background/Objectives: The aim of this study was to evaluate computed tomography (CT) findings in penetrating globe injuries and their relationship with ocular trauma scores (OTSs). Methods: Patients with penetrating globe injuries who had orbital CT images were included in this study. Demographics, injury zone, and ophthalmologic exam data were collected retrospectively. OTSs and categories were determined. Orbital CT images were evaluated by a radiologist to determine decreased globe volume, globe wall irregularity, chorioretinal layer thickening, lens dislocation, asymmetric anterior chamber depth (ACD), abnormal vitreous density, and intraocular air presence. Results: This study included 30 eyes of 30 patients. The majority of patients (n = 20, 66.7%) had Zone I injuries. The most common CT findings were globe wall irregularity (53.3%) and asymmetric ACD (53.3%). No CT findings were observed in 10 patients (33.3%). Globe wall irregularity was the most frequent CT finding in the OTS II category, while asymmetric ACD was most frequent in the OTS IV category. All patients with decreased globe volume, lens dislocation, abnormal vitreous density, and ≥3 CT findings were in the OTS II category. A significant negative correlation was found between the number of CT findings and OTS (r = −0.644, p < 0.001), and a significant positive correlation was found between the number of CT findings and clinically measured wound size (r = 0.600, p < 0.001). Conclusions: CT findings help assess ocular trauma severity, but clinical examination remains essential for accurate diagnosis.
