Open globe injuries are diagnosed by ophthalmological examination. The purpose of this study is to determine the sensitivity in the diagnosis of preoperative orbital computed tomography (CT) in our patients with open globe injury and to evaluate the affecting factors.
Materials and Methods
The data of patients who underwent open globe injury repair between September 2014 and February 2021 in the Akdeniz University Hospital Ophthalmology Clinic were retrospectively analyzed. Demographic data of 290 patients’ were recorded. Patients suffer from corneal, scleral and corneoscleral injury; classified as pediatric and adult age groups. The presence of open globe injury, foreign body(FB) and orbital fracture in the preoperative orbital CT report were recorded.
Sixty (20.7%) women and 230 (79.3%) men were included in the study. Of the patients, 58 (20%) were pediatric and 232 (80%) were adults. There were corneal, 76 (26.2%) scleral, and 59 (20.3%) corneoscleral injuries in 155 (53.4%) patients. In the preoperative orbital CT report, it was stated that 163 (56.2%) patients had open globe injuries. We did not observe any statistical difference between the diagnostic efficiency of orbital CT in pediatric and adult groups (p=0.636). When we evaluate according to the location of wound; scleral and corneoscleral injuries were compared with corneal injuries, we found that orbital CT was more effective in diagnosing (p<0.001). Similarly, as the length of wound increased, the diagnostic efficiency of orbital CT increased (p<0.001).
In this study, we found the sensitivity of orbital CT in diagnosing open globe injury as 56.2%. Diagnostic efficiency increases in the presence of scleral and corneoscleral injuries and a full-thickness incision greater than 4 mm. We found that age, gender, and presence of orbital fracture had no effect on the sensitivity of orbital CT in diagnosing open globe injury. It should be kept in mind that nearly half of the patients may miss the diagnosis by orbital CT.
