Patients and Methods
The study was approved by the Institutional Review Boards of the University of Texas Southwestern Medical Center and Parkland Memorial Hospital. The medical records of all patients taken to the operating room at Parkland Memorial Hospital between October 1, 1998, and September 30, 2003, for known or suspected open-globe injury were reviewed. Patients younger than 18 years and those who did not undergo preoperative CT scanning were excluded, as were patients whose CT films could not be located
Results
Fifty-two eyes of 50 patients underwent surgical exploration to rule out occult open-globe injury. The CT films could not be located for 4 unilateral patients, leaving 48 eyes of 46 patients for analysis. Axial images were obtained for all patients, whereas additional coronal imaging was available for 35 (73%) of the 48 eyes. The mean age of the patients was 36 years (range, 19–84 years), and 38 (83%) were men. Twenty-eight (58%) of the 48 injured eyes were left eyes. Latino persons accounted
Discussion
Computed tomography provides valuable information to the ophthalmologist assessing the traumatized eye. We found that preoperative CT scanning for diagnosis of occult open-globe injuries (by original radiographic interpretation) had sensitivity of 71%, specificity of 76%, and PPV of 89%. Joseph et al5 retrospectively reviewed 200 patients who underwent preoperative CT scanning for eye injuries and found sensitivity, specificity, and PPV of CT in the diagnosis of open-globe injury to be 75%,

2023, American Journal of Emergency MedicineCitation Excerpt :Another retrospective study found the sensitivity and specificity of CT were 51–77% and 97%, respectively [73]. A third retrospective study of 200 patients presenting from 1989 to 1993 found the sensitivity and specificity of CT to be 75% and 93% [81], while a retrospective study of 46 patients found the sensitivity and specificity of CT were 56–68% and 79–100%, respectively [82]. Based on the data, overall CT sensitivity ranges from 51 to 77% and specificity from 79 to 100% [51,70,73,81,82].
