چکیده مقاله:

Purpose: To report the data of ultrasound biomicroscopy (UBM) and anterior segment optical coherence tomography (AS-OCT) (CASIA II) in the evaluation of posterior capsule in traumatic cataract. Methods: 67 patients were included in this study. We included just mature and near mature traumatic cataracts. All patients underwent lensectomy after blunt trauma or after primary repair of an open globe injury. All patients underwent UBM and AS-OCT before lensectomy and any finding of the status of the posterior capsule was recorded. Results: The mean age of patients was 34.19 and the youngest was 6 years of age and the oldest patient was 71 years old. In the posterior capsule imaging by CASIA2, it was closed in 42(62.7%) patients. In the postoperative findings, posterior capsule was closed in 34(50.7%) patients and opened in 33(49.3%) patients. OCT significantly correlated with UBM (r=0.468 ) .For UBM, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 44%, 82%, 66% and 65%,respectively. For AS-OCT, sensitivity, specificity, PPV and NPV were 63%, 88%, 84%, and 71%, respectively. Conclusion: Both UBM and AS-OCT could predict the presence of posterior capsular opening before surgery with great sensitivity.
