Aim and background: The study aims to determine the accuracy of utilizing a temporal view in the detection of a shallow anterior chamber (AC), in comparison to the conventional anterior view, by evaluation of photographs of the anterior segment of the eye.
Materials and methods: Two hundred fifty students who had completed basic undergraduate ophthalmology training as part of their medical education graded the AC depth in anterior segment photographs as “shallow” or “not shallow.” Each eye was photographed from the anterior and temporal views. A total of 40 photographs of 20 eyes were provided.
Results: The ability to detect a shallow AC by temporal view had a sensitivity of 73.3%, compared to 63.2% in the anterior view. The specificity of the temporal view was better at 66.2% compared to the anterior view, which was 65.3%. The overall accuracy of the temporal view in detecting a shallow AC was higher than the anterior view (68.3 vs 64.7%, respectively). Combining both techniques increased the detection of a shallow AC to 88.3%.
Conclusion: In our study, the temporal view was more accurate in detecting a shallow AC compared to the anterior view. Integrating the temporal view of AC depth assessment with the traditional anterior view further improves the chances of detecting a shallow AC.
