BACKGROUND AND OBJECTIVE: To evaluate the effects of DualTrack Motion Correction Technology on the performance of AngioVue optical coherence tomography angiography (Optovue, Freemont, CA). PATIENTS AND METHODS: Fifty subjects underwent two consecutive examinations with AngioVue. The operator inactivated the eye-tracking (ET) technology before the second examination. Two operators measured execution time, excluded low-quality images, and counted the number of motion artifacts per image. RESULTS: The mean execution time was lower without ET in all the groups (P < .05), regardless of retinal diseases. Percentages of available images and low-quality images were 75.0% and 25.0%, respectively, with ET and 63.0% and 37.0%, respectively, without ET. Mean number of motion artifacts was significantly lower in images obtained using ET compared to images obtained without ET in all the groups (P < .0001), regardless of retinal diseases. CONCLUSION: Although ET technology increases the mean execution time, the reduction of motion artifacts and the increase of high-quality images may represent a great advantage in clinical practice. © 2017, Slack Incorporated.
