DualTrack Technology Improves Optical Coherence Tomography Angiography Image Quality

Ophthalmic Surg Lasers Imaging Retina. 2017 Nov 1;48(11):918-926. doi: 10.3928/23258160-20171030-08.

Abstract

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. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:918-926.].
