The impact of motion artifacts on quantitative optical coherence tomography angiography analysis in Parkinson's disease

We have previously shown that OCTA imaging in PD patients can be challenging. Our data suggest that retinal perfusion is reduced in both plexuses in PD, which may serve as a noninvasive biomarker in the future. Yet, control of motion artifacts in OCTA measurements is critical in this motor-impaired cohort.

Automated summary

This study suggests that OCTA imaging in PD patients can be challenging and the control of motion artifacts is critical. The data indicate reduced retinal perfusion in both plexuses, which may serve as a noninvasive biomarker in the future.
