Short-term effects of exercise on optic nerve and macular perfusion measured by optical coherence tomography angiography

Purpose: To evaluate the effects of exercise on optic nerve and macular perfusion using optical coherence tomography angiography. Methods: Thirteen eyes of 13 healthy volunteers were examined using a high-speed and high-resolution spectral-domain optical coherence tomography XR Avanti with a split-spectrum amplitude-decorrelation angiography algorithm. Blood pressure, heart rate, the mean area of the foveal avascular zone , and flow density on the optic nerve head and macula, before and after exercise were measured and analyzed. Results: Mean patient age was 27.3 ± 3.5 years. Heart rate, systolic and diastolic blood pressure increased significantly after exercise (P
