1. A method of analyzing the eye of a patient using a swept source optical coherence tomography (OCT) system, said method comprising: collecting a series of OCT data over a series of transverse locations in the eye, wherein the data is collected at two different axial resolutions, wherein the OCT system includes detection electronics and wherein the detection electronics remain unchanged as the axial resolution is adiusted; processing a first portion of the data to determine motion contrast wherein the first portion of the data was collected at the lower axial resolution; processing a second portion of the data to generate a structural image, wherein the second portion of the data was collected at a higher axial resolution wherein the two different axial resolutions are achieved by switching the swept source between at least two spectral tuning ranges and sweep rates, where the higher sweep rate corresponds to a shorter spectral tuning range; generating an en face vascular image with the first portion of the processed data; and storing or displaying the second portion of the processed data.
