Interocular Asymmetry of Foveal Thickness in Parkinson Disease
Figure 1
The central yellow dot in this illustration represents fixation at the foveola. The measuring grid visible in the background is centered on the foveola. Thicknesses at each of the intersecting points of the grid and calculated the volume of each 0.25 × 0.25 mm voxel. (a) shows the SD-OCT profiles through the fovea for a control subject and (b) SD-OCT profile for a PD patient.
