Interocular Asymmetry of Foveal Thickness in Parkinson Disease

Figure 4

The mean interocular difference map of all control subjects is depicted. Thickness measurements of the inner retina over the central grid of 2.5 × 2.5 mm were obtained, digitally reconstructed, and color-coded. Temporal side is on the left and nasal retina on the right side. Left eyes were reflected horizontally so that the temporal retina is directionally left and the nasal retina is directionally right.
