Comparison of peripapillary choroidal thickness between healthy subjects and patients with Parkinson’s disease - Fig 3

<p>Three-dimensional graphical representation of the peripapillary choroidal thickness (PPCT) measurements in controls eyes (teaching population in left fig, validating population in middle fig) and Parkinson´s disease (PD) eyes in right fig. Grey, cubes corresponding with the optic nerve head; yellow, PPCT <105 μm; green, mean PPCT ranging from 105 to 139 μm; blue, mean PPCT ranging from 140 to 174 μm; and orange, mean PPCT ≥175 μm.</p

Diagnostic ability of inner macular layers to discriminate early glaucomatous eyes using vertical and horizontal B-scan posterior pole protocols - Fig 1

<p><b>Representative optical coherence tomography (OCT) horizontal scan section of the macula of a normal (A and B) and early glaucomatous (C and D) left eye</b>. Macular ganglion cell layer (mGCL) is marked with two asterisks, and retinal nerve fiber (mRNFL) layer is marked with one asterisk, in Fig 1B (normal eye) and 1D (glaucomatous eye). The automated segmentation performed by the OCT Spectralis software between mRNFL and mGCL is shown with a light blue line, and between mGCL and inner plexiform layer is shown with a purple line. We can appreciate a slight thinning of mGCL in the glaucomatous eye, especially temporal to fovea. Optic nerve head (ONH) position and fovea (Fo) are indicated. The infrared image obtained with the Horizontal Posterior Pole protocol of Spectralis OCT is shown in the corner of each B-scan. The green lines of the infrared image delimit the square scanning area at the posterior pole.</p

Comparison of peripapillary choroidal thickness between healthy subjects and patients with Parkinson’s disease - Fig 4

<p>Representation of the mean peripapillary choroidal thickness (PPCT) for the 26×26 cube-grid centered on the optic disc for the three groups: the 40 right healthy eyes of the teaching population (left fig), the 40 right eyes of the healthy validating population (middle fig), and the 40 right eyes of the Parkinson´s disease (PD) patient group (right fig). Grey, cubes corresponding with the optic nerve head; yellow, mean PPCT <105 μm; green, mean PPCT ranging from 105 to 139 μm; blue, mean PPCT ranging from 140 to 174 μm; and orange, mean PPCT ≥175 μm. The temporosuperior choroid is the thickest, followed by superior, temporal, nasal, and inferior choroid.</p

Abbreviation: C0, central fovea; IS, inner superior; IN, inner nasal; II, inner inferior; IT, inner temporal; OS, outer superior; ON, outer nasal; OI, outer inferior; and OT, outer temporal; RE, right eye; LE, left eye.</p
