A print out of inner macular analysis using SD-OCT in a patient with Alzheimer disease. The built-in viewer shows the color retinography, oct line scan, macular RNFL thickness (mRNFL), the ganglion cell layer + inner plexiform layer (GCL+) thickness, and the RNFL + GCL + IPL (GCL++) thickness. a Fundus color. The green square line demarcates the macular area scanned (7 × 7 mm) by the FD-OCT. b Optical coherence tomography (vertical scan) of macular area. Center pseudo-colored map of the measured thickness. Lower each grid in the 10 × 10 grid was color coded with no color (within the normal limit), yellow (outside of the 95 % normal limit), or red (outside of the 99 % normal limit)
