Repeatability of Perimacular Ganglion Cell Complex Analysis with Spectral-Domain Optical Coherence Tomography

Figure 2

Ganglion cell complex (GCC) thickness map of the right eye in OCT-HS100 Glaucoma 3D algorithm. The area bounded by the inner (1.5 mm) and middle (5 mm) circles forms the inner ring, while the area bounded by the middle (5 mm) and outer (10 mm) circles forms the outer ring. Thicknesses are averaged for the overall measurement, superior and inferior hemifields over the 10 mm diameter circle, and inner (macular GCC) and outer (perimacular GCC) subfields. The section of the nasal outer ring that encroached onto the optic disc and the central 1.5 mm in diameter area are excluded.
