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

Table 2

Pearson’s correlation coefficient () between GCC thickness by OCT-HS100 and GC-IPL thickness by Cirrus HD-OCT ( = 92).

GCC: ganglion cell complex; GC-IPL: ganglion cell-inner plexiform layer.
All values were statistically significant ().
^†Macular GC-IPL thickness was measured over 4 mm vertical diameter and 4.8 mm horizontal diameter.
^‡Overall average and superior and inferior hemifields GCC thicknesses were computed over 10 mm in diameter centered on the fovea.
Macular average GCC thickness was measured over 5 mm in diameter.
