Abstract:Objective: To observe the ganglion cell complex (GCC) in non-glaucomatous youth with different refractions using Fourier-domain optical coherence tomography (FD-OCT), and to explore the association between axial length (AL) and GCC parameters. Methods: This was a cross-sectional, observational study. Ninety-four youth (94 eyes) were enrolled in a non-high myopia group and 62 youth (62 eyes) were enrolled in a high myopia group based on AL. The mean macular GCC thickness, superior-half GCC (GCC-S) thickness, inferior-half GCC (GCC-I) thickness, focal loss volume (FLV), global loss volume (GLV) and their ratio (FLV/GLV ratio, FGR) were measured. Linear regression was performed to analyze the correlation between AL and these parameters. The cut-off levels of the GCC parameters between the two groups were analyzed with the area under the curve (AUC) of the receiver operating functions. Results: Linear regression showed that the mean macular GCC thickness (β=-0.698, P<0.001), GCC-S thickness (β=-0.693, P<0.001) and GCC-I thickness (β=-0.672, P<0.001) are reduced as AL increases; FLV (β=0.115, P=0.155) was not significantly correlated with AL; GLV (β=0.346, P<0.001) was positively correlated while FGR (β=-0.473, P<0.001) was negatively correlated with AL. A t-test revealed that there are significant differences in the mean macular GCC thickness (t=7.398, P<0.001), GCC-S thickness (t=7.313, P<0.001), GCC-I thickness (t=7.022, P<0.001), GLV (t=-3.482, P<0.001) and FGR (t=5.361, P<0.001) between the high myopia and non-high myopia groups except for FLV (t=1.057, P=0.292). AUCGCC was 0.809 (P<0.001) and the best differential point was 99 μm; AUCGLV was 0.689 (P<0.001) and the best differential point was 3.42; AUCFGR was 0.711 (P<0.001) and the best differential point was 0.44; while AUCFLV was 0.546 (P=0.330). Conclusions: GCC parameters in non-glaucomatous youth can be evaluated by using FD-OCT, and some parameters change as the AL elongates.
