Figure 3

Comparison of ganglion cell layer (GCL) + inner plexiform layer (IPL) thickness between preoperatively (black bar) and postoperatively (white bar) in eyes with and without optic nerve bending. Graphs showed the superior (S) (a), superior nasal (SN) (b), inferior nasal (IN) (c), inferior (I) (d), inferior temporal (IT) (e), and superior temporal (ST) (f) sectors of the macular, respectively. There was no significant difference in pre- and postoperative GCL + IPL thickness in all sectors (all p > 0.05). Both preoperatively and postoperatively, GCL + IPL thickness in the inferior temporal (IT) and superior temporal (ST) sectors was significantly lesser in eyes with optic nerve bending than in eyes without optic nerve bending (both *p < 0.05).
