Statistical analysis of the differences between evaluated parameters from baseline to 24 months’ follow-up. MD, mean deviation measured with standard automatic perimetry (SAP); RNFL, overall retinal nerve fiber layer thickness; RNFL Sup, superior retinal nerve fiber layer thickness; RNFL Inf, inferior retinal nerve fiber layer thickness; RNFL Nas, nasal retinal nerve fiber layer thickness; RNFL Temp, temporal retinal nerve fiber layer thickness; GCC: overall ganglion cell complex thickness; GCC Sup, superior ganglion cell complex thickness; GCC Inf, inferior ganglion cell complex thickness measured with ocular coherence tomography (OCT). p, Paired Student t-test significance (values < 0.05 in bold; values < 0.005 in bold on gray).
