RT: Retinal thickness; CS: Central subfield of ETDRS grid; GCL + IPL: ganglion cell layer and inner plexiform layer; RNFL: Retinal nerve fiber layer.
The letters ^{a, b, c, d, e}indicate significant difference between the groups (a: p = 0.032, b: p = 0.039,c: p = 0.003,d: p < 0.001 , e: p < 0.001).
