Purpose: To investigate the relationships between stereoscopic non-mydriatic retinal camera (NMRC), retinal nerve fi ber layer thickness (RNFLT), and visual fi eld (VF) parameters in different stages of glaucoma. Materials and Methods: This retrospective study included 112 eyes from 112 patients with glaucoma which were grouped according to the disc damage likelihood scale (DDLS) obtained by the NMRC: DDLS stage 1 (group 1, n=11), DDLS stage 2 (group 2, n=48), and DDLS stage 3 (group 3, n=53). Data of NMRC, RNFLT, and VF were compared and correlated. Results: All RNFLT measurements revealed that the group 3 had signifi cantly lower values in all sections (p<0.05 for all). The VF measurements revealed that although the mean deviation (MD) values were higher in the group 3, this difference was not statistically signifi cant (p=0.08). However, Hodapp-Anderson-Parrish (HAP) score was signifi cantly higher in the group 3 (p<0.01). The DDLS stage was signifi cantly correlated with MD (p<0.01, r=0.30), HAP score (p<0.01, r=0.35), and all RNFLT measurements (p<0.05 for all, r between -0.22 and -0.36). The vertical cup to disc (C/D) ratio was also signifi cantly correlated with MD (p<0.01, r=0.38), HAP score (p<0.01, r=0.36), and all RNFLT measurements (p<0.05 for all, r between -0.30 and -0.48). Conclusion: All the NMRC, RNFLT, and the VF measurements are comparable and discriminative devices in staging glaucoma. The DDLS stage and vertical C/D obtained by NMRC are useful parameters in the monitoring glaucoma.
