Purpose To determine the correlation of the peripapillary retinal nerve fiber layer thickness (RNFLT) and macular thickness (MT) with type and degree of refractive errors. Methods Seventy‐four (37 myopic and 37 hyperopic) subjects with the mean age of 26.47 ± 0.75 years were participated in this study. Visual acuity (VA), Refractive errors (RE), axial length (AL), Intra ocular pressure (IOP) and corneal power (CP) were determined. RNFLT were measured by cirrus OCT using circular scan with diameter 3.4mm around optic disc, and MT was captured using radial scan in a 200 × 200mm area, Independent student T‐test was performed to compare the CP, RNFLT, MT and AL between groups. The correlation of the AL with RNFLT and MT were assessed using the Pearson correlation. Results There was a significant difference in AL between myopic and hyperopic eyes (p<0.05). In myopic eyes, the AL significantly correlated with RNFLT (p<0.001) and MT (p<0.05). Notwithstanding, axial length had no significant correlations with RNFLT and MT in hyperopic eyes. Also there is statistically significant relationship between MT and RNFLT with degree of the refractive errors in myopic eyes (p<0.05). Conclusion The results of this investigation indicated that myopes have thinner RNFLT and MT than hyperopes. These results could help clinicians in diagnosis and management of the patients with glaucoma.
