Abstract: Purpose: To determine the reproducibility of the peripapillary retinal nerve fiber layer thickness and optic nerve head parameters measured with the optical coherence tomography (SD-OCT) in normal eyes. Methods: Thirty-four eyes of 34 healthy patients were included in the study. The Cirrus OCT optic disc cube 200x200 protocol was used to obtain three scans from each eye to evaluate the reproducibility. Intraclass correlation coefficient (ICC) was calculated for the measurements of retinal nerve fiber layer thickness and optic nerve head parameters. Results: The correlation was excellent for all measures of retinal nerve fiber layer thickness (ICC between 0.87 and 0.98). The same happened with the optic nerve head parameters (ranging from 0.83 to 0.99), with the exception of E/D vertical ratio (0.56). Conclusion: Measurements of peripappilary retinal nerve fiber layer thickness and optic nerve head parameters showed excellent reproducibility with Cirrus OCT, indicating that this instrument may be useful in the study of glaucoma. This study has some limitations, including the small number of cases studied, further studies are needed to corroborate our findings.
