Reproducibility of retinal thickness measurements with retinal thickness analyser in healthy and glaucomatous subjects

Introduction: The retinal thickness analyser (RTA, Talia aatechnologies Ltd. Mevaseret Zion, Israel) is a novel non-invasive instrument developed for multiple optical crosssectional retinal visualization that provides quantitative measurements of retinal thickness. Conclusions: The results of this study indicate that RTA is a highly reproducible method for measuring retinal thickness. The intervisit variability of RTA measurements of 5.6% in glaucomatous patients, corresponding to .9 mm, is in accord with Weimberger who found a CV of 5.9% in normal eyes. In conclusion, RTA is a non-invasive, objective and reproducible method to visualize the quantitative profile of the retinal thickness in glaucomatous eyes.
