Abstract
Purpose
To compare retinal nerve fiber layer (RNFL) thickness obtained with Stratus optical coherence tomography (OCT) and Cirrus OCT.
Methods
Sixty-one normal eyes were evaluated with Stratus and Cirrus OCT on the same day, and the RNFL thicknesses measured by the two OCT machines were compared. The correlation between the two data sets was obtained using Pearson’s correlation coefficient. The correlation between RNFL thickness and the difference in data measured by the two OCT machines was then assessed.
