HD-OCT RNFL measurements highly reproducible
Cirrus™ high-definition (HD) OCT (Zeiss) provides peripapillary RNFL thickness measurements that are highly reproducible and repeatable both between different sessions and between different operators, according to an observational study. The study involved two experienced examiners who each assessed 68 eyes of 68 healthy volunteers in two different sessions. The average RNFL thickness ranged from 90.97 µm to 91.46 µm and from 91.34 µm to 91.78 µm, for the first and the second operator, respectively. Intra-session repeatability as tested by coefficient of repeatability was next to the device resolution, with very similar results between the two operators. However, when analysing quadrant and clock hour sector RNFL thickness measurements, both repeatability and reproducibility tend to decrease.
