OCT Repeatability

Investigative Ophthalmology and Visual Science. 2006;47:964-967

This paper reviews the reproducibility of OCT in evaluating RNFL thickness average. It concludes:

"A retinal-tracking system was successfully developed and integrated into a commercial OCT unit. Tracking OCT improved the consistency of scan registration, but did not influence NFL thickness measurement reproducibility in this small sample study."

I have found that OCT monitoring of RNFL year to year is meaningless unless the patients previous scan is brought up and the same scan loci are used.
