Serial Analysis

Detecting RNFL Change Over Time

Our service includes a Serial Analysis print out on all repeat patients. This allows for easy monitoring and early detection of eye disease progression. The GDx VCC monitors RNFL change over time and displays this analysis in a print out called Serial Analysis. The Serial Analysis printout has five key elements that should
be considered when assessing Retinal Nerve Fiber Layer (RNFL) change over time. These elements include the Thickness Maps, Deviation Maps, Deviation from Reference Maps, Parameters Tables, and TSNIT Graph. Serial Analysis can compare up to four exams. The exams are in order from earliest to most recent. The first exam is the baseline or reference exam, and all follow-up exams are compared to this baseline exam.
