Proportion of Eyes Classified as Slow, Moderate, and Fast Progressors According to the Rates of Change of Spectral-Domain Optical Coherence Tomography (SD OCT) Retinal Nerve Fiber Layer (RNFL) Thickness. Eyes Are Grouped According to the Percentage of Visits with Intraocular Pressure (IOP) Below (A) 21mmHg, (B) 18mmHg and (C) 15mmHg During Follow-up.

Rates of SD OCT global RNFL thickness change: slow, if slower −1.0 μm/year; moderate, if between −1.0 and −2.0 μm/year; fast, if faster than −2.0 μm/year.
