Erratum in: “Optic Disc Progression in Glaucoma: Comparison of Confocal Scanning Laser Tomography to Optic Disc Photographs in a Prospective Study” by Chauhan et al. ( Invest Ophthalmol Vis Sci. 2009;50:1682–1691.) 
In Figure 1 , the liberal criterion for the Topographic Change Analysis requires the largest cluster of significant red superpixels to be at least ≥0.5% (not ≥0.1%) of the disc area (DA). This is consistent with the legend and the rest of the manuscript. The corrected figure is printed below. 
Figure 1.
 
Criteria for the TCA of the HRT and expert observers in classifying progression. For example, the most liberal TCA criteria required the largest cluster of significant red superpixels to be at least 0.5% of the disc area (DA) with a depth change of ≥20 μm. The most liberal criteria for the expert observers was a classification of probably no change, probably change, or definitely change (score, 1, 2, or 3).
