Erratum

Erratum in: In “Quantitative Analysis of Retinal Ganglion Cell (RGC) Loss in Aging DBA/2NNia Glaucomatous Mice: Comparison with RGC Loss in Aging C57/BL6 Mice” by Danias et al. (Invest Ophthalmol Vis Sci. 2003;44:5151–5162), the authors discovered an error in Table 1 of the above manuscript. The numbers in the fourth column are incorrect. The ratio of columns 3 and 4 should result in the fifth column numbers, but does not. Below is the corrected table . 

The online version of this article was corrected on January 28, 2004, in departure from print.

 Density was calculated as total RGC count divided by total retinal area. Data are expressed as the mean ± SEM.
