The cells in each cell layer were counted on 12 different 50-μm-long areas across the width of the retina in either intact or 30-day regenerated retinas, and their percentages with respect to the total number of cells in each area was determined. The length of the rod photoreceptor outer segments was also measured and compared between both types of retinas. A Student t-test was performed to evaluate the results, and no statistically significant differences were found between the two groups. Abbreviations: ganglion cell layer (GCL); inner nuclear layer (INL); outer nuclear layer (ONL); photoreceptor (Pr.); standard deviation (St. Dev.).
