Choroidal Vascular Density on C-Scans: Macular (6×6 mm) versus Regional (500×500 microns).

AMD = age-related macular degeneration; Control = epiretinal membranes; early AMD patients = drusen, advanced reticular patients = reticular pseudodrusen with advanced atrophic or neovascular AMD.
Ac = Analysis of covariance (ANCOVA) p-value. Model 1. Adjusting for choroidal thickness. Model 2. Adjusting for age and gender. When the ANCOVA was statistically significant (p<0.05), Bonferroni adjusted p-values were calculated for the pairwise comparisons. NS = non-significant (p>0.05).
*When comparing Drusen vs early reticulars, p = 0.004, while all other comparisons were non-significant.
