Figure 1. Aqueous humour and serum concentrations of ascorbic acid (n=30 patients per group).

Measurements of concentrations of ascorbic acid in aqueous humour indicated significantly decreased (P<0.001) level in patients with developed XFG and late XFS compared to patients of other two groups. There was no statistical significant difference in serum concentration of ascorbic acid in all examined groups. ^aP<0.05, ^bP<0.001.
