*Significant P values are noted in right column of the Table. Statistical analysis was done with non parametric Kruskal-Wallis and Fisher’s exact tests for the comparison of dosage of different cytokines between idiopathic uveitis and controls in aqueous humor (medianes of concentrations). A P value < 0.05 was considered significant.
