IGHE and seasonal allergic rhinitis: Spearman correlations found a strong significant correlation between self-reported hay fever and tear IgE levels (rho = 0.68, p < 0.001), palpebral roughness (rho = 0.60, p < 0.001), eye rubbing frequency score (rho = 0.60, p < 0.001), MiniRQLQ score (rho = 0.78, p < 0.001), QUICK score (rho = 0.74, p < 0.001), and lower LWE (rho = 0.65, p < 0.001) (Table S2).
