Figure 4. The secondary delayed ocular (conjunctival + corneal) responses (SDYOR) were recorded in 8 patients. A:The mean score of particular factors recorded during the SDYOR: hollow square= Histamine; hollow triangle = Tryptase; crossed circle= ECP; hollow star = EDN; hollow triangle with vertical line = LTB₄; hollow rhombus = LTC₄; cross = LTE₄ ; solid star = MPO; solid rhombus = IFN-γ; solid triangle with vertical line= IL-2; solid square = IL-;, solid triangle= IL-5. B:The total mean score of ocular signs and symptoms recorded during the SDYOR (●) and PBS (x). C:The mean rhinomanometric values (NPG) recorded during delayed nasal response to allergen challenge (○) and control challenge with phosphate-buffered saline (PBS, x). I = Initial (baseline) values; ALL = Nasal challenge with allergen.
