Figure 3. The secondary late ocular (conjunctival + corneal) responses (SLOR) were recorded in 13 patients. A: The mean score of particular factors recorded during the SLOR: 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-4; solid triangle = IL-5. B: The total mean score of ocular signs and symptoms recorded during the SLOR (●) and PBS (x). C: The mean rhinomanometric values (NPG) recorded during late nasal response to allergen challenge (○) and control challenge with phosphate-buffered saline (PBS, x). I = Initial (baseline) values; ALL = Nasal challenge with allergen.
