The two-tailed unpaired t-test was used to compare the clinical features of allergic conjunctivitis between patients who were positive and negative for serum dog-specific IgG. Ocular findings were assessed by slit lamp examination on a scale of 0-3 (0=normal, 3=severe) and the total score was calculated as the sum of the individual scores (0-30 points).
