Analysis of Iridocorneal Angle Parameters. A. Schwalbe’s Line Distance (SLD) comparison between dogs and cats shows that the mean SLD in dogs was 2.306 ± 0.1539 mm, ranging from 1.980 to 2.510 mm, whereas in cats, the mean SLD was 3.089 ± 0.2143 mm, with a range from 2.630 to 3.410 mm. B. The Angle-Opening Distance (AOD) comparison reveals that in dogs, the mean AOD was 0.9908 ± 0.3474 mm, with values ranging from 0.6200 to 1.810 mm, while in cats, the mean AOD was 1.833 ± 0.3874 mm, ranging from 1.340 to 2.580 mm. C. The Iridocorneal Angle (ICA) comparison shows that the mean ICA in dogs was 15.56 ± 3.241 degrees, ranging from 10.40 to 22.00 degrees, whereas in cats, the mean ICA was significantly larger, at 30.27 ± 3.954 degrees, with a range from 23.73 to 37.00 degrees. For ease of interpretation of our results, statistical significance is indicated as follows: not significant (ns), p < 0.05 (*), p < 0.01 (**), p < 0.001 (***), and p < 0.0001 (****)
