In 110\/118 eyes (93%), both examiners provided the same breeding recommendation (yes\/no). This translated into an agreement on the final breeding recommendation in 58\/60 dogs (97%). Examiners disagreed on pectinate ligament abnormality (PLA) grading in 19\/118 eyes and iridocorneal angle width (ICAW) grading in 9\/118 eyes. PLA grading disagreement was mostly observed between neighboring grades. Disagreement between PLA and ICAW grading sometimes occurred within the same eye accounting for an observed disagreement in iridocorneal angle abnormality (ICAA) grading in 19\/118 eyes in total.
