Angle of orbital axes
Angle of orbital axes
Definition
The angle of orbital axes refers to the angle between the orbital axes. It can be calculated directly between the two orbital axes, or between one of the axes and the median plane of the skull.
It varies greatly between species, but can also vary greatly between individuals of the same species, as for example in the dog.
In dogs:
In mesocephalic individuals, the angle is around 60° between the two axes.
In brachycephalic individuals, the angle can rise to 100° between the two axes.
