interpapillary separation between the two eyes gen.

[Nel]

Помогите, пожалуйста, перевести: interpapillary separation (between the
two eyes)
Контекст: Stereopsis is themost important cue for depth perception. It
is the consequence of interpapillary separation between the
two eyes, 6 cm, which causes each eye to have a slightly
different view of the same scene.
Заранее спасибо!
