Questions & Answers about Межзрачковое расстояние и внутриглазное давление измерили.
Russian often leaves out they when the subject is unknown, unimportant, or obvious from context.
So измерили literally means they measured, but here it is better understood as:
- They measured the interpupillary distance and intraocular pressure
- or in more natural English, The interpupillary distance and intraocular pressure were measured
This is very common in medical, official, and procedural language.
Because the verb agrees with an implied plural subject: they.
It does not agree with расстояние or давление here, because those words are the things being measured, not the doers of the action.
So:
- измерили = they measured
- plural because the hidden subject is plural
