Paralysing an eye

[TheVirus]

Hey, i’ve seen in many medical shows that when a patient’s eye is paralysed with medication it seems to change colours (the iris turns black as far as i’ve seen). Does this really happen when someone’s eyes are paralysed? If it does happen, do u know why?

[zami’87.]

pupil widens(that’s why eyes seem black),iris can’t contract..for example because of oculomotor nerve damage.

quote zami’87.:

But, how does the fact that it can’t contract affect the colour?

the color of iris as itself is not affected, but the pupil is wide and seems to be black 😉
