Reflex contraction of the sphincter muscle of the iris in response to a bright light (or certain drugs) causing the pupil to become smaller.
1
Initial stimulation of these receptors leads to symptoms such as tachycardia, miosis, and tremors.
2
The shrinking of the pupil (miosis) caused by this drug limits your ability to adapt to darkness.
3
As measured by infra-red video pupillography, complete miosis occurred within 3.5 to 4.0 min after the application of DFP.
4
We report the case of a 42-year-old male patient who presented with ipsilateral ptosis and miosis and was subsequently diagnosed with internal carotid artery dissection.
5
In beagles PGF2 alpha-IE induced a strong miosis lasting more than 6 hours; Iloprost-PE had no effect on pupil size.
6
Methods: Miosis was induced by topical 1% pilocarpine in the right eye of 14 healthy subjects with normal eyes.
