Mydriasis Definition

Origin of Mydriasis

• Latin mydriāsis from Greek mudriāsis perhaps from mudros red-hot mass of metal in a forge (in reference to the more brilliant appearance of the dilated pupil to ancient physicians, as a result of light reflected off the fundus of the eye) possibly akin to mudān to be damp, dripping (mudros perhaps originally referring to molten iron)

  From American Heritage Dictionary of the English Language, 5th Edition

• From Latin mydriasis, from Ancient Greek μυδρίασις (mydriāsis, “undue enlargement of the pupil"), from μύδρος (mydros, “mass of red hot material in a forge"), possibly because the pupil is particularly bright or sparkling when dilated.
