Dilation of the pupil is known as mydriasis and contraction as miosis. Both mydriasis and miosis can be physiological. Other symptoms include increased sweating, salivation, bronchial secretions along with miosis (constricted pupils). Body temperature was not affected; there was also mydriasis followed by miosis, and hypersalivation. An additional mnemonic is MUDDLES&colon; miosis, urination, diarrhea, diaphoresis, lacrimation, excitation, and salivation. When caused by Horner's syndrome, ptosis is usually accompanied by miosis and anhidrosis. Involvement of T1 may result in Horner's syndrome, with ptosis, and miosis. The signs of Horner's syndrome are ptosis, miosis, anhydrosis, and (apparent) enophthalmos. Activation of the KOR is associated with spinal analgesia, miosis (pinpoint pupils), and psychotomimetic effects. Intraocular administration is used to produce miosis after lens implantation during cataract surgery. The opposite, constriction of the pupil, is referred to as miosis. Another term for the constriction of the pupil is miosis. Unlike other opioids, it does not cause miosis because of its anticholinergic properties. It inactivates the dilator muscle and thereby produces miosis. One of the first observable signs of a soman poisoning is miosis.
