  2. Miosis - Wikipedia

    en.wikipedia.org/wiki/Miosis

    Nerves involved in the resizing of the pupil connect to the pretectal nucleus of the high midbrain, bypassing the lateral geniculate nucleus and the primary visual cortex. From the pretectal nucleus neurons send axons to neurons of the Edinger-Westphal nucleus whose visceromotor axons run along both the left and right oculomotor nerves .

  3. Pupillary response - Wikipedia

    en.wikipedia.org/wiki/Pupillary_response

    Dilation and constriction of the pupil. Pupillary response is a physiological response that varies the size of the pupil, via the optic and oculomotor cranial nerve.. A constriction response (), [1] is the narrowing of the pupil, which may be caused by scleral buckles or drugs such as opiates/opioids or anti-hypertension medications.

  4. Mydriasis - Wikipedia

    en.wikipedia.org/wiki/Mydriasis

    Mydriasis is the dilation of the pupil, usually having a non-physiological cause, [3] or sometimes a physiological pupillary response. [4] Non-physiological causes of mydriasis include disease, trauma, or the use of certain types of drug. It may also be of unknown cause.

  5. Pupillometry - Wikipedia

    en.wikipedia.org/wiki/Pupillometry

    Greater pupil dilation is associated with increased processing in the brain. [45] Vacchiano and colleagues (1968) found that pupillary responses were associated with visual exposure to words with high, neutral or low value. Presented low-value words were associated with dilation, and high-value words with constriction of a pupil. [46]

  6. Adie syndrome - Wikipedia

    en.wikipedia.org/wiki/Adie_syndrome

    Adie's pupil is supersensitive to ACh so a muscarinic agonist (e.g. pilocarpine) whose dose would not be able to cause pupillary constriction in a normal patient, would cause it in a patient with Adie's Syndrome. The circuitry for the pupillary constriction does not descend below the upper midbrain, henceforth impaired pupillary constriction is ...
