    en.wikipedia.org/wiki/Horner's_syndrome

    Horner's syndrome, also known as oculosympathetic paresis, [1] is a combination of symptoms that arises when a group of nerves known as the sympathetic trunk is damaged. The signs and symptoms occur on the same side (ipsilateral) as it is a lesion of the sympathetic trunk.

  3. 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 .

  4. Pupillary response - Wikipedia

    en.wikipedia.org/wiki/Pupillary_response

    Pupillary response is a physiological response that varies the size of the pupil between 1.5 mm and 8 mm, [1] via the optic and oculomotor cranial nerve. A constriction response , [2] is the narrowing of the pupil, which may be caused by scleral buckles or drugs such as opiates/opioids or anti-hypertension medications.

    The pain is typically greater than in other headache conditions, including migraines, and is usually described as burning, stabbing, drilling or squeezing. [15] While suicide is rare, those with cluster headaches may experience suicidal thoughts (giving the alternative name "suicide headache" or "suicidal headache").

  7. Retinal migraine - Wikipedia

    en.wikipedia.org/wiki/Retinal_migraine

    The aura phase of migraine can occur with or without a headache. Ocular or retinal migraines happen in the eye, so only affect the vision in that eye, while visual migraines occur in the brain, so affect the vision in both eyes together. Visual migraines result from cortical spreading depression and are also commonly termed scintillating scotoma.

  8. Mydriasis - Wikipedia

    en.wikipedia.org/wiki/Mydriasis

    Conversely, parasympathetic stimulation causes contraction of the circular muscle and constriction of the pupil. The mechanism of mydriasis depends on the agent being used. It usually involves either a disruption of the parasympathetic nerve supply to the eye (which normally constricts the pupil) or overactivity of the sympathetic nervous ...

    Recurrent painful ophthalmoplegic neuropathy (RPON), previously known as ophthalmoplegic migraine (OM), is a rare neurological disorder that is characterized by repeated headache attacks and reversible ipsilateral paresis of one or more ocular cranial nerves (CN). [1]
