  2. Parinaud's syndrome - Wikipedia

    en.wikipedia.org/wiki/Parinaud's_syndrome

    Parinaud's syndrome is a cluster of abnormalities of eye movement and pupil dysfunction, characterized by: Paralysis of upwards gaze: Downward gaze is usually preserved. This vertical palsy is supranuclear , so doll's head maneuver should elevate the eyes, but eventually all upward gaze mechanisms fail.

  3. Argyll Robertson pupil - Wikipedia

    en.wikipedia.org/wiki/Argyll_Robertson_pupil

    A third cause of light-near dissociation is Parinaud syndrome, also called dorsal midbrain syndrome. This uncommon syndrome involves vertical gaze palsy associated with pupils that “accommodate but do not react." [5] The causes of Parinaud syndrome include brain tumors (pinealomas), multiple sclerosis and brainstem infarction.

  4. Pinealoma - Wikipedia

    en.wikipedia.org/wiki/Pinealoma

    Frequently, paralysis of upward gaze along with several ocular findings such as convergence retraction nystagmus and eyelid retraction also known as Collier's sign and Light Near Dissociation (pupil accommodates but doesn't react to light) are known collectively as Parinaud's syndrome [1] or Dorsal Mid-brain syndrome, are the only physical ...

  5. Accommodative excess - Wikipedia

    en.wikipedia.org/wiki/Accommodative_excess

    Parinaud's syndrome, which can mimic some aspects of spasm of the near reflex, such as excessive accommodation and convergence; however, pupillary near-light dissociation, not miosis, is a feature of Parinaud's syndrome. [8]

  6. Ophthalmoparesis - Wikipedia

    en.wikipedia.org/wiki/Ophthalmoparesis

    Dorsal midbrain structures, as in Parinaud's syndrome. Certain parts of the cerebral cortex (including the frontal eye fields), as in stroke. Toxic envenomation by mambas, taipans, and kraits. Thiamine deficiency can cause ophthalmoparesis in susceptible persons; this is part of the syndrome called Wernicke encephalopathy. The causal pathway by ...

  7. Oculomotor nerve palsy - Wikipedia

    en.wikipedia.org/wiki/Oculomotor_nerve_palsy

    Oculomotor nerve palsy or oculomotor neuropathy [1] is an eye condition resulting from damage to the third cranial nerve or a branch thereof. As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements (four of the six extraocular muscles, excluding only the lateral rectus and superior oblique).

  8. Internuclear ophthalmoplegia - Wikipedia

    en.wikipedia.org/wiki/Internuclear_ophthalmoplegia

    Internuclear ophthalmoplegia (INO) is a disorder of conjugate lateral gaze in which the affected eye shows impairment of adduction.When an attempt is made to gaze contralaterally (relative to the affected eye), the affected eye adducts minimally, if at all.

  9. Parinaud's oculoglandular syndrome - Wikipedia

    en.wikipedia.org/wiki/Parinaud's_oculoglandular...

    Parinaud's oculoglandular syndrome (POS) is a medical condition characterized by a specific set of symptoms affecting the eye and nearby lymph nodes. Named after the French ophthalmologist Henri Parinaud , it should not be confused with the neurological syndrome caused by a lesion in the midbrain which is also known as Parinaud's syndrome .
