Parinaud's syndrome is a constellation of neurological signs indicating injury to the dorsal midbrain. More specifically, compression of the vertical gaze center at the rostral interstitial nucleus of medial longitudinal fasciculus (riMLF).

2024年3月6日 · Parinaud syndrome, also known as dorsal midbrain syndrome, is a supranuclear vertical gaze disturbance caused by pathology of the dorsal midbrain region, often, but not exclusively, via compression of the superior tectal plate.

We investigated the pathophysiology related to the signs and symptoms to better understand the symptoms of Parinaud’s syndrome: diplopia, blurred vision, visual field defects, ptosis, squint, and ataxia, and Parinaud’s main signs of upward gaze paralysis, upper eyelid retraction, convergence retraction nystagmus (CRN), and pseudo-Argyll ...

Parinaud syndrome is classically described by the triad of impaired upward gaze, convergence retraction nystagmus, and pupillary hyporeflexia. This condition has multiple potential etiologies. Patients may complain of difficulty looking up, blurred near vision, diplopia, oscillopsia, and associated neurological symptoms.

We investigated the pathophysiology related to the signs and symptoms to better understand the symptoms of Parinaud’s syndrome: diplopia, blurred vision, visual field defects, ptosis, squint ...

Parinaud syndrome is a relatively uncommon neuroophthalmologic syndrome named for French ophthalmologist, Henri Parinaud. Parinaud syndrome has been known by many different names including dorsal midbrain syndrome, Sylvian aqueduct syndrome, pretectal syndrome, and Koerber-Salus-Elschnig syndrome.

Parinaud syndrome most commonly involves paresis or palsy of upward vertical gaze, pupillary abnormalities, and various forms of nystagmus, though multiple other signs can be detected by an experienced examiner (8-1 0).

Parinaud's syndrome is an inability to move the eyes up and down. It is caused by compression of the vertical gaze center at the rostral interstitial nucleus of medial longitudinal fasciculus (riMLF).
